ARIA Spa & Salon

ARIA Spa & Salon sits inside the ARIA Resort & Casino on the Las Vegas Strip and is built for hotel guests rather than walk-in day-trippers. Access is restricted to those staying at the resort, and the facility is adults only, with a minimum age of 18. The spa has earned the Forbes Travel Guide Five-Star award and is described as the largest Forbes Five-Star spa in the world.

The wet area covers the basics well: sauna, steam room, a thermal pool setup, and a cold plunge for contrast therapy. The facility is clothing optional, and there's no dress code required for treatments. Beyond the thermal circuit, the property includes private spa suites and a relaxation lounge for guests looking for a quieter, more secluded experience between treatments.

Booking a treatment requires an appointment, a credit card on file, and ID at check-in. A 20% service charge is automatically added to spa and salon services, with tipping beyond that left to discretion. Note that booking a salon-only service, like a haircut or pedicure, does not include access to the spa facilities themselves, so guests wanting the sauna, steam and pools need to book an actual spa treatment or facility pass.

Hours run daily from 8:00 AM, closing at 6:00 PM on Fridays and Saturdays and 5:00 PM the rest of the week. Treatments are bookable from 9:00 AM to 6:00 PM. Parking is available on-site for those staying at or visiting ARIA.
