Round the Bend Hot Spring is exactly what the name says: the steaming cliff face just around the bend from Ninemeyer on the Middle Fork Boise River. It is also, honestly, not a soak in the usual sense — there is no pool here at all. Hot water streaked with bright algae flows down a cliff straight into the river, and the only way to enjoy it is to wade in during late summer, when the river drops to about 3 feet deep, and find the seam where hot meets cold.
Description
A hot-water cliff seep rather than a developed spring: no pool, no dam, nothing built. The experience is standing or sitting in the river at the mixing zone — tricky to dial in, beautiful to look at, and unlike anything else on the corridor.
Seasonal Notes
Late summer is the only practical window, once the river is low enough to wade safely. Most roads into Atlanta close in winter, and the Middle Fork Boise River Road is heavily washboarded year-round.
Camping
Plenty of National Forest campgrounds and primitive sites are available nearby, including Ninemeyer Campground just around the bend.

Frequently Asked Questions
Is there really no pool?
Correct: no pool, no dam, nothing built. Hot water runs down a cliff face into the river, and you enjoy it by standing in the mixing zone where the hot seep meets the cold flow.
How do you reach it?
It sits on the Middle Fork Boise River Road (FSR 268) just around the bend from Ninemeyer Campground; the soak itself is in the river at low water.
When is the best time to visit?
Late summer, once the river drops to roughly 3 feet deep and can be waded safely. Roads into Atlanta mostly close in winter, and the river road is heavily washboarded all year.
How hot is the water?
Not documented: no temperature is recorded, and the experience is a mixing zone of hot seep water and cold river water.
Can I camp nearby?
Yes: primitive sites and National Forest campgrounds dot the corridor. The closest, Ninemeyer Campground, sits just around the bend and is currently listed by the Forest Service with no amenities after a wildfire.
