Lower Salmon Falls Creek Wilderness Study Area


Lower Salmon Falls Creek Wilderness Study Area (WSA) is a 5.5 square mile Bureau of Land Management property that features a 16-mile long, 0.5-mile wide, and 300 to 600 feet deep canyon that dissects the Antelope Pocket lava plain. This wilderness area, which lies about 40 miles southwest of Twin Falls in Idaho, is a natural area that has very little human interference, making it a great setting for primitive camping and recreation. You will be able to access the wilderness from different areas, owing to the presence of access roads from the south, north, and east.

This WSA is home to diverse plant and animal species, as well as birds. As a result, nature observers, wildflower enthusiasts, birdwatchers, and wildlife viewers are attracted to the park. The canyon in particular is a good place for these recreational pursuits. In addition, guests can catch brook trout, smallmouth bass, and rainbow trout in the Creek. Upland and waterfowl hunting is open to interested campers too.

This BLM park is also a nice base camp for exploring nearby attractions such as Cedar Creek Reservoir, Salmon Falls Creek Reservoir, and Morley Nelson Snake River Birds of Prey NCA.

You can only camp in primitive sites in this BLM WSA, as no services or facilities are provided. Additional camping opportunities are available in Sawtooth National Forest.

Lower Salmon Falls Creek Wilderness Study Area lies about six miles east of Roseworth, Idaho. You can access this Bureau of Land Management area from the north by driving south of Castleford for about six miles on 900 East Road to Lilly Grade. If you want to access the southern end of the WSA, drive west from Rogerson for about 7.5 miles along Three Creek Highway.

The access routes that lead to the wilderness study area have a few undeveloped roads and passages that may require the use of high clearance vehicles. Moreover, the steep terrain of the BLM wilderness is a major reason why there are only a few routes to the park. Ensure you are well prepared for backcountry conditions as you make your way to the wilderness. It’s good to know what the terrain, weather, and physical road conditions are before you set out so you can be safe.


Room for parking vehicles is available for guests trying to make their way to the wilderness. You’ll find spaces to park before you arrive at the wilderness, as vehicles are not allowed within the WSA.
