Isla del Coco

Thirty-six hours by boat to an uninhabited island where hammerhead sharks school in hundreds.

#Water#Solo#Friends#Adrenaline#Unique

The first thing you notice is the silence — 550 kilometres of open Pacific between you and the nearest land, nothing but the creak of the liveaboard and the deep blue dropping away beneath the hull. Then you descend, and the silence fills with hammerheads. Hundreds of scalloped hammerhead sharks circle the seamounts of Isla del Coco in Costa Rica, their silhouettes darkening the water column like slow-moving storm clouds.

Isla del Coco is a UNESCO World Heritage Site and one of the most remote inhabited islands in the Eastern Pacific. The 36-hour voyage from Puntarenas delivers divers to a volcanic island with no permanent residents, no airstrip, and no accommodation on land. Jacques Cousteau documented the island's underwater life in the 1990s, and the dive sites bearing his name remain benchmarks for pelagic encounters. Whale sharks, manta rays, tiger sharks, and dense schools of silver jacks share the same water on a single dive. Above the surface, the island's waterfalls plunge directly into the sea through jungle that has never been cleared.

Solo

Ten days on a liveaboard with a rotating crew of divers strips away everything except the ocean. This is the kind of solitary immersion that resets a person.

Friends

A liveaboard trip with a tight group becomes a shared expedition — three dives a day, galley meals, and evenings spent reviewing footage of what swam past you.

Why This Place
  • The island sits 550km from the mainland — reachable only by a 36-hour live-aboard dive vessel — and no overnight land-based accommodation exists.
  • Scalloped hammerhead sharks school in groups of hundreds around the seamounts here — one of the only places on Earth where this occurs predictably.
  • Jacques Cousteau called Isla del Coco 'the most beautiful island in the world' — the dive sites named after him remain the benchmark for Pacific pelagic diving.
  • Whale sharks, manta rays, tiger sharks, and silver jack schools share the same water column on a single dive — biodensity unmatched in the Eastern Pacific.
What to Eat

Meals served on the liveaboard dive boat — fresh-caught tuna sashimi between three daily dives.

No restaurants, no shops — just the galley cook and whatever the Pacific provides.
