Quick answer: for a historic thermal spa, Vidago Palace in the north. For a spa in the vineyards, Six Senses Douro Valley. Near Lisbon, Penha Longa. In the Algarve, Conrad Algarve or Vila Vita Parc. On the islands, Octant Furnas (Azores) for 24-hour thermal pools or Savoy Palace (Madeira). For a budget-friendly thermal escape, Pedras Salgadas.

Why Portugal is great for a spa break

Portugal has a long tradition of termas, thermal baths built around mineral springs. Some date back to Roman times, and many grew into grand spa towns in the late 19th and early 20th centuries. Today you can choose between these historic springs, modern resort spas with big indoor pools, and the volcanic hot water of the Azores. Prices are often lower than in other parts of Western Europe, and the mild winters make a spa break worth booking all year.

Thermal spa or hotel spa?

A thermal spa uses natural spring water, often rich in minerals, in its pools and treatments. At traditional Portuguese termas, a course of classic water treatments usually starts with a short medical check. A hotel spa is simpler: you book a massage or a session in the pool, sauna and steam room. Several hotels below offer both.

The north

Vidago Palace

A grand Belle Époque palace hotel in a park in Trás-os-Montes, with a thermal spa designed by architect Álvaro Siza Vieira and a golf course. The palace opened in 1910 and was restored to its old glamour. It has about 70 rooms, and the spa has indoor and outdoor pools. Pure elegance. Check prices

Pedras Salgadas Spa & Nature Park

Eco-houses and treehouses in a historic spa park, with a thermal spa (a small extra fee). The spa is a restored historic bathhouse, reworked by Siza Vieira, with a heated indoor pool, sauna and hammam. Great for families and nature lovers. It is a short drive from Vidago, so you can combine the two, and the old spa town of Chaves is nearby. Check prices

Choosing the right spa hotel

• For real thermal water: Vidago Palace, Pedras Salgadas, Villa Termal Monchique or Octant Furnas.
• For a spa with wine: Six Senses Douro Valley or L’AND Vineyards.
• For a city break: Corinthia Lisbon.
• For beach and spa: Conrad Algarve or Vila Vita Parc.
• For families: Penha Longa and Pedras Salgadas have the most space for children.

When to go

Autumn and winter are the best value, with quieter resorts and lower rates outside the Christmas and New Year weeks. The Algarve and Madeira stay mild in winter. The north is cold and often wet from November to March, which makes a thermal spa especially cosy. In summer, book treatments early, as resorts fill with families.

Tips

• Book treatments ahead, especially at weekends.
• Check what is included: some hotels include the spa pool and sauna, while others charge extra for the thermal circuit.
• Age limits: many spas don’t allow young children in the spa area, or only at set times.
• Thermal water can be rich in iron and minerals, so bring an old swimsuit for the Azores.
• Winter is the perfect time for a spa break: lower prices and cosy days.
• You will want a car for the rural spas in the north and the Alentejo.
