Best Spa Sanctuaries in the US Tucked into the north corner of Napa County, Calistoga used to be the last stop on the train from San Francisco--and it never lost its historic, somewhat quirky charm. Family-owned Indian Springs Resort & Spa has been around in one form or another since Calistoga forefather Sam Brannan created it as a turn-of-the-century health spa. When your schedule is the only thing more crunched than your neck muscles, a short-haul spa getaway is the key to relief. And happily, there are spas all over the United States that are every bit as unique, exclusive and "away from it all" as any far-off island retreat. Check out our list of top spa sanctuaries in your big backyard. Courtesy Indian Springs Resort, text by Lena Katz, JustLuxe.com
