Colombian Pacific · July – October
Colombia Whale Watching
Every year between July and October, more than three thousand humpback whales travel 8,500 km from Antarctica to give birth off the Colombian Pacific coast. It’s one of the most reliable and least crowded wildlife shows on the planet.
What is Colombia’s humpback whale season?
The Southern Hemisphere humpback whale (Megaptera novaeangliae), known as Stock G, spends the austral summer feeding on krill in Antarctic waters. When austral winter arrives, it travels toward the equator on one of the longest documented migrations of any mammal: roughly 8,500 kilometers to the warm waters of the Eastern Tropical Pacific, where it gives birth, nurses calves, and breeds. Colombia is one of the three countries with the most reliable humpback whale sightings —alongside Ecuador and Costa Rica— and the most accessible for travelers who want to combine Colombia whale watching with rainforest.
The season runs from late June to early November, with peak sightings between August and September. At peak, boat outings from Bahia Solano, Nuqui, Bahia Malaga, and Gorgona have a 90 to 95% sighting probability. It’s not a guarantee — the whale doesn’t sign a contract, and there are always offshore days with nothing — but the reliability is very high and on par with the world’s best windows.
8,500 kilometers: the Stock G migration
Stock G is the Southern Hemisphere population of humpback whales that feeds between the Antarctic Peninsula and the South Sandwich Islands during the austral summer (December–March), and breeds off the Eastern Tropical Pacific —from Peru to southern Mexico— during the austral winter (June–November).
Why they travel 8,500 km
Calves are born without the blubber layer they need to survive in cold water. Pregnant females migrate to tropical waters (24–28 °C / 75–82 °F) to give birth, nurse the calf for 6–10 months, and let it build the fat it needs before heading back south. The mother barely feeds during this entire period: she lives off reserves built up in Antarctica. A calf gains up to 50 kg per day in its first month, drinking around 200 liters of milk at 35% fat.
The behaviors you see
In Colombian waters, three behaviors dominate: breaching, where the whale launches almost fully out of the water and lands on its side; lobtailing, a sustained slap of the tail fluke on the surface; and pectoral fin extension, which on the humpback is the longest of any whale (up to 5 m). These are social, likely communicative behaviors, and they give the sighting its spectacle.
The humpback song
Males sing complex, structured songs that can last up to 30 minutes and repeat for hours. Each population has its own dialect, and within a season every Stock G male converges on the same song — cultural transmission across roughly 6,000 individuals. Some Pacific lodges offer hydrophones so you can listen to the songs from the boat or from your room: it’s worth asking for.
The four whale-watching zones in Colombia
There are four operating zones for whales in Colombia, each with its own personality. The choice isn’t just logistics: each zone offers a distinct mix of probability, infrastructure, complementary experiences (jungle, beach, island), and travel style.
Bahia Solano (Choco)
The classic option for Bahia Solano whales. The town pairs whale watching with rainforest hiking (Utria, Playa Huina, El Valle). The most developed tourism infrastructure on the Choco Pacific: roughly ten lodges across price tiers. Cetology partnerships with the Macuaticos Foundation and national research centers.
Utria National Park is one hour away by boat and combines whales, jungle, and untouched beach. It’s the most complete combo in the region.
Nuqui (Choco)
Nuqui has a different style: more intimate, more exclusive lodges, more ambitious cuisine, and Afro-Colombian communities at Termales, Joviseo, and El Cabo more deeply integrated into the operation. Wider beaches, natural hot springs in the jungle, and active artisanal fishing.
Sighting probability matches Bahia Solano. It’s the preferred option for travelers who want nature with boutique-lodge comfort.
Bahia Malaga (Valle del Cauca)
Bahia Malaga is the most scientifically consolidated whale-watching zone: Uramba Bahia Malaga National Park was created in 2010, and the Yubarta Foundation —Colombia’s oldest humpback research center— has worked here for decades. The zone has more sightings per outing hour and the most frequent surface behaviors.
