Palmer Mountain

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, dispersed 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.
