Idaho is underrated as a dispersed camping destination. Roughly 63 percent of Idaho is public land - national forests, BLM, and state land combined. The Frank Church-River of No Return Wilderness alone is 2.4 million acres, the largest contiguous wilderness area in the lower 48 outside Alaska. Idaho also has more accessible dispersed hot springs than any other western state - dozens of geothermal pools reachable by forest road, many with dispersed camping directly alongside them.
Idaho's national forests
Sawtooth National Forest and Sawtooth National Recreation Area (Stanley area)
The Sawtooth Range - over 40 jagged granite peaks above 10,000 feet surrounding Stanley at the headwaters of the Salmon River - is Idaho's signature landscape. The Sawtooth NRA surrounding the wilderness has extensive dispersed camping on forest roads, particularly along the Salmon River east of Stanley (Hwy 75 corridor) and the forest roads north toward Obsidian. Important distinction: the Sawtooth Wilderness itself requires a free self-registration wilderness permit. The surrounding NRA and national forest land does not. Season: July through September. The Salmon River hot springs near Sunbeam are within the NRA - free dispersed camping alongside hot pools at road's edge. Cell service essentially absent east of Stanley.
Payette National Forest (McCall area)
Central Idaho's primary national forest, bordering the Frank Church Wilderness on the east. The Payette NF is the gateway to river access for the Middle Fork and Main Salmon River. Forest roads off Hwy 55 and Hwy 95 north of McCall give access to dispersed camping throughout. The Secesh River area east of McCall (FR 674) has dispersed camping alongside a free-flowing river at 5,500 to 7,000 feet. Season: June through October at lower elevations, July through September at higher. Hot springs: Burgdorf Hot Springs north of McCall is a fee facility, but several dispersed hot springs along forest roads in the area have free soaking.
Boise National Forest (Boise area)
Closest national forest to Boise, covering the mountains north of the city from the Boise Front to the Middle Fork Payette River. Forest roads off Hwy 21 (the Ponderosa Pine Scenic Byway) north of Boise provide dispersed camping within an hour of the city. Lowman Ranger District has excellent forest road camping around the South Fork Payette River. Hot springs: Kirkham Hot Springs near Lowman on Hwy 21 has a developed fee pool, but undeveloped soaking spots exist upstream and downstream on the river - free, dispersed, with camping nearby. Season: May through October at middle elevations.
Caribou-Targhee National Forest (Idaho Falls area)
Eastern Idaho's national forest, sharing the Teton Range with Wyoming and Grand Teton National Park. The west side of the Tetons - entirely within the Caribou-Targhee NF - is the Idaho alternative to Grand Teton. Dispersed camping on forest roads with comparable mountain terrain and no entrance fee. Season: July through October. Black bear and grizzly country near the Wyoming border. Access from Driggs or Victor on Hwy 33.
Idaho's dispersed hot springs: the unique opportunity
Idaho's geothermal activity has produced dozens of accessible hot springs on public land, many reachable by forest road with free dispersed camping alongside or nearby. This combination - free camping plus free hot springs with no developed facilities - is rare even in the western states.
- Sunbeam Hot Springs (Custer County). On the Salmon River east of Stanley via Hwy 75. Natural hot water flows into the river creating soaking spots at various temperatures. Free, on national forest land, no permit required. Dispersed camping on both sides of the highway along the river corridor. Year-round access; best in spring and fall when river flow moderates the temperature.
- Pine Flats Hot Springs (Valley County). South Fork Payette River near Lowman on Hwy 21. Multiple dispersed soaking spots along the river bank with camping nearby. Free, on Boise NF land. Accessible May through October; road can be muddy in early spring.
- Goldbug Hot Springs (Lemhi County). South of Salmon off US-93 via a short but moderately steep 2-mile hike. Multiple tiered pools at different temperatures. Free, on BLM land. Dispersed camping in the lower area near the trailhead. One of Idaho's more photographed hot springs - expect crowds on weekends.
- Council Mountain Hot Springs (Adams County). North of Council via FR 091. More remote, fewer visitors. Dispersed camping nearby on Payette NF land. High-clearance recommended. Best May through October.
Use the Find Land tool to confirm whether hot spring access land is public before hiking to any spring in Idaho - some are on private property and the trailhead access has changed in recent years.
BLM land in Idaho
Idaho's BLM land is concentrated in two areas: the high desert Snake River Plain in the south (Twin Falls, Boise, and Magic Valley areas) and the canyon country along the Snake River. The Owyhee Mountains in southwest Idaho (Owyhee County) is some of the most remote BLM land in the lower 48 - vast canyon terrain with essentially no services or visitors. Standard BLM 14-day in 28-day rule applies throughout.
The Craters of the Moon National Monument and Preserve (Butte County, off US-20/26/93) has BLM-managed land adjacent to the monument with dispersed camping. The lava field terrain is unique in Idaho - camping on lava requires extra attention to tent site selection and footwear. Season: May through October.

Idaho dispersed camping rules
- Stay limits. National forests: 14 days. BLM: 14 days in 28-day period, relocate 25 miles.
- Fire restrictions. Check the specific ranger district and the Idaho Department of Lands (idl.idaho.gov) for current restrictions. Idaho has significant fire risk in August and September.
- Bears. Black bears statewide. Grizzlies near the Wyoming border (Teton and Caribou-Targhee NF areas, Frank Church Wilderness edges). Bear spray and food hang required throughout - canister required in some Sawtooth Wilderness areas.
- Hot springs etiquette. Soak only in natural hot water flowing into pools. Never put soap, shampoo, or sunscreen into a hot spring - the microbial ecosystems are sensitive and soap kills them. Pack out all trash.
- 200 feet from water. Required on all federal land. Hot springs are water sources too - camp 200 feet from the spring outlet.
For dispersed camping rules generally, see the dispersed camping guide. Use the Find Land tool to confirm public land status in Idaho before camping, particularly near hot springs where private inholdings are common.
