This wellness resort's hot mineral springs bubble up into private outdoor tubs on an oak-and-sycamore-forest hillside. Whether or not you stay here, it's worth coming for a soak—even though the grounds are well within earshot of a busy road. Each room or suite has its own private balcony with a hot tub; about half have mineral water piped in. The spa offers everything from massages and skin care to yoga classes and a variety of integrative healing arts. Creative spa
and California cuisine is served in the romantic Gardens of Avila restaurant ($$–$$$).
