Rancho La Puerta
A 3,000-acre property of landscaped gardens, organic farmland, and mountainsides crisscrossed by hiking trails surrounds this desert spa.
Signature Treatment: For the 45-minute Spring Rain Shower treatment, a detoxifying, full-body seaweed body mask is applied to re-hydrate and re-mineralize the skin. A gentle rain-like shower follows, to improve circulation (45 min, $85).
