Santa Rosa National Park
This national park protects both historical sites and tropical dry forest. In March 1856, the Santa Rosa battle was fought here, when a group of filibusters commanded by American mercenary and politician William Walker were trying to conquer Central America and entered Costa Rica from Nicaragua.
A battle arose on the lands of Santa Rosa, and the Costa Rican troops defended the country’s independence. The Santa Rosa National Park protects a wide variety of animal species, some of them endangered. Nancite beach, along with Ostional, hosts the largest "arribadas" in all of tropical America, where sea turtles come to nest on the beach.
