Siskiyou Wilderness

Rain falling in the Siskiyou Wilderness (from 40" on lower eastern slopes to 200" on the high western slopes) drains into three watersheds: the Smith, Klamath, and Illinois Rivers. The Siskiyou Wilderness is unique in that some parts can be accessed year round in the lower elevations, providing opportunities for recreation not found elsewhere. July through mid-October is the best time to travel in the wilderness, although severe weather can occur in any month. Access to some trails may be restricted to summer months because of snow and/or seasonal road closures to prevent the spread of Port-Orford-cedar root disease. Summer temperatures can reach into the 90s.
