Qua Baths & Spa sits on level two of the Octavia Tower at Caesars Palace and is built around a set of Roman baths kept at different temperatures. The heat circuit adds a cedarwood sauna, a herbal steam room and the ultra-heated Laconium, and guests cool off in the Arctic Ice Room, where snow falls from above, before resting in the tea lounge. The spa opens daily from 9 am to 6 pm; a pass costs from $65 for hotel guests and $110 for visitors.
