Los Cusingos is the former farmstead of famed biologist Alexander Skutch, who settled the area in 1941. Only 15 visitors per day are allowed in the preserve, which represents about the last forested area remaining in the heavily agricultural San Isidro del General valley.
A highlight of any visit to Los Cusingos is sitting on the porch watching the hummingbird feeders. In addition, a trail through the forest along the Penas Blancas River allows visitors to see many of the forested birds in the area. Since the farmstead is south of the high Talamanca Cordillera, it attracts many of the specialty birds in southern Costa Rica that aren't found to the north.
