Vichy Springs Resort is located near Ukiah, CA and features hot springs. The trail is primarily used for hiking and is accessible year-round.
Vichy Springs is not only Jack London's favorite hot spot...it's one of mine too. I like it because of the low crowds, serenity, and natural hot springs. Or rather warm springs. Someday I'll get to hike the area. Last I went it was $50 a day pass.
GREAT TRAILS THROUGH OAK AND MANZANITA WOODLANDS AND A VERY BEAUTIFUL WATERFALL 1/2 HOUR FROM THE RESORT ON THE PROPERTY. BEAUTIFUL VIEWS FROM THE TOP BENCHES.
