This is a fantastic place with huge views of the Pueblo mountains as well as the Black Rock and Pine Forest mountain ranges. Sunsets are amazing here. We have been here before this latest time. I was reluctant to review or ID the place because it is such an awesome place or it was anyway. The first time we came here in 2018 we had the place to ourselves for hours and then just one other couple showed up. This latest time there were 3 fifth wheels, 4 RV's, 3 trailers, various other tent and truck campers. It was super crowded. So i guess the word is out. It is on google and noted in various books.
One sad note was as we walked around there was a fair amount of trash and toilet paper. It was incredible how much human poop was just left on the ground in the surrounding desert. Total bummer. Bury your stuff!
This place is located a few miles off Hwy 140 near the Sheldon Wildlife Refuge. The hot water actually flows down a creek from the spring. People have used rocks to make various pools and courses. The water is obviously hotter closer to the source but the main pool is right around 98 to 95 degrees. The temps vary along the creek. The camping is dispersed and primitive with no amenities what so ever. Pack in and pack it out.
