Capital of the Guanacaste province, Liberia is the gateway to Costa Rica’s most alluring attractions– white-sand beaches, turquoise waters, and volcanoes shrouded in rainforests. Visit Rincón de la Vieja National Park, just east of Liberia, with its plentiful forests and hiking trails. Travelers who visit the park can horseback ride, enjoy mud baths, or swim beneath waterfalls.
