Costa Rica has year-round warm water and plenty of broad, deserted beaches on both Pacific and Caribbean coasts.
Costa Rica's beaches rank among the best in the world. Two thirds of Costa Rica's borders are coastline, there are a whole lot of beaches to explore.
Nicoya Peninsula - which starts about 4 hours from San José.Montezuma is on the inner rim of the Gulf of Nicoya, crossing by ferry from Puntarenas. It is a popular destination for the younger foreign crowd. Costa Rica's largest peninsula is ringed by so many blissful strips of sand, it deserves a top ten list of its own. Besides livelier beach cities like Montezuma.Nicoya Península, Guanacaste's coast is divided by rocky points into dozens of beaches. Those on the Santa Elena Península are wild and isolated, visited only by adventurous nature lovers, dedicated surfers, and nesting sea turtles. The Gulf of Papagayo, to the south of that península, features more accessible beaches, many of which slope down into the tranquil waters of Culebra Bay.
Puntarenas is the old main port on the Pacific. It is a good point to start expeditions into Guanacaste and down the Pacific coast because there are ferries that take you across the Gulf of Nicoya here and onto the Nicoya Peninsula.the beach that stretches along the city is a bit urban, the coast by the mouth of the nearby Barranca River offers a more natural setting, and excellent conditions for surfing.
Tamarindo Beach North Pacific, one of the best surf and windsurfing spots, with good town facilities.Tamarindo's natural perks make the splurge worth it -- on the beautiful beaches adjacent to Tamarindo, giant leatherback turtles (and others) annually clamber ashore to lay their eggs.
South from Puntarenas about 1 hour, one can find Jaco Beach. This is a major tourist attraction for Costa Rican tourists and foreigners alike. Jaco is in such close proximity to San Jose. it flourishes with nightlife, international dining options, and even casinos.