Lodging is more basic than in Choco: community cabins and the Juanchaco/Ladrilleros ecotourism lodge. It’s the science-and-education option par excellence.
Isla Gorgona (Cauca)
A former maximum-security prison turned National Park in 1985, Gorgona is a volcanic island of humid jungle with howler monkeys, the endemic blue lizard, and a marine area rich in humpbacks, spotted dolphins, and turtles. Lodging is controlled: only the National Parks ecotourism center, with limited capacity, and reservations months in advance.
It’s the most remote, highest-adventure option. Natural combo: whales + diving + island jungle on a single trip.

|---|---|
| Species | Humpback whale (Megaptera novaeangliae) — Southern Hemisphere Stock G |
| Migration distance | ~8,500 km from the Antarctic Peninsula to the Eastern Tropical Pacific |
| Season | Late June to early November. Peak: August–September |
| Sighting probability | 90–95% per outing at peak (Aug–Sep). 70–85% on shoulders (Jul / Oct) |
| Boat outing length | 2–4 hours, open ocean. Typical 7:00 a.m. departure |
| Group size on boat | 6–10 people depending on operator. We cap at 8 max for photography |
| Legal distance to whale | 200 m (Resolution 0157 of 2014, Ministry of Environment) |
| Regulatory framework | Resolution 0157/2014 forbids swimming, chasing, touching, or altering trajectory |
| Typical itinerary | 4–6 days. Flight from Medellin or Cali, lodge, 2–3 boat outings |
| Languages of operation | English, Spanish. German, French, and Portuguese with advance coordination |
Month by month: probability and behavior
The season isn’t uniform. There’s a ramp-up, a peak, and a tail with different dynamics. This matters when deciding when to travel — and what you want to see.
| Month | Probability | What to expect | Recommendation |
|---|---|---|---|
| Late June | 40–60% | First whales arrive, mostly scout males. Few calves. | Risk: season not yet consolidated. Best pricing. |
| July | 70–85% | Pregnant females arrive, first births. Courtship behavior. | Good window, less saturation than August. |
| August | 90–95% | Absolute peak. Maximum number of individuals. Small calves with mothers. | ★ Best month — book 4–6 months ahead. |
| September | 90–95% | Peak continues. Larger calves, more surface activity (breaches). | ★ Equivalent to August. Excellent for photography. |
| October | 70–85% | Return migration begins. Females with developed calves. Sea sometimes rougher. | Good window, with broader availability and pricing. |
| Early November | 30–50% | Closing days. Few whales remaining, longer outings to find them. | Only if your dates can’t reach the core window. |
Practical rule: if your main goal is whales, travel between August 1 and September 30. If you want drier weather (the region is rainy year-round), September tends to be drier than August.

How to reach the Colombian Pacific
The Colombian Pacific has no road access from the country’s interior. Access is exclusively by air or by sea from Buenaventura or Guapi. The Choco airports are small and flight availability is limited: booking 3–6 months ahead at peak is essential.
| Leg | Time | Detail |
|---|---|---|
| Medellin → Bahia Solano | ~1 h flight | 1–2 daily flights. Regional carriers (Satena). BSC airport. |
| Medellin → Nuqui | ~1 h flight | 1–2 daily flights. Short runway. NQU airport. |
| Cali → Buenaventura → Bahia Malaga | 3 h road + 1 h boat | Cali–Buenaventura highway, fast boat from the tourist dock to the lodge. |
| Cali → Guapi → Gorgona | 1 h flight + 2 h boat | Cali–Guapi flight, National Parks boat to the island. Confirm capacity ahead of time. |
| Charter flight | variable | For groups of 4+, consider a private small plane Bogota–Bahia Solano (~2 h). We quote per leg. |
Important: Pacific airports have luggage limits (15–20 kg checked maximum) and flights can be canceled by fog or heavy rain. We recommend flying to Bahia Solano or Nuqui with a buffer day before any international connection.
