Starre Vartan, Author of The Eco-Chick Guide to Life: I was born and spent many summers in Australia, so I'm a water baby. I love any beauty treatment that includes baths, especially those that involve moving between hot and cold waters and skin scrubbings, like
the ritual hammam in Northern Africa, or traditional Scandinavian sauna. I make bathing one of my top priorities whenever I travel, and have enjoyed a dip in Bath, England, Wiesbaden, Germany, and Harbin
Hot Springs in California. My top so far were the natural steam caves on the Big Island of Hawaii, which are unmarked and require a bit of bushwhacking to find, but are literally the exhalations of Mother Earth (and the best steaming I've ever experienced) and the Arenal volcanic hot springs of Costa Rica.
