Healing hot mineral waters are discovered in 1913 at the foot of the San Bernardino Mountains. Almost 100 years later, “California’s Spa City” attracts visitors globally. Water naturally heated underground to as much as 180 degrees has resulted in more than two dozen spas and spa hotels, including the celebrity-studded Two Bunch Palms Resort & Spa, soothing Miracle Springs Resort, and DogSpa and Wellness Center for traveling with your pup.
