Octant Hotels Furnas

Inside a Living Crater

Furnas is unlike almost anywhere else in Europe. Steam rises from the ground. Iron-rich water bubbles beneath the surface. Gardens grow with almost tropical intensity. The air carries the unmistakable mineral scent of geothermal activity. Octant Hotels Furnas sits directly inside this landscape. The hotel occupies the former Furnas Thermal Center, reworked into a contemporary retreat where the island’s volcanic energy becomes the defining experience. You are not merely staying near the hot springs. You are sleeping inside the ecosystem that created them.

A Contemporary Reading of the Azores

The architecture is calm and low-key. Large windows, timber, stone, dark surfaces, and abundant greenery create interiors that feel contemporary without becoming disconnected from place. Madeiran designer Nini Andrade Silva gives the rooms their character through a palette drawn from the landscape: volcanic greys, dense greens, sulphuric yellows, and enlarged photographic images of waterfalls, rock formations, and island vegetation. Vintage details sit alongside contemporary furniture. Marshall speakers, timber finishes, tactile fabrics, and restrained lighting give the guestrooms warmth without visual noise. The mood is restorative. Exactly what Furnas requires.

Thermal Water, Day and Night

Water is the hotel’s real architecture. Two naturally heated thermal pools — one indoors, one outside — remain open 24 hours a day. The indoor pool sits beneath a dark, barn-like structure with a dramatic glazed roof, while the outdoor pool is wrapped in dense greenery and timber decking. Both are fed by the geothermal system beneath Furnas. The water can reach around 40 degrees Celsius. Soaking here after dark, with steam rising into the cool Azorean air, is difficult to forget.

A Spa Built on Geology

The thermal circuit extends far beyond the pools. Sauna, laconium, Turkish bath, hydrotherapy, aromatic showers, treatment rooms, and flotation beds create a substantial wellness program. Many treatments draw on ingredients that feel almost edible: olive oil, rosemary, seaweed, salt, coffee, cocoa, pineapple, and green tea. That playfulness suits the setting. This is not a sterile medical spa. It is wellness interpreted through São Miguel’s landscape and agricultural culture.

À Terra

The restaurant is aptly named. À Terra cooks with fire, earth, smoke, and local produce. A wood-fired oven, Josper grill, and hearty regional cooking give the menu a deeply grounded quality. Fresh fish, beef, vegetables, breads, stews, and local cheeses dominate, with ingredients sourced heavily from the island. The most memorable experience is the cozido. Ingredients are prepared in the morning and lowered into geothermal ground near Furnas, where volcanic heat slowly cooks the stew before it returns to the table that evening. Few meals connect more directly to geology.

A Greenhouse for Drinks

The lounge and bar continue the indoor-outdoor atmosphere. Glass roofing, hanging plants, warm timber, leather seating, and open edges create something closer to a greenhouse than a conventional hotel bar. Pineapple naturally appears everywhere. São Miguel is famous for greenhouse-grown pineapple, and the hotel uses it in cocktails, juices, desserts, and liqueurs. The island’s own tea from Gorreana, regional cheeses, breads, dairy, and fruit also make breakfast one of the strongest expressions of place.

Furnas Beyond the Hotel

The surrounding landscape makes sitting still surprisingly difficult. Terra Nostra Garden, Furnas Lake, fumaroles, waterfalls, crater viewpoints, and hiking trails are all close by. Guests can borrow bikes or kayaks, explore the island by car, or follow forest paths directly into the surrounding greenery. Then return to the thermal pools. Repeat as necessary.

Why It Works

Octant Furnas succeeds because geothermal wellness is not a concept imposed onto the hotel — it is the landscape beneath it. The former thermal centre gives the property historical continuity, Nini Andrade Silva’s interiors translate the Azores into colour and texture, and the pools, spa, cozido, local food, and volcanic setting all reinforce the same story. Furnas is already one of Europe’s most extraordinary natural environments. Octant simply gives you a beautifully designed way to live inside it.
