Dr. Wilkenson’s, Calistoga CA

Both a spa and a resort and just a 1 hour 15 min drive from Marin. I was only able to go to this resort because a friend won some spots. but it’s amazing whether you spend the night or four hours. the mud baths and natural hot springs are so restorative and the resort restaurant makes a great green chili burger. I went in December and swam outdoors in the saltwater pools between the rains.
