The Royal Corin Thermal Water Spa & Resort - Adults Only  

Perched in La Fortuna de San Carlos at the foot of Arenal Volcano, this adults-only thermal resort sits roughly 14 km from San Carlos city center and about 120 km from Juan Santamaría International Airport. The property is located a short drive from the town center — roughly 4.2 km from the local Catholic Church toward the volcano.

Forty-eight contemporary rooms spread across a modern five-story building, many with balconies and striking views of Arenal Volcano. Rooms come with air conditioning, minibars, flat-screen TVs, coffee-makers, bathrobes and slippers, and some feature jetted tubs or access to on-property thermal amenities. The vibe is modern-luxe and relaxed, perfect for couples seeking a thermal-spa escape.

Sink into private hot springs and thermal pools, or cruise the outdoor pool and spa facilities that include a sauna, steam room and treatment/massage rooms. There’s a fitness center, a library for quiet downtime, complimentary onsite parking, and easy access to excursions around Arenal. Wake up to volcano views and soak in mineral-rich waters.

Conference and meeting rooms plus a business center make small events and corporate gatherings possible. Free wireless internet is available throughout the property and a concierge can assist with transfers and event logistics.

On-site restaurant and café serve local Costa Rican flavors and regional specialties, while multiple bars — including a lobby bar, the Lava Bar and the Wet Bar — keep cocktails and casual bites flowing. Don’t skip the coffee; the cafe is a favorite for a morning pick-me-up.
