Ninemeyer Hot Springs

- River ford at low water; the pools sit on the far bank, beside Ninemeyer Campground
- Accommodations
- No lodging; Ninemeyer Campground sits beside the springs, and other campgrounds and primitive sites dot the Middle Fork Boise River corridor
Ninemeyer Hot Springs is a late-season-only proposition on the far side of the Middle Fork Boise River: rocky, user-built pools with sand and rock bottoms that sit submerged or unreachable for most of the year. The access window is small — fording the river is only advised at low water, usually late July through November — and on multiple documented visits the pools were only ever seen steaming from the wrong side of a swollen river.
Pool Condition
Small, shallow soakers form along the river’s edge just below the source when the water drops. Clarity is hard to judge because the pools spend so much of the year underwater. Expect to build or rebuild your soak on arrival.
Seasonal Notes
Ford only in low-water, late-season conditions — roughly late July to November. Most roads into the Atlanta area close in winter, and the Middle Fork Boise River Road is heavily washboarded year-round.
Camping
The springs sit right next to Ninemeyer Campground, with plenty of other National Forest campgrounds and primitive sites along the Middle Fork Boise River Road.

Frequently Asked Questions
When can you soak here?
Only in low water, usually late July through November. For most of the year the pools sit submerged or out of reach across a swollen river.
How hard is the access?
The pools wait across the Middle Fork Boise River, reached by a ford that is only advised at low water. Expect to build or rebuild your soak when you arrive.
How hot is the water?
Not documented. The listing records no water temperature for Ninemeyer, so any figure found elsewhere is not verified.
What does it cost to visit?
The listing states no fee for the spring or for the campground beside it, and no official source publishes one. Not verified.
Can I camp nearby?
Yes. Ninemeyer Campground is right next to the springs, and the Forest Service notes the campground currently has no amenities and no developed campfire rings after wildfire damage. More campgrounds and primitive sites line the corridor road.
Is the campground the same thing as the spring?
No. The campground and the spring are neighbors at essentially the same spot on Forest Service Road 268. The campground's post-fire condition says nothing about the riverbank pools across the ford.