Precautions for a boat outing
Whale watching is a relatively safe activity, but it happens on the open Pacific, with possible swell and tropical rain. These are the precautions that matter.
Seasickness
The Colombian Pacific can have moderate to heavy swell, especially in the afternoon. Roughly one in five people gets seasick on a 3–4 hour outing. Prevention strategy:
- Take dimenhydrinate (Dramamine) 30–60 minutes before casting off — once you’re at sea, it’s too late.
- Light breakfast, no excess coffee, no alcohol the night before.
- On the boat, watch the horizon, don’t read or check your phone. Sit in the central middle, the most stable spot.
- Hydrate with water, not acidic juices. Salted crackers, candied ginger.
Sun and UV radiation
The Colombian Pacific sits 5° north of the equator: UV radiation is extreme, intensified by water reflection. Severe sunburn on the boat is the most common medical complaint. Water-resistant SPF 50+ sunscreen applied 30 minutes before and reapplied every 2 hours. Hat with chin strap, UV-blocking sunglasses, lightweight long-sleeved clothing (UPF rated if available). Constant hydration: 1 liter of water per person minimum on each outing.
Rain and tropical climate
Choco is one of the rainiest regions on the planet — up to 13,000 mm of annual rainfall in some spots. Outings can include sudden tropical downpours. Essentials: hooded waterproof jacket, dry bags for camera and phone, waterproof pouch for documents. Serious boats supply life jackets and plastic ponchos; check before casting off.
After the outing
Fresh-water shower as soon as you’re back at the lodge: salt water dries the skin and worsens late sunburn. Wash camera gear and lenses well (salt corrodes). Oral rehydration with rehydration salts if there was seasickness or prolonged sun exposure.
Vaccines and medications
Yellow fever vaccine recommended for the entire Colombian Pacific (some lodges require it). Hepatitis A and tetanus current. Malaria risk is low but present in adjacent jungle zones — consult a physician about prophylaxis if you’ll be hiking in the rainforest. 30%+ DEET repellent for mosquitoes at the lodge at sunrise and sunset.
What to bring on a Colombia whale watching outing
Minimal, functional packing list. Pacific humidity ruins cotton clothing — choose synthetic, fast-drying fibers.
| Category | Essentials |
|---|---|
| Optics | 8×42 binoculars (recommended for marine work). Camera with 200–400 mm tele if you’re shooting. Stabilizer optional. |
| Sun protection | SPF 50+ water-resistant sunscreen, hat with chin strap, polarized UV sunglasses, SPF lip balm. |
| Rain gear | Hooded waterproof jacket (not poncho), waterproof pants optional, ziplock bags. |
| Seasickness | Dimenhydrinate (Dramamine), salted crackers, candied ginger, your own water bottle. |
| Footwear | Marine sandals (not flat flip-flops), neoprene socks optional, jungle shoes for hikes (not white sneakers). |
| Electronics | Power bank, dry pouches for phone and camera, universal chargers (remote lodges sometimes have limited power). |
| Documents | Passport or ID, yellow fever vaccine card, printed travel insurance, emergency contact. |
What you’ll see beyond the humpback
A whale-watching outing on the Colombian Pacific isn’t only whales. The marine biodiversity of the Choco biogeographic region is among the richest of the Eastern Tropical Pacific.
Humpback whale
Megaptera novaeangliae
The headliner. Adult females reach 14–16 m and 30 tons. Pectoral fins up to 5 m long. Breaching, tail slaps, and song.
Calf
M. novaeangliae (juvenile)
Newborns measure 4–5 m and weigh ~1 ton. Gain up to 50 kg/day in their first month. Always alongside the mother.
Spotted dolphin
Stenella attenuata
Pods of up to 100 individuals in open Pacific waters. Frequent companions during outings.
