About Phantom Falls
Phantom Falls is a seasonal cascade tucked into the foothills of the Sawtooth National Forest and managed by the U.S. Forest Service. The falls are at their most dramatic in spring or after heavy rains, when runoff brings the cliffside stream to life; during dry summer months the flow can be reduced or intermittent. The setting feels pleasantly remote yet reachable, making Phantom Falls a rewarding goal for hikers who want a scenic payoff without a full-day commitment. Access is via the USFS PHANTOM FALLS TRAIL (Trail #7245). The route is commonly described as a moderate, out-and-back outing of about 2.0 miles with roughly 300 feet of elevation gain (the USFS GIS record for the trail lists 1.47 miles). The trail threads through mixed forest and open stretches, and Bostetter Campground sits about 8.9 km away for those who want to make an overnight trip of it. Expect birdlife, quiet forested sections, and a short scramble near the viewpoint—perfect for photographers and anyone chasing seasonal waterfalls.
The Setting
Phantom Falls sits at 6,375 feet within Sawtooth National Forest, fed by the Goose Creek, in the high mountains of Idaho.

PHANTOM FALLS TRAIL (Trail #7245) — USFS-managed in Sawtooth National Forest. Trail class: 2. Surface: native material. Typical grade: 5–8%. Official/tracked length: USFS GIS 1.47 miles; commonly listed trail length 2.0 miles (out-and-back). Elevation gain: ~300 feet. Difficulty: moderate. The route is an out-and-back that follows native-turf tread through forested and open terrain. With a typical grade of 5–8% the hike is steady but not steep; tread is natural and can be uneven or muddy after rain, so good trail shoes are recommended. The lower technical demand (Class 2) means hikers may encounter short, non-technical scrambles near the viewpoint but no sustained climbing. Plan for seasonal waterflow at the falls (peak in spring/after heavy rains) and note nearby Bostetter Campground ~8.9 km away for camping.

Visitors can expect a peaceful hike with scenic views of the surrounding landscape. The waterfall itself may vary in flow depending on the season, and the area is relatively undeveloped, offering a more natural experience.
