Naj Naay Spa at The Beach Tulum

Naj Naay offers a hydrotherapy circuit with sauna, Turkish steam bath, hot and cold pools and a Scottish shower. Its current operator page says the circuit is available as a standalone experience without a reservation, and it is also included with independently booked spa treatments. Hotel guests get complimentary access; visitor terms should be confirmed with the spa before arrival. The photo shows the actual sauna and steam entrances.

Hydrotherapy daily 10:00–18:00; treatments 10:00–20:00
