Open Meadow near El Capitan

Situated in the far northwestern corner of California, the Siskiyou Wilderness protects 182,802 acres of craggy peaks, forested ridges, deep glacier carved canyons and some of the most botanically diverse coniferous forests on the planet.

While not particularly high by most standards, don't be fooled into thinking these mountains are insignificant. What they lack in elevation, they make up for in relief, the Siskiyous are a very rugged range of mountains. This is especially true Siskiyou Wilderness. Elevations range from 700 feet near the mouth of Clear Creek to 7309 on the summit of Preston Peak. The wilderness sits on three national forests namely the Six Rivers, the Rouge River-Siskiyou and the Klamath.

Although the Siskiyous do not exceed timberline, the range features many qualities one would expect to find in a true alpine range. Many areas show significant signs of glaciation, as evidenced in the many glacial lakes and barren rock exposures.

This is remote country, quite possibly the least visited chunk of mountains in California, but this is difficult to verify because the forest service doesn't keep track of visitation. The degree of solitude that can be found here is unparalleled, you can walk for days and not see a single trace of human presence besides a fleeting overgrown trail that fades in and out of the brush.

Most use is concentrated to the northwest corner of the wilderness, few of the trails found elsewhere are maintained on a regular basis. Large tracts of the wilderness are completely lacking in trails, especially in the southern reaches. Off trail travel can be a battle due to dense brush and unstable slopes.

Geography / Geology

The Siskiyous are a part of the greater "Klamath Mountains". This name however mostly exists in guidebooks and a small selection of maps. Most Locals Know the names of the individual ranges but the collective term is largely unknown.

Rocky Knob over Youngs Valley

Many guidebooks make the claim that the Klamaths were once connected to the Sierras, only to be separated by lava flows from the nearby Cascades. Though the glaciated granite portions of the Klamaths do bare a striking resemblance to the Sierras this assertion is completely false. The Klamaths are a folded anticline that rose from the sea. As a result the geology of the area is complex and varied. Large areas of mantle rock came to the surface leading to the numerous serpentine outcrops. Most of the wilderness north of Youngs valley is composed of mantle rock.

Other types of rocks common to the area are peridoite and some granite. South of youngs valley these two rocks alternate along the crest.

The OceanThe ocean viewed from the trail to Summit Valley

The Siskiyous are the largest subrange by area in the Klamath Mountains. They form two main crests, the first trending south to north from the town of Wichepec on the Klamath river to Oregon Caves National Monument. From Here the range bends and runs west to east, roughly along the California/ Oregon border until it merges with the Cascades.

Devils Punchbowl

Most of the north south trending crest is within the Siskiyou Wilderness. Some of the most rugged and remote territory in California can be found here. Due to its proximity to the ocean this area was hit much harder by the last ice age than the rest of the Siskiyous, making the effects of glaciation a lot more obvious.

Preston RidgeNortheast corner of the wilderness from Summit Valley Mountain

The wilderness is home to hundreds of glacial tarns ranging in size from a small puddle to deep mountain lakes. The headwaters of several major rivers begin here in classic glacially carved U shaped canyons.

The higher ridge tops get up to 200 inches of precipitation a year. This is in sharp contrast to the 50 inches that fall on the lower eastern side. The range of precipitation coupled with the unique geology makes this area home to some of the most botanically diverse coniferous forests on the planet.

Long before Europeans arrived here the Yurok and Karuk tribes have considered the high country to be the center of the spiritual universe. Today local Indians still practice spiritual activities around Sawtooth Mountain. If you see any of them it is considered polite not to approach or speak to them.

Intrusive activities were generally limited due to the extremely rugged character of the land. Some mining roads were built but the higher country was never exploited like the lower surrounding hills.

The Ridge
Northwest ridge of Preston Peak

In the early 80s a the forest service began a radical project, a high quality ridge top road that would link the communities of Gasquet and Orleans. Once completed the road was supposed to create a boom for both communities with increased timber revenues. The road was nicknamed the "GO road", an abbreviation for Gasquet-Orleans. As the project neared completion several groups filed lawsuits over the environmental impact of such a road. The final link of the road was never paved, and with the 1984 designation of the Siskiyou Wilderness it never will be. Today these roads on either side of the wilderness still exist and seem bizarrely out of place for this remote area.

