Two coasts in one country: quiet Caribbean reefs at the Corn Islands and mass turtle nesting on the Pacific.

Why Nicaragua
Nicaragua has two very different seas. On the Caribbean side, the Corn Islands sit inside a protected marine area, with calm reefs, nurse sharks, eagle rays and turtles, and Little Corn has no cars. On the Pacific side, thousands of olive ridley turtles come to nest together on a few nights at two wildlife refuges, and humpback whales pass by San Juan del Sur in two seasons. The political situation is tense, some visitors are refused entry, and drones are not allowed at all, so Ocean Calling is only researching Nicaragua for now.
Conservation-led. Ocean Calling guests never chase, touch or bait animals.

Can we travel here ethically?
Ethics pass, with care
Good with the right operator. Here is how we choose.
Thousands of olive ridley turtles nest in protected refuges, but egg poaching continues, and there are not enough staff to guide all visitors on big nesting nights. On the Caribbean side, green turtles are still taken. There is no code for watching humpback whales here, so our own rules are the only standard. We are only researching Nicaragua, and we never buy turtle meat, eggs or shell.
Checked 30 Sep 2026. Places change, so we look again every year.

Where in Nicaragua
Short notes from our research. Wildlife is never guaranteed.
Corn Islands
ExploringTwo small Caribbean islands in a protected marine area, with quiet reefs and a car-free island for snorkelling and diving.
🤿 In the water: Reef fish and corals, Nurse sharks resting on the reef, Eagle rays, Turtles, Hammerhead sharks (rare, deeper sites)
⛵ From the boat or shore, never in the water: Bottlenose dolphins (occasional, from the boat)
When: Mar-May. Calmer, clearer water is most likely in April and May, and again from mid August to mid October, but that is hurricane season. From November to March the trade winds make the crossing rough.
San Juan del Sur and La Flor
ExploringA Pacific bay town near a small wildlife refuge where olive ridley turtles nest in large groups, with humpback whales passing offshore.
⛵ From the boat or shore, never in the water: Olive ridley turtles nesting at night (with refuge guides, red light only), Humpback whales (from the boat), Dolphins (from the boat)
When: Sep-Nov. Mass nesting can happen from about July to January, most often September to November, on a few nights around the moon. Humpbacks from the north pass January to April, and from the south July to October.
Chacocente
ExploringA dry forest refuge on the Pacific where thousands of olive ridley turtles come ashore to nest on the same few nights.
⛵ From the boat or shore, never in the water: Olive ridley turtles nesting at night (with refuge guides, red light only), Leatherback turtles (very rare, a few nests each year on this coast)
When: Aug-Nov. Mass nesting has been recorded from about July to December, with several events each season. The dates cannot be known in advance.
