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.

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.
