Gran Hotel Balneario De Puente Viesgo  

Tucked in Puente Viesgo, Cantabria, this thermal hotel sits beside the Pas River and the Monte Castillo caves (a short walk). It’s an easy drive to Cabárceno Natural Park, Santillana del Mar and the city of Santander. About 28 km from Santander airport and 90 km from Bilbao, the spot is family-friendly and ideal for nature and culture day trips.

A thermal complex with over 130 guestrooms, the hotel blends wellness facilities with simple, comfortable rooms. Expect in-room minibars, bathrobes and private baths. The setting feels riverside and restorative, with a Neo‑Romanesque church and UNESCO-listed caves steps away.

Soak in thermal pools and spa treatments, or pulse through a workout in the gym. There are indoor and outdoor pools, a sauna, steam bath, solarium and massage therapies. Families can use playrooms for kids, and the tour desk/concierge will book local excursions. Wake up to riverside mornings and unwind with wellness services and an on-site doctor.

Event-ready with a business center and wide saloons for meetings and private functions. Complimentary wireless internet and on-site parking keep things practical for work stays.

Dine at El Jardín, grab coffee and snacks in the café, or order 24-hour room service. Continental breakfast is served each morning (hours typically early). Finish the day with a drink at the bar/lounge.
