Seasonal Notes
Submerges during spring runoff, accessible all year.
Camping Notes
Boise and Sawtooth National Forests and a popular campground is located nearby (within walking distance).


I was surprised to see anyone soaking this soon after spring runoff, but the horde of campers and soakers had diverted one of the main hot spring outflows to a channel large enough to pack in a dozen soakers on the bank opposite of the campground. I soaked only long enough to qualify, way too many people for my taste.

What an awesome day to visit an awesome hot springs! This was the first time I've been able to actually soak in Bridge, and was very happy to do so despite the crowds. The other soakers were friendly, and the area around the pools looked taken care of despite the high use. There is a nearby popular campground that supplies most of the soakers, the rest consist of locals and RVers. All in all, thumbs up.

Still too cool for a soak, but this time I got a picture (above). The forest road leading to Willow Creek Hot Springs was still closed.

Bridge gets it's name because it's located beneath both sides of a (get this) bridge that crosses the South Fork of the Boise River just before Featherville. I've been to this HS two times now, and each time the pools are far too submerged for soaking. Either that or new pools need to be reconstructed on higher ground. I have driven by in June and noticed quite a few kiddies hanging out by the pools on both sides of the bridge... the pools were still too cool for soaking.

No Soap, Shampoo or BIO-Soap/Shampoo Allowed in Hot Springs! Avoid Being Fined!

Public hot springs are not bathing facilities and do not have 'plumbing' like that of commercial, improved hot springs. Soap and shampoo (including biodegradable soap and shampoo) do not completely breakdown naturally. This pollutes our water systems (ingested by fish, animals, humans) at or near the source. This is also illegal in most wilderness and public lands areas.
