Calistoga Ranch

Northern California has its share of upscale hotels, but this exclusive property—well situated among 157 acres of oak trees and burbling springs—is the epitome of luxury for West Coast nature lovers. Forty-eight freestanding guest lodges—all polished cedar and floor-to-ceiling glass—offer uninterrupted views of the trees and sky, both from their opulent, plush interiors and from their fire-warmed “outdoor living rooms” with private showers. The spa, situated among moss-covered boulders and mature trees, offers private mineral-soaking pools and outdoor mud baths; the Lakehouse restaurant, overlooking gleaming Lake Lommel, serves dishes using organic local produce; and yoga classes are held daily on a deck set high above the forest floor.
