Discover some of the world's most remarkable geothermal spa hotels, from Iceland's Blue Lagoon and Japan's Amanemu to historic retreats in Italy and Spain. Read on for our guide to exceptional spa destinations, showcasing natural hot springs and luxury hospitality in unique surroundings.
The world’s most luxurious geothermal spa hotels
For centuries, natural hot springs have drawn visitors seeking spectacular surroundings and time-honoured bathing traditions. Today, many of these remarkable locations are home to geothermal spa hotels, where volcanic landscapes, historic estates and contemporary retreats offer an altogether different kind of escape.
Some of these geothermal pools are world-famous destinations in their own right, while others are reserved exclusively for hotel guests. We've selected some of the most luxurious examples around the world, each offering its own take on the hot spring experience. If you're planning a visit, our private charter service can help simplify the journey.
The Retreat at Blue Lagoon, Iceland
The famous Blue Lagoon hot spring has become synonymous with Iceland's dramatic volcanic landscape. Its mineral-rich azure water, drawn from 2,000 metres below ground, maintains temperatures of 37–40°C throughout the year, while lava fields and drifting steam create an atmospheric setting.
While many visitors come for a few hours, you can stay longer at one of the world’s top luxury hot spring resorts. Built into an 800-year-old lava field beside the lagoon, The Retreat reflects its surroundings with understated interiors and views across moss-covered rock formations. Guests can sample Icelandic tasting menus at Moss Restaurant before exploring the Reykjanes Peninsula or continuing to Reykjavik.
Keflavík International Airport (KEF) lies an easy 20-minute drive away from the Blue Lagoon and is home to a private terminal welcoming charter flights.
The Springs Resort & Spa at Arenal, Costa Rica
Overlooking the Arenal Valley beneath Costa Rica's famous volcano, The Springs Resort & Spa occupies a 165-acre estate surrounded by rainforest and offers spectacular vistas from every room. Its 28 naturally heated pools are dotted through the grounds, ranging from large open-air terraces to quieter lagoons secluded in the jungle with uninterrupted views of the lush landscape.
Beyond the thermal springs, the property is known for its wildlife rescue centre, pampering spa and thrilling outdoor experiences such as river tubing, kayaking and rock climbing.
The nearby town of La Fortuna acts as a gateway to Arenal Volcano National Park, while Juan Santamaría International Airport (SJO) in San José offers convenient access to the region.
Amanemu, Japan
Nestled in Ise-Shima National Park overlooking Ago Bay, Amanemu draws inspiration from the traditional Japanese ryokan while embracing contemporary design. One of the world's most luxurious spa retreats with hot springs, the property centres around Japan’s ancient onsen culture, with forested hills and views across the Pacific adding to the sense of seclusion.
Amanemu's 2,000-square-metre spa is designed around a natural hot spring, while each of the 30 suites and villas has its own deep soaking tub fed by onsen water. The hotel is a great base for exploring the coastline, visiting nearby shrines and fishing villages or enjoying the tranquillity of the surrounding national park.
Chubu Centrair International Airport (NGO) supports private jet charter arrivals, with onward limousine or helicopter transfers available to Ise-Shima.
Bagni di Pisa, Italy
Once the summer residence of the Grand Duke of Tuscany, Bagni di Pisa is an 18th-century palace located on the slopes of Mount San Giuliano between Pisa and Lucca. One of Italy's most popular thermal spa getaways, it combines centuries of history with views across the Tuscan countryside, while the iconic Leaning Tower of Pisa is just a short drive away.
Much of the building's original character remains, with frescoed ceilings, period artwork and grand reception rooms reflecting its aristocratic past. The spa occupies two historic bathhouses fed by natural thermal waters and includes a steam grotto carved into the hillside.
Located a 25-minute drive from Bagni di Pisa, Pisa International Airport (PSA) is a convenient entry point to the region within easy reach of Florence and the Tuscan coast.
Castilla Termal Monasterio de Valbuena, Spain
Surrounded by vineyards in Spain’s acclaimed Ribera del Duero wine region, Castilla Termal Monasterio de Valbuena occupies a beautifully preserved Cistercian monastery. Perfect for travellers looking for storied wellness hotels, the property blends Romanesque architecture with centuries of monastic history, while water drawn from 386 metres below ground plays a central role in the experience.
The restored monastery features elegant guestrooms, a thermal pool and a restaurant showcasing local produce, while the surrounding wine region offers opportunities for tastings and visits to nearby estates. Valladolid Airport (VLL) provides easy access to the area, while Madrid-Barajas Airport (MAD) offers additional connections if you’re continuing through northern Spain.
