San Juan Hot Springs adjacent to Highway 74 has seen better days. There is not too much left except for a couple of pools of hot steamy water. Back in the 60s and early 70s, San Juan Hot Springs was a hippie hangout. Before that, there were San Juan Capistrano Hot springs.
The original San Juan Hot Springs resort which was opened in the 1800s was abandoned in the 1940s. In the 1960s and 1970s is was a popular spot for locals to party and get high. The old-time comedian Red Skelton was evidently a regular along with every hippy in the area. From 1980 to 1992 the springs re-opened, but have been closed and in disrepair since. You can see the old entrance and sign (good for photos) if you hike a few minutes past the hot springs.
Today the hot Springs are accessible with a wilderness permit
The San Juan Hot Springs is located off Ortega Hwy Route 74 at the Hot Springs Canyon Rd and Sievers Canyon Rd exit. The hot springs is located down a trail. The hike takes about 5 minutes to get to the pools. You can also hike from Casper Regional Park and pay the $5 visitor fee and hike 5+ miles round trip to the hot springs.
