There are 3 pools at this location. Its an easy .3 mile walk down into the canyon, right next to the river with great views all around.
At the last switchback on Country Road B-007, is where the trailhead is located. if you've gone to the lowest point possible within the canyon, right next to the river, you have gone too far and need to turn around to the last switchback. it is an easy .3 Mile trail with a 68 foot elevation drop/gain.
The biggest, deepest, and greenish pool is the warmest out of the 3. If you need help getting here, I would suggest downloading the app AllTrails, where you can find the location and have it autoMatically pull the directions up on your phones GPS for you.
*Beware* this is a clothing optional Hot Spring, so you could encounter nude people.
