This Hotel in Mexico Has a Subterranean Saline Cave Pool & Spa 🌊 ✨ 🇲🇽

If your idea of a perfect Mexico getaway involves exploring ancient Mayan ruins by day and soaking in a saltwater cave 6 meters underground by night... we found your hotel. Zentik Project is a boutique hotel in Valladolid, Yucatán, with an impressive underground cave transformed into a saltwater pool heated to a toasty 95–100°F. The warm saltwater is designed to help you unwind, ease stress and fatigue, and has anti-inflammatory properties. This stay in Valladolid is also just a short drive from Chichen Itza, and we found stays from $99 a night with breakfast included.

It’s also got a 4.6/5 rating on TripAdvisor and was named a 2026 Travelers’ Choice Award winner, so apparently we’re not the only ones who think this place is pretty special.
