Ore-rich salt crystals mined from the Himalayas. Mud dug from the mountains of Korea's Chungcheong Jincheon region. Such substances, prized for their energizing and detoxifying powers, line the floors and walls of Crystal Spa's four mineral-therapy rooms constructed in the style of a traditional Korean jimjilbang. Beyond these natural therapies, the facility also maintains a designation as an Aveda Concept spa. This means that its practitioners use Aveda's plant-derived products during each massage, body treatment, and facial they perform. Further amenities include soft water fresh from the spa's filtration system, complimentary WiFi, multiple big-screen TVs, and a cinema-size viewing screen that plays sporting events, movies, and 42-hour vacation slideshows. The staff also serves select dishes from Korean restaurant Sohyang in a café replete with traditional low tables and floor-level seating.
