Las Baulas has only 500 hectares of land but has 22,000 hectares of ocean area. Grande Beach is included in the park as it is the one of the largest nesting sites for the leatherback sea turtle (Dermochelys coriacea) in the World. Its 600 hectare mangrove swamp contains all six of the mangroves known along the Pacific Coast.

There are no accomodations within the park but plenty of hotels, guesthouses and restaurants in Tamarindo, right on the edge of the park.
