Built at the foot of Mount Pinatubo the Puning Hot Springs and Sand Spa in Clark, Pampanga is a different take on the spa experience. First you'll have to rough it up and take a 4x4 through a stream. Then you get to the hot springs, where the thermal waters of Mount Pinatubo soothe your muscles. And for a unique spa session, lay back and let warm volcanic sand envelop your body for total rejuvenation. Definitely an out of the ordinary treat for spaholics!
