Scuba Diving in Cayos Cochinos

Diving in Cayos Cochinos

Diving in Cayos Cochinos is some of the most pristine reef diving in the Caribbean, and almost nobody outside of dedicated Honduras divers has heard of it. The archipelago sits 30 km northeast of La Ceiba on the Honduran mainland, between the coast and the Bay Islands of Roatan and Utila. Two small forested islands, Cayo Cochino Mayor (Cayo Grande) and Cayo Cochino Menor, anchor a string of 13 small coral cays surrounded by reef and seamounts. The whole area was declared a marine reserve in 1993, and commercial fishing, netting, and trapping have been banned ever since.

The result is what the rest of the Mesoamerican Reef would look like with thirty years of strict protection. Reefs are dense with hard and soft coral, sponges grow oversized, and fish life is genuinely abundant. Schools of jacks, snapper, and barracuda routinely block out the light around the seamounts. The Honduras Coral Reef Fund (HCRF) manages the park and enforces the no-fishing zone, and the absence of resort-scale dive infrastructure keeps boat traffic low.

Most divers come on day trips. La Ceiba and the nearby Garifuna village of Sambo Creek are the main launch points, with day boats running 1 to 1.5 hours out to the islands and offering a 1- or 2-tank dive plus a beach lunch. Roatan-based operators also run day trips and overnighters, though the longer crossing makes them more expensive. The single on-island accommodation, Plantation Beach Resort on Cayo Mayor, runs its own diving for guests, and a handful of Honduras liveaboards include Cayos Cochinos in their itineraries.

The 16 main dive sites cover the full range of skill levels. Average depths run 2 to 30 m, with shallow coral mazes around Lion's Head suiting newer divers and deep seamount walls at Roatan Banks rewarding more experienced divers. Visibility averages 30 m and currents are typically mild. Add a strict marine reserve, almost no other divers in the water, and an entry fee that goes directly to reef protection, and Cayos Cochinos punches well above its weight as a Bay Islands destination.

Top dive sites in Cayos Cochinos

Top dive sites in Cayos Cochinos cluster around the two main islands and the offshore seamounts, and the best of them are the open-water seamounts where pelagic fish school in numbers. These five are the consistent headliners.

Roatan Banks (Cocos Seamount)

Roatan Banks, also known as Cocos Seamount, is the most famous dive at Cayos Cochinos. The pinnacle rises from deep ocean floor to within 12 m of the surface, and currents wash nutrients up the structure, drawing in massive schools of jacks, snapper, and barracuda. On a good day, the schools are so dense they block out the light overhead. This is the dive to plan a Cayos Cochinos trip around.

• Depth: 12–35 m (40–115 ft)
• Visibility: 25–30 m
• Current: Moderate
• Level: Intermediate to advanced
• Key species: Schools of horse-eye jacks, cubera snapper, barracuda, large grouper, occasional eagle ray

Pelican Point

Pelican Point sits at the western end of Cayo Cochino Mayor and is one of the most-dived sites in the marine reserve. The reef structure mixes hard coral heads, gorgonians, and small drop-offs, with reef fish coverage that's denser than anywhere on Roatan. A solid all-around site with good macro on the shallow shelf and bigger fish along the slope.

• Depth: 5–25 m (15–80 ft)
• Visibility: 20–30 m
• Current: Gentle
• Level: All levels
• Key species: Hawksbill turtle, queen angelfish, French angelfish, schoolmaster snapper, lobster

Lion's Head

Lion's Head is the best site at Cayos Cochinos for newer divers and macro photographers. The dive runs over a sandy-bottom area on the north side of Cayo Grande with massive coral heads (50 to 100 ft across) rising from the sand to within 3 m of the surface. You weave between the towers in a kind of natural maze, finding fish, crabs, and rays in the channels.

• Depth: 5–18 m (15–60 ft)
• Visibility: 20–30 m
• Current: Gentle
• Level: All levels
• Key species: Southern stingray, hawksbill turtle, queen angelfish, banded coral shrimp, lobster

CJ's Garden

CJ's Garden is a seamount roughly 22 miles south of Roatan that rises from the deep blue to within 18 m of the surface. The pinnacle is coated in dense, healthy hard and soft coral, giant barrel sponges, and gorgonian sea fans, which makes it a scenic dive even when pelagic action is quiet. Drift along the side of the seamount as it falls away into the deep.