Siskiyou Wilderness From Ship Mountain


One best features of the Siskiyou Wilderness is the abundance of mountain lakes found here. Most lakes were formed from glacial activity during the last ice age, giving them many alpine characteristics. Listed here are the major lakes that are accessible by trail. The wilderness is home to many more lakes not listed here, most of which require significant off trail bushwhacking to reach.

Name Location Description Photo
Kelly Lake .5 miles from Kelly Lake TH Located only .5 miles from the trailhead, Kelly Lake is the most popular destination in the Siskiyou wilderness. Most visitors come for short day trips. Fishing is a popular activity here.
Kelly LakeKelly Lake (Zach Urness)
Lieutenant Lake Various distances, Young's valley TH, Black Butte TH, Poker Flat TH Far away from any trailhead, this remote lake is set in a cirque beneath the towering Lieutenant Peaks. Regardless of which trailhead one begins from, reaching this lake will require crossing two mountain passes, meaning solitude is pretty much a guarantee here. The lake is unofficially named on the topo, and is known to some as Private Lake.
Lieutenant LakeLieutenant Lake
Sanger Lake Just outside the wilderness boundary on Road 18N07 Located a stones throw outside the wilderness boundary, Sanger Lake offers a lot of the qualities one would expect to find at the lakes within the wilderness, but without the hike. The lake is popular with fishermen.
Sanger LakeSanger Lake
Raspberry Lake 7 miles from Young's Valley TH Set beneath the dramatic Preston Peak, this deep mountain lake is one of the most scenic in the wilderness. The lake is packed with trout and offers some of the best fishing in the wilderness as well. The hike in follows an old road bed most of the way.
Raspberry Lake is pristine...Raspberry Lake (Dennis Poulin)
Devil's Punchbowl 6.5 miles from Doe Flat TH The crown jewel of the Siskiyou Wilderness, Devil's Punchbowl is set in a deep u-shaped glacier carved valley. Steep granite walls shoot thousands of feet directly up from the lake. The lake has little vegetation to use as firewood, so be sure to bring a stove. Despite the strenuous hike required to get here, this is one of the most popular destinations in the wilderness. Solitude is not a guarantee on summer weekends.
Devil s PunchbowlDevil's Punchbowl
Buck Lake 1.5 miles from Doe Flat TH A quick stroll from the Doe Flat trailhead brings one to Buck Lake. While not nearly as scenic as its neighbor Devil's Punchbowl, Buck Lake is none the less a pleasant location. The lake is a popular destination for day trips.
Buck LakeBuck Lake
Island Lake 7 miles from Island Lake TH A steep hike gaining close to 3000 feet takes one up to scenic Island Lake. The lake sits in a granite bench near the summit of Jedidiah Mountain. Due to the strenuous hike required to get here the lake sees little use. The current trail begins by following an old roadbed top the south fork of the Smith River, then climbs into the wilderness though a burned out forest.
Island LakeIsland Lake (Zach Urness)
Bear Lake 3.2 miles from Elbow Springs TH Located on the eastern extent of the Wilderness, Upper and Lower Bear Lakes occupy a valley beneath Bear Peak. Views are sweeping for most of the hike in, and the lake offers fantastic camping. This section of the wilderness is seldom visited.
Lower Bear LakeLower Bear Lake (Zach Urness)
Harington Lake Various distances, South Kelsey TH, Elbow Springs TH, Gunbarrel TH Situated near the geographic center of the wilderness the scenic Harington Lake is set beneath the granite cliffs of Harington mountain. Getting there requires a long hike from any direction, and the section of the Kelsey Trail from Bear lake to Eightmile creek has not been maintained in many years. But those willing to make the hike will be rewarded with some of the best and most isolated scenery the Siskiyous have to offer.  
Island Lake
Flat Iron Lake 2 miles from the Elk Valley TH Flat Iron Lake is the most notable of several tarns along the boundary trail. The lake is quite small and shallow, but carries a unique charm other lakes in the wilderness can not match. Most of the boundary trail is not maintained, and offers incredible potential for solitude to those with decent wilderness navigation skills.
