Description - The second largest wilderness in California, this area was formerly the Salmon Trinity Alps Primitive Area, and was nearly doubled in size to 513,100 acres by the 1984 California Wilderness Act. Rugged and isolated, this wilderness consists of mountain ridges and deep canyons between the Trinity and Salmon Rivers and overlaps from the Klamath into Trinity National Forest. The area is host to more than 55 lakes and streams, scattered timber stands, large meadows, barren rock cliffs, and high peaks. Elevations within the wilderness range from 2,000 to 8,000 feet. Bear and other wildlife are plentiful.
- There are many trails in the area. Some of the most heavily used are those which lead into the Canyon Creek, Stuart Fork, Swift Creek, and Grizzly Creek drainages. Less used areas include those south of Coffee Creek Road and near Little Mill, Washbasin, and West Boulder lakes. Visitor permits are required.
Firewood is scarce in many areas and camp stoves are recommended. Forage is limited; stock feed is required before July 1.
Recreation - Opportunities for hiking, backpacking, and fishing abound in the Trinity, home to the Trinity Alps and more than 55 lakes and streams.
Climate - As in most parts of the Klamath National Forest, the climate throughout the Trinity Alps Wilderness Area is influenced by elevation. Most of the precipitation comes between November and April. This comes in the form of rain at the lower elevations and some wet, heavy snow in the higher elevations. The annual precipitation is 50 inches, including up to 12 feet of snow. April through October are normally dry, with warm temperatures at the low elevations and moderate temperatures in the higher elevations. The area is accessible from mid-June to mid-October.
Located on the southern border of Klamath National Forest near the town of Yreka in northwestern California. Also spills into Six Rivers National Forest which is accessed via Eureka, Ca.