Bottlenose dolphin
Tursiops truncatus
Coastal species, year-round resident. Smaller pods, curious behavior with boats.
Olive ridley turtle
Lepidochelys olivacea
Nests on Choco beaches between July and December. Occasional sightings from the boat.
Hawksbill turtle
Eretmochelys imbricata
Critically endangered. Occasional sightings near reefs and mangrove zones.
Giant manta ray
Mobula birostris
Sporadic sightings in open waters. Wingspan up to 7 m. More frequent at Gorgona and Bahia Malaga.
Seabirds
Sula spp., Fregata spp.
Boobies, frigatebirds, pelicans, and coastal herons accompany most outings. Excellent flight photography.
Responsible whale watching: the rules matter
Sloppy whale watching stresses the animals, separates mothers from calves, and can cause strandings. Colombia has one of the clearest regulations in the region — Resolution 0157 of 2014 from the Ministry of Environment — and we work only with operators who follow it to the letter.
- Minimum distance of 200 meters between boat and whale. If the whale approaches you, the engine cuts.
- Maximum 3 boats simultaneously around the same whale group. Maximum observation time per boat: 30 minutes.
- Maximum speed 4 knots on approach to the viewing area.
- Swimming and diving with whales is forbidden. Touching, feeding, and noise-making to attract them are all forbidden.
- No chasing, encircling, or cutting off mothers with calves. Approach must be parallel and from behind.
- The engine must be in neutral during close observation.
If your operator or skipper suggests breaking any of these rules, get off the boat. The responsible industry exists; you don’t need to support the other one.
How to combine whales with the rest of the country
The whale watching itself fits into 3–4 concentrated days. But staying in Colombia a little longer lets you fold in complementary regions.
Pacific + Rainforest (10–12 days)
The classic combination: 4 days of whales in Bahia Solano or Nuqui + 4–5 days of rainforest in the Amazon (Leticia, Puerto Narino, Palmari) or the Sierra Nevada de Santa Marta. Two radically different ecosystems: marine tropics and flooded jungle.
Pacific + Cartagena (8–10 days)
4 days of whales + 3–4 days in Cartagena with beach time at Islas del Rosario or Baru. The natural transition between intense nature and Caribbean decompression. Air connection via Medellin.
Pacific + Casanare (12–14 days)
For travelers who only come once and want maximum diversity: 4 days of whales + 5 days of Llanos safari in Casanare. Humid tropical rainforest + flooded savanna. The most complete wildlife combo in the country.
Pacific + Coffee Region (8–10 days)
A balanced combo: 4 days of whales + 4 days in cloud forest and coffee haciendas (Caldas, Quindio, Risaralda). Excellent for couples mixing intensity with comfort.
The Choco Pacific: Afro culture and cuisine
A whale-watching trip is more than the animal in the sea. The Colombian Pacific is the ancestral territory of Afro-descendant communities four centuries deep in the region, with a distinct culture —currulao, marimba, alabaos, rowing songs— recognized as Intangible Cultural Heritage of Humanity by UNESCO.
Currulao and the marimba
Currulao is the drum-and-marimba rhythm that defines the music of the southern Pacific. The chonta marimba —built from chontaduro palm wood with bamboo resonators— has a unique timbre that fuses percussion and melody. Some lodges arrange evenings with local groups: it’s worth asking, it’s one of the experiences that close a trip best.
Pacific cuisine
Choco cooking has three pillars: fresh fish (tuna, snapper, mackerel, snook, prawn), coconut, and aromatic herbs (wild cilantro, pennyroyal, basil). Signature plates: encocado (fish or prawn cooked in coconut milk), coconut rice with tuna, fish tapao, fish sancocho, crab stew. It’s a kitchen radically different from interior Colombia — lighter, fresher, more West African than Spanish in influence.
Host communities
Whale watching tourism in the Pacific works because Afro-Colombian communities decided it should: cooperatives of local boat operators, women cooks from the area, guides born in El Valle, Termales, or Joviseo. The tourism economy has (partly) replaced extractive fishing and logging. It’s a documented case of conservation through economic incentive.
