Isla San Lucas National Park

Welcome to a national park that’s infused with history, which didn’t gain its designation as a national park until September 2020, since it used to be one of the country’s wildlife refuges.

Isla San Lucas is known for its history as a prison, a role the island served from 1873 and 1991. After it was closed, it first became a wildlife refuge before being converted to a national park. That was how it went from being a prison to its current status as a historic and tourism center.

The island is located in the Gulf of Nicoya, some 8 km from Puntarenas. It has an area of 472 ha and altitude ranging from 0 to 220 masl.

The region has two markedly different seasons: the dry season, from December to April, and the rainy season between May and November.

The island has also inspired a number of literary works, including a novel entitled La Isla de los Hombres Solos (The Island of Lonely Men, published in English as God Was Looking the Other Way). by José León Sánchez, and the short story La Ventana (The Window) by Carlos Salazar Herrera.
