Glen Ivy Hot Springs Spa

About an hour inland from Newport Beach, on the other side of the mountains in the Cleveland National Forest, is the much-talked-about Glen Ivy Hot Springs, founded in 1860. It’s the type of place where you can spend a full afternoon lounging and sipping cocktails by the pool with friends. Admission grants visitors daylong access to the spa's facilities, from the red-clay outdoor mud baths (cleverly deemed Club Mud) to the many mineral tubs (if you can stand the stinky sulfur, you’ll experience skin-softening bliss) to the bone-dry sauna. Spa treatments, such as facials and massages, cost extra and fill up quickly. The ancient Lomi Lomi Hawaiian massage is worth booking in advance and incorporates deep, gentle strokes. Go full circle with a meditation session and health food from the onsite Café Solé.
