[3][4] The main entrance of Santa Rosa National Park is 36 kilometres (22 mi) north of Liberia on Route 1, in northern Guanacaste Province.

It is part of the Area de Conservación Guanacaste World Heritage Site, originally created to protect the scene of the Battle of Santa Rosa.

Primarily, Costa Rica remembers the Battle of Santa Rosa won by their army over the forces of filibuster William Walker.

On March 20, 1856, when the Costa Rican forces reached this point, the filibusters were housed in the main farm building, La Casona.

[citation needed] Two Ramsar sites are located within the park, Laguna Respringue and Manglar de Potrero Grande.
