These women are indulging in a Blue Lagoon specialty: Silica Mud Masks. Included in the admission price is the chance to wade across the pool to the Silica Bar. Then dip your hands into a pot of warm, wet clay and smear it on your face and body. Go ahead! Don’t be nervous or self-conscious. The experience is unique, fun and heavenly. When you wash off a few minutes later, your skin will have a luxurious softness and glow.
