10 Best Spa Hotels in Belgium (2026)

Framed by rolling green countryside, historic towns and the famous thermal springs of Spa, Belgium is a compact but well-set-up destination for proper rest and recovery. Here you’ll find everything from full-scale spa resorts with indoor and outdoor pools to smaller hotels offering good value wellness facilities in city settings. Whether you’re looking for the best spa hotels for a weekend reset, the most affordable places to unwind, or somewhere a little more polished for a longer stay, Belgium has a solid mix of spa hotel options that make switching off easy.

For an active break

• Villa de Noailles is full of charm, with four-poster beds and freestanding bath tubs made for relaxing. Start the day with a big breakfast, then head out cycling, skiing, hiking, or even horse riding and fishing. Thermes de Spa is just minutes away and offers massages, facials, hydrotherapy, and thermal baths.
• Right on Lake Robertville, not far from Waimes, Hotel des Bains is perfect for unwinding, with big windows and warm parquet floors in the rooms. The spa features a Nordic sauna, Moorish steam room, hot tub, and a range of body and facial treatments. Outside, hike Belgium’s highest peak, rent a bike, or boat on the lake, then end the day with dinner by the lake.
• Just outside Liège, Domaine des Thermes mixes historic charm with modern comfort. Spend your day exploring castles, hiking trails, or wandering medieval streets. The spa’s heated pool, saunas, hammam, hot tubs, and tailored wellness treatments are a treat, while the restaurant serves fresh Belgian dishes. 
• Opposite Knokke’s casino, Hotel La Reserve has spacious rooms, sunny terraces, and a private wine cellar. The spa pampers guests with hammam sessions, massages, and a pool, while active travellers can cycle the dunes, tee off at Royal Zoute golf course, stroll along the beach, or explore the Zwin Nature Park.

For a city break

• Right on Brussels' Rue Royale, Corinthia Grand Hotel Astoria is a stalwart of the capital's five star accommodation scene and boasts gilded ceilings, Art Deco lights, and stained glass windows. The spa’s marble pools, steam rituals, and expert treatments are perfect for unwinding, while Michelin-starred dining, a buzzing cocktail bar, and the theatre scene nearby deliver a vibrant city stay.
• Botanic Sanctuary is set in a stunning 15th-century monastery in Antwerp. Two Michelin-starred restaurants, boutique shopping, and cycling around City Park keep things lively. The Botanic Health Spa is utterly spoiling with saunas, hammams, and private whirlpools. 

For foodies

• Tucked on the edge of the Ardennes forest just outside Spa, Manoir de Lebioles is a dream for both food lovers and those in need of some relaxation. Rooms have cosy fireplaces and four-poster beds, but the real highlight is the Michelin-listed restaurant, serving inventive, seasonal dishes with a wine list that’s just as impressive. The indulgent spa offers hot stone massages, aromatherapy baths, and steam room sessions.
• Right in the heart of Durbuy, with views of the medieval castle, Le Sanglier des Ardennes is a treat for foodies. Two restaurants serve everything from refined fine dining to creative tapas, while the spa pampers guests with hammam sessions, saunas, and a range of rejuvenating massages — perfect after a day kayaking or exploring.

For a country escape

• Hidden in the Belgian countryside, Naxhelet Golf Club is a converted farm just outside Wanze that feels like a proper getaway. Bedrooms have parquet floors and natural stone, while the spa spoils you with saunas, a hammam, an ice pool, and indulgent treatments. Afterwards, grab a table at La Cuisine for creative dishes made with fresh, local ingredients.
• Chateau de Vignee oozes character in the Ardennes countryside near Rochefort, with velvet armchairs and moody interiors. The spa invites you to relax with massages, a sauna, and hammam sessions, while the restaurant serves impressive dishes from Chef Marius Bosmans, as well as treasures from the 13,000-bottle wine cellar.
