Near park headquarters (and just past the ranger station), this 800m trail has signs interpreting the ecological relationships among the animals, plants and weather patterns of Santa Rosa. You may see birds, monkeys, snakes and iguanas, as well as petroglyphs (most likely pre-Columbian) etched into rocks; also seen along the trail is the national tree of Costa Rica, the guanacaste.

The province is named after this huge tree, which is found along the Pacific coastal lowlands.

The trail is named after a common tree whose peeling orange-red bark can photosynthesize during the dry season, when the trees’ leaves are lost, resembling a sunburned tourist or ‘naked Indian,’ as the the trail name translates.
