About Termas de Caldelas
Termas de Caldelas, Portugal is a historic Minho thermal spa in the Caldelas village of Amares municipality, between the city of Braga and the Peneda-Geres National Park in northern Portugal. The mineral water emerges from the ground at approximately 32 degrees Celsius with a mild alkaline pH of 8.1 to 8.3, a hypomineralised classification, and a bicarbonate calcium-sodium ionic composition that also carries fluoride. Archaeological remains show the hot springs were already in use in Roman times, making this one of the longer continuously documented thermal sites in the Minho. Braga, one of the oldest Christian cities in the Iberian peninsula, is the nearest major city.
These termas sit in a green, enclosed park at the gateway to the Peneda-Geres National Park, the only national park in Portugal. The spa complex includes the historic bath house and water spouts, a dynamic pool, a physical medicine and rehabilitation centre, and the Grande Hotel da Bela Vista. The complex has been renovated in a sober traditional style and operates seasonally, typically from April or May through October or November. Treatments focus on digestive, skin, and rheumatic conditions.
Termas de Caldelas is one of the most historic hot spring resorts Portugal preserves in the northern Minho region.

Minho and Peneda-Geres Region
Caldelas sits in the Minho province, Portugal green and historic north-western region, known for Vinho Verde young wines, dense granite villages, and the Peneda-Geres National Park. Peneda-Geres is Portugal only national park and preserves granite peaks, oak and pine forests, Roman roads, and wild Garrano horses. The combination of medicinal thermal bathing, Minho cuisine (francesinha, bacalhau, Vinho Verde), and national park day trips makes a strong multi-day northern Portugal itinerary.
Suitability & Accessibility
Who Should Visit Termas de Caldelas

Wellness packages range from single-day experiences (Aquae, Equilibrium) through two day Thermalrelax and Dermotermal courses to three-day Anti-stress programmes, with structured 7-day and 14-day weight-loss programmes also offered. These aguas termais are open seasonally, typically April or May through October or November, with weekday hours from 08:00 with afternoon sessions by season. This hot spring resort Portugal travellers often pair with Peneda-Geres hiking.

Safety & Etiquette
Termas de Caldelas Safety Tips
Termas de Caldelas is generally safe for guests as a fully staffed and medically supervised thermal spa with on-site hydrology medical consultations available, but visitors should still follow the resort schedule, hydrate regularly, and respect the structured morning and afternoon treatment sessions.

Towels and robes are included in classical thermalism packages. Respect quiet areas for medical consultations and treatments.
