Guanacaste National Park, National park in Guanacaste Province, Costa Rica.
Guanacaste National Park is a protected area in the northwestern province of Guanacaste, Costa Rica, covering a range of terrain from dry lowland forest to wet highland zones. The landscape shifts noticeably as you move through it, with different tree cover, soil, and wildlife appearing at different elevations.
The park was officially established in 1991 with the goal of linking already protected forest areas that had become separated by farming and land use over the decades. Before that, wildlife had difficulty moving between the dry and wet forest zones because of gaps in the forest cover.
The name Guanacaste comes from a large native tree that is also the national tree of Costa Rica, and you can spot these trees along the trails. Locals have a long relationship with this landscape, and that connection shapes how the park is managed today.
The dry season, which runs from December to April, is the most comfortable time to visit since trails are easier to walk and animals tend to gather near water sources. Some routes cover steep or uneven ground, so sturdy footwear is a good idea regardless of which trail you choose.
The park was designed not just to protect what was already there, but to allow cleared land to recover naturally over time by reconnecting it with intact forest. This makes it one of the few places where you can walk through forest that was once farmland, now slowly returning to its original state.
