El Valle's northern edge is protected within the 827-acre (335-hectare) nature reserve Monumento Natural Cerro Gaital, which covers the hills of Cerro Gaital, Cerro Pajita, and Cerro Caracoral. Cerro Gaital is a steep, forest-draped hill that towers over the valley's northern edge, rising to a summit of more than 3,500 feet above sea level. The lush wilderness that covers it is home to more than 300 bird species, including such spectacular creatures as the red-legged honeycreeper, bay-headed tanager, and blue-crowned motmot. It also protects the habitat of the rare golden toad (Atelopus zeteki). The bird-watching is best along the edges of that protected area, since its lush foliage provides too many hiding places for those feathered creatures, and the terrain is dangerously steep. The areas around El Nispero, Los Mandarinos hotel, and the old Hotel Campestre are also excellent for bird-watching. There is a trail into the forest by the ranger post on the right, above the Refugio Ecológico Chorro Macho, approximately 10 km (6 miles) from the church. It requires good shoes and decent physical condition and is best done with a guide.
