Nimrod Hot Springs is a primitive geothermal site in the Flint Creek Valley west of Philipsburg, Montana. The spring emerges at around 43°C and flows into a small developed pool. Tall grass and willows surround the site, which sits a short walk from the forest road. It attracts visitors looking for a no-frills natural soak away from commercial facilities, and its secluded valley setting provides birdwatching and wildlife viewing as a bonus.
