About Diria National Wildlife Refuge

Diria National Wildlife Refuge protects critical dry tropical forest habitat in northwestern Costa Rica, offering unique wildlife viewing and a tranquil experience for nature lovers.

Wilderness Landscape & Natural Heritage

Diria National Wildlife Refuge, located in the Guanacaste Province of northwestern Costa Rica, conserves one of the last remnants of dry tropical forest in the region. Spanning steep terrain and valleys within the Nicoya Peninsula, the refuge comprises a mosaic of dry forests, secondary growth, and small water bodies that support a variety of wildlife. Established to preserve vulnerable species and fragile habitats, the refuge is home to key mammals like white-tailed deer, peccaries, and howler monkeys, as well as a diverse bird population including trogons, parrots, and hummingbirds. The area experiences a marked dry season, which influences the vegetation and animal activity. Diria Refuge provides visitors an opportunity to explore this unique ecosystem through hiking trails and birdwatching spots. The refuge is less developed and less trafficked than Costa Rica’s more famous national parks, allowing for a quieter, more intimate nature experience. Visitors are encouraged to trek the refuge’s rugged paths to discover isolated viewpoints and spot elusive wildlife. The dry forest ecosystem is crucial for regional biodiversity conservation and offers a scenic backdrop of rolling hills, thorny shrubs, and seasonal streams. Diria also plays a role in local ecological education and community engagement, emphasizing sustainable land use and preservation. Visitors should prepare for conditions typical of dry tropical environments, with hot weather during the dry months and limited shade in some trail sections. Overall, Diria National Wildlife Refuge appeals to outdoor enthusiasts interested in birdwatching, hiking, and learning about lesser-known tropical forest types.