• Depth: 18–35 m (60–115 ft)
• Visibility: 25–30 m
• Current: Moderate
• Level: Intermediate to advanced
• Key species: Large grouper, schools of horse-eye jacks, eagle ray, sea fans, giant barrel sponges

Big Coco / Little Coco

Big Coco and Little Coco are a pair of small coral cays on the eastern edge of the marine reserve, often dived back-to-back as morning and afternoon tanks on a day trip. The reef around the cays mixes coral gardens, slopes, and small wall sections. Visibility is excellent and the area sees almost no boat traffic.

• Depth: 8–25 m (25–80 ft)
• Visibility: 25–30 m
• Current: Gentle
• Level: All levels
• Key species: Hawksbill turtle, large grouper, queen angelfish, schools of grunts, lobster

Best time to dive Cayos Cochinos

The best time to dive Cayos Cochinos is from February through June, when dry-season conditions deliver 30 m visibility, calm seas, and the most reliable boat-day forecasts. You can dive year-round, but November and December are the most weather-affected months — open-water crossings from the mainland and Roatan can get rough.

Day trips from La Ceiba and Roatan are weather-dependent because of the open-water crossing. If you're traveling specifically for Cayos Cochinos, book at the start of your trip and keep a buffer day, since one bad-weather day can knock out the entire reason you're in the area.

Diving conditions in Cayos Cochinos

Diving conditions in Cayos Cochinos are calm and clear most of the year. The reserve is sheltered enough that conditions hold up across most months, with the open-water seamounts seeing slightly more current than the protected sites near the islands.

Marine life in Cayos Cochinos

Marine life in Cayos Cochinos is the densest in the Bay Islands, a direct result of three decades of no commercial fishing inside the reserve. Predators are abundant, schooling fish are larger and more frequent, and reef structure is healthier than anywhere on Roatan or Utila.

• Pelagics: Spotted eagle ray, southern stingray, southern barracuda, schools of horse-eye jacks, cubera snapper, schools of grunts
• Reef dwellers: Hawksbill turtle, green turtle, large grouper, queen and French angelfish, midnight parrotfish, schoolmaster snapper, green moray eel, Caribbean reef squid, lobster
• Macro: Seahorses, frogfish, nudibranchs, blennies, gobies, banded coral shrimp, flamingo tongues
• Coral: Healthy hard coral coverage, gorgonian sea fans, giant barrel sponges, rope sponges in colors not seen on more pressured Bay Islands reefs

Schooling jacks and snapper at Roatan Banks: year-round

The schools of horse-eye jacks, cubera snapper, and Atlantic spadefish that stack on the Cocos Seamount at Roatan Banks are the visual signature of Cayos Cochinos. Numbers peak in the dry season (February through June), but the schools are there year-round. Currents along the seamount draw nutrients up the structure, which keeps the fish dense.

Hawksbill and green turtles: year-round across the reserve

Hawksbill turtles are seen on most reef dives, feeding on the giant barrel sponges that grow throughout the reserve. Green turtles are common in the shallow sandy areas around Lion's Head and the inshore reef sections. Both species nest on the cays during summer months, and the marine reserve actively protects nesting beaches.

The reserve is managed by the Honduras Coral Reef Fund (HCRF) with strict no-fishing, no-touch, and mooring-only rules. The per-diver park fee (typically $5 – $10 USD for foreign divers) funds enforcement and ongoing reef monitoring. The no-fishing protection has produced one of the most effective marine reserves in the Mesoamerican Reef system, and ongoing research collaborations with the Smithsonian Institution and Operation Wallacea have helped document healthy fish populations and reef recovery since the mid-1990s.

Practical information for diving in Cayos Cochinos

Practical information for diving in Cayos Cochinos is unusual compared to other Bay Islands destinations. Almost nobody stays on the islands themselves — the diving is reached via day trips from the mainland or Roatan, or via liveaboard. The booking model and the day-of logistics shape how the trip works.

Getting to Cayos Cochinos

Three practical routes:

1. Mainland day trip via La Ceiba or Sambo Creek. Fly into La Ceiba (LCE), transfer 25 minutes to Sambo Creek, board a small boat (panga) for a 40-minute to 1-hour crossing. Day-trip operators run daily in good weather. Cheapest option.
2. Roatan day trip. Several Roatan operators run dedicated Cayos Cochinos day trips. Crossing takes 1.5 hours each way, so dive time on-site is limited. More expensive but easier if you're already on Roatan.
3. Liveaboard. A few Honduras liveaboards (including Roatan Aggressor) include Cayos Cochinos as part of multi-day Bay Islands itineraries. The most thorough way to dive the area, since you can hit multiple sites over multiple days.
