Welcome to Palmer Mountain and Split Rock Recreation Sites!
Palmer Mountain Management Area comprises more than 6,500 acres of public land and is managed by the
BLM. It is a great place for hiking, backpacking, camping, horseback riding, hunting, mounting biking, and
fishing at tiny Washburn Lake. The autumn is especially picturesque when the many stands of aspen trees
create a brilliant yellow and orange background. Visitors are sure to find a favorite spot to enjoy the quiet, scenic
views of the Okanogan hillsides, aspen tree groves, grasslands, and the serene waters of Washburn Lake.
