Dive Areas in the Hammerhead Triangle
Malpelo Island
The 300-kilometer (190-mile) submarine ridge, that Malpelo Island is part of, has never been connected to the mainland and has some of the deepest waters in the world.
Marine Life
Malpelo Island is home to a massive shark population; walls of hammerhead sharks are sure to be seen as well as large schools of silky sharks. Their prey is just as impressive. Bigeye trevally, red snapper, barracuda, yellowfin tuna and amberjack cruise around in these protected waters.
Malpelo Island is one of the few places where the small-tooth sand tiger can be seen and the Malpelo barnacle blenny is also unique to this area.
Whale sharks are often spotted north of the island.
Best Time to Dive in Malpelo Island
Malpelo Island’s tropical climate lends itself to all-year-round diving. If you want to see hammerheads and the small-tooth sand shark, the best time to dive Malpelo Island is from January to May. Although it may be sunny, the dive conditions are more difficult, with rougher seas and cooler waters, with shallower thermoclines.

Marine Life in Coco’s Island

The rich and extensive reefs in this diving paradise attract big schools of bigeye trevallies, blue striped snappers, and other schooling fish. It’s the ultimate destination if you get excited about oceanic pelagics.
Best Time to Dive in Coco’s Island

Galapagos Islands
The unforgettable Galapagos Islands are, for many divers, the ultimate diving destination. This remote archipelago offers plenty of marine and wildlife and is known as one of the best liveaboard destinations in the world
Marine life in the Galapagos Islands
While diving, you could see sea lions, eagle rays, marine iguanas, penguins, seals, hammerhead sharks, Galapagos sharks, sea turtles, golden rays, whale sharks and tuna.
Best time to Dive in the Galapagos Islands
There is no bad time to visit the Galapagos Islands and diving is possible all year.
June through December are the cool and dry months and is also whale shark season. The nutrient-rich currents bring them, and other large marine life, to the islands. This season is also great for penguin-spotting.
January through May are warm and wet and the best season for shark action, including walls of hammerheads and other sharks. The conditions are generally better with calmer waters, milder currents, and better visibility.