FAQ: whale watching in Colombia
Is whale watching safe on the Colombian Pacific?
Yes, in consolidated tourism zones (Bahia Solano, Nuqui, Bahia Malaga, Gorgona). Licensed operators have RNT registration, insurance, life jackets, emergency radios, and they read the sea well. We always recommend operators with proper licensing and a biologist on board, not improvised dock vendors.
Which zone is best for whale photography?
Bahia Malaga has the highest sighting rate per hour and the most frequent surface behavior. Bahia Solano has better light because of how the bay is oriented. For serious photographers (200–400 mm) we recommend a private boat: we coordinate with operators who accept private bookings.
Can you see whales from the beach or do you have to take a boat?
Occasionally there are sightings from land — from Playa Huina, El Valle, La Plata, or Gorgona viewpoints. But reliable whale watching only happens by boat, 2–5 nautical miles offshore. A single 3-hour outing equals weeks of land-based watching.
How many outings do I need to see whales?
In August–September, a single 3-hour outing is usually enough (90–95% probability). We always recommend two outings: one to “guarantee” the sighting, another to go deeper into behaviors (breaches, calves, song with hydrophone). 4–6-day itineraries give flexibility if day one has rough seas.
Is it suitable for kids?
Yes from age 7–8, as long as the child handles the sea well. Smaller children may get seasick and a 3–4 hour outing is long. Choco lodges usually have alternative land-based activities (short hikes, beach, birding) for children who skip the boat.
What if I don’t see whales?
In August–September with 2 outings, the probability of not seeing whales is under 5%. Most serious operators offer an additional outing at no extra cost if the first produces no sighting. We arrange this at the booking stage.
Can I swim or dive with whales in Colombia?
No. Resolution 0157 of 2014 expressly forbids swimming, diving, or entering the water with humpbacks in Colombia. Countries like Tonga or the Dominican Republic allow it under different regulation; Colombia does not. We respect that.
How much does a whale-watching trip cost?
It varies by lodge category and length. As a benchmark: 5 days / 4 nights in Bahia Solano with a mid-tier lodge, 2 whale-watching outings, flights from Medellin, and all meals starts at roughly USD 1,800 per person. Boutique lodges in Nuqui rise to USD 2,800–3,500. Exact quote depends on dates and specific lodge.
How far ahead should I book?
To travel in August or September, book 4 to 6 months in advance. Flights to Bahia Solano and Nuqui have limited capacity and the best lodges fill up early. In October or July (shoulders), 6–10 weeks is enough.

Frequently Asked Questions
When is the best time to see whales in Colombia?
Humpback whales visit Colombia’s Pacific coast from June through November, with peak activity in August and September. The whales travel from Antarctic feeding grounds to the warm waters of the Colombian Pacific for calving and nursing.
Where are the best whale watching spots in Colombia?
The top locations are Bahía Solano, Nuquí, and Gorgona Island on the Pacific coast. Bahía Málaga near Buenaventura is also excellent and more accessible from Cali. Each offers a different combination of boat-based and shore-based observation opportunities.
How close can you get to the whales?
Colombian regulations require boats to maintain a minimum distance of 200 meters from whales. However, whales are naturally curious and frequently approach boats on their own, sometimes surfacing within just a few meters of the vessel.
Can you swim with whales in Colombia?
Swimming with whales is not permitted in Colombian waters. Regulations protect both the whales and visitors by restricting interactions to boat-based observation. The boat encounters are spectacular and allow extended observation of breaching, spy-hopping, and tail-slapping behaviors.
Is whale watching suitable for children?
Yes, whale watching is an excellent family activity. Most tours last 2-3 hours and children are fascinated by the scale and behavior of humpback whales. Calm Pacific bay conditions during whale season make seasickness uncommon.
