Sespe Hot Spring is my favorite backpack in SoCal and one of my favorite hot springs ever. This was my 4th time there by two different routes and it’s always a rejuvenating trip. I spent just one night there, soaking in the hot stream for many hours over the course of two days. I’d seen bighorn sheep here before, this time I shared the small valley with the largest band I’d ever seen. About 30 sheep including two rams and many young. I’m already looking forward to my next visit. The day before Sespe I cycled up Warm Springs Mountain, a prominent peak north of Castaic Lake with an abandoned inmate rehab center at its base.
