We stopped here on our way further west. There were 2 other campers there, but we were able to find a great spot where they couldn’t be seen.
Plenty of sites, ours was 1.5 miles off 191. Easy to get to in our 26’ bus. Saw a handful of vehicles pass by, likely on there way to Hot Wells.
The Hot Wells Springs were closed due to Covid, so I assume that limited a lot of traffic through Tanque Road.
At times of the year, locals probably use this as their own shooting range, as I saw plenty of casings. YMMV. It was gorgeous and peaceful for our stay.
