Things to do at the beach and in the water.
Surfing
Costa Rica has world-class surf on both coasts year-round. The Pacific coast offers more consistent waves with famous breaks at Tamarindo, Nosara, Dominical, Pavones, and Witch's Rock. The Caribbean coast has shorter seasons but barreling waves at Salsa Brava in Puerto Viejo.
Best at: Tamarindo, Nosara, Santa Teresa, Dominical, Pavones, Playa Hermosa (Jacó)
Snorkeling
Costa Rica's clearest waters for snorkeling are on the Caribbean side at Cahuita National Park's coral reef and at Playa Conchal in Guanacaste. The dry season (December-April) offers best visibility on the Pacific. Equipment rentals available at most beach towns.
Best at: Cahuita, Playa Conchal, Playa Flamingo, Isla del Caño (Osa Peninsula)
Whale and Dolphin Watching
Costa Rica is one of the world's best whale watching destinations with humpback whales from both hemispheres visiting. Marino Ballena National Park near Uvita and Drake Bay are prime viewing sites. Bottlenose and spinner dolphins are common year-round.
Best at: Playa Uvita, Drake Bay, Ballena Marine National Park (August-October best)
Sea Turtle Watching
Four species of sea turtles nest on Costa Rican beaches. Leatherback turtles nest at Playa Grande (October-March). Green turtles nest in massive numbers at Tortuguero (July-October). Olive ridley mass nestings (arribadas) occur at Ostional beach.
Best at: Tortuguero, Playa Grande, Ostional, Playa Camaronal
Stand-Up Paddleboarding
Costa Rica's calmer bays and estuaries offer excellent paddleboarding. Rent boards at resort beaches like Flamingo, Papagayo, and Manuel Antonio for open-water paddling, or explore mangrove estuaries on dedicated SUP tours.
