Machesna Mountain Wilderness


The 19,700 acre Machesna Mountain Wilderness became part of the National Wilderness System in 1984. The wilderness region is located in the State of California's, La Panza mountain range and contains chaparral, grasslands, oak woodlands, pine stands at higher elevations, and rugged terrain with rocky crags. A 1500 acre research area is part of the Bureau of Land Management wilderness and is preserved for the study of a strain of Coulter Pine that is present in the region. Elevations in the area range between 1600 and 4063 feet at the summit of Machesna Mountain. Magnificent views from the top of the mountain allow you to make out the snow-capped peaks of the Sierra Nevada in the distance.

American Canyon provides major drainage in the area that supports a variety of wildlife. Unique wildlife in the region includes the prairie falcon and tule elk. Recreational activities in the wilderness area include backcountry camping and hiking on the two major trails in the American Canyon and to the summit of Machesna Mountain. Temperatures in the daytime during summer reach 85 F and cool off significantly at night at the high elevations and during the winter freezing temperatures result in snow cover over the area so be prepared for temperatures fluctuations and frigid conditions in the offseason.

Nearby national and state parks within a couple of hours driving distance that make additional destinations for RVers include Los Padres National Forest to the south and Pismo State Beach to the west.
