Overview

2 hours 30 minutes

Mobile ticket

Step into a rare urban sanctuary in the heart of Old San Juan. Las Ruinas is a full-circuit thermal spa, bathhouse, and wellness gym — a 2.5-hour escape purpose-built to quiet your mind and body.

Move through four wellness environments at your own pace during your 2.5-hour session: the heated swimming pool and contrast plunge pools, three distinct heat sanctuaries (dry sauna, infrared sauna, and eucalyptus steam room), a restorative lounge with unlimited herbal tea and light snacks, and a fully equipped gym. Every visit includes a dedicated locker and unlimited fresh towels — just bring a swimsuit and flip-flops.

Between circuits, sink into the cozy lounge wrapped in soft towels. This is wellness done simply and completely. Before you leave, refuel at the in-house Smoothie Spa with nourishing blends made to refresh

Sessions are capped at 20 guests for an unhurried, intimate atmosphere. Located steps from Old San Juan's historic streets — the perfect pause in the middle of any itinerary
