Keough is one of the best spots in California for camping and hot springs. The resort was established nearly 100 years ago (1919). Keough is quaint and more for RVers than 5-star travelers.
One of the most upscale resorts on our list, the Fairmont Sonoma Mission Inn has a championship golf course, fantastic restaurant, and of course, the hot springs. The resort opened in 1927. It is a pretty cool switch-up on a trip to wine country.
Sierra Hot Springs is a getaway for nature lovers, and it is acceptable to go "au naturale". The resort offers lodging and camp sites, along with spa services.
Glen Ivy Hot Springs is in Corona, which is an hour east of Los Angeles. Glen Ivy has top-notch facilities. The grounds are beautiful, the restaurant is great, and the spa offers some very unique services. The only reason that Glen Ivy didn't rank higher on our list is because they have recently received pretty consistent service complaints on online forums.
Mono Hot Springs may be the best on our list for outdoors enthusiasts. The resort is on the San Joaquin River and there is plenty of excellent hiking and fishing in the area. The resort was built in 1935, and many of the cabins still carry the decor from several decades ago. However, that is part of the charm and you can still get a meal at the restaurant and a massage at the spa.
Sitting halfway between San Francisco and Los Angeles is Paso Robles, home of River Oaks Hot Springs Spa.

Vichy Springs is one of the most unique on the list. The resort was established in 1854, and it is the only naturally-occurring warm and carbonated hot springs in North America. The hotel is pretty basic, but if you're looking for more extravagant accommodations, consider visiting #1 on our list.
