About Barth Hot Springs

Barth Hot Springs delivers a raw, natural soak beside the rushing Salmon River in Idaho County. Its warm, mineral-rich waters invite you to unwind amid untouched wilderness, blending soothing comfort with rugged surroundings. The spring’s primitive charm keeps you connected to nature’s rhythms.

Getting There

Reach Barth Hot Springs via a short 10-minute walk from a small parking area, tucked just off a forest road. Parking is limited, so arriving early helps secure a spot. The trail is easy enough but may be muddy or uneven, reflecting the wild Idaho swimming holes it leads to.

What to Expect

Expect warm, inviting waters that soothe tired muscles, with views of dense trees and the river’s steady current creating a peaceful atmosphere. The spring is clothing optional, adding to the unstructured, natural vibe. Facilities are minimal—this is primitive soaking at its purest, with occasional visitors but no developed amenities.

Tips for Visitors

Visit year-round, mindful that weather shifts quickly in this region. Bring sturdy footwear for the walk, plenty of water, and a towel. There’s no fee, but pack out all trash and respect the quiet setting to keep the spring pristine for others who seek out these Idaho hot springs.
