You push off from the skiff and the Pacific pulls at the hull—salt on your lips, wind flattening the bay. The Marietas Islands rise like dark bones off the Nayarit coast: volcanic rock scarred by sea and time, cliffs perforated with caves and tunnels that invite exploration.

You push off from the skiff and the Pacific pulls at the hull—salt on your lips, wind flattening the bay. The Marietas Islands rise like dark bones off the Nayarit coast: volcanic rock scarred by sea and time, cliffs perforated with caves and tunnels that invite exploration.
Formed by submarine volcanic eruptions, the Marietas are a protected national park and bird sanctuary. Jaques‑Yves Cousteau helped put them on the map; today the islands shelter coral gardens, sea caves, and abundant reef life shaped by the mixing of open‑ocean and bay waters.
Divers can expect two guided immersions from a shared skiff, typically a 4‑hour outing from Sayulita/Punta de Mita. Depths commonly range from shallow reef swims to 20–30 meters on deeper sites around pinnacles and lava flows. Visibility is often excellent—calmer mornings yield the clearest water—while currents can shift, so guides plan routes to match conditions.
Practical pointers: bring proof of certification if you’re a certified diver; beginners can join guided shallow dives or snorkel. Don’t fly within 48 hours after diving. Use reef‑safe sunscreen, secure loose gear, and follow the guide’s brief on buoyancy to avoid contact with fragile coral.
The islands reward steady attention: schools of tropical fish, turtles moving like slow commas, the occasional eagle ray arching past. Respect the park rules—landing is restricted and permits are enforced—to keep this compact marine world healthy for the next dive.
Certified divers must show proof of Open Water (or higher) certification; non‑certified guests can often join guided shallow dives or snorkel options—check operator requirements.
Sites around the Marietas include shallow reef swims and deeper walls/pinnacles that commonly reach 20–30 meters; specific depths depend on the chosen dive sites and conditions.
Access to the Hidden Beach is managed by park authorities and can be seasonally restricted for wildlife protection; landing is not guaranteed and may be subject to permits.
Trips are often cancelled for unsafe sea conditions; operators typically refund or reschedule tours if the operator cancels due to weather or insufficient travelers.
