Caldas de Bohi

Caldas de Boí is a celebrated high-mountain thermal spa in the Boí Valley of the Pyrenean county of Alta Ribagorça in Lleida, Catalonia, Spain — a valley of extraordinary natural and artistic significance that is home to nine Romanesque churches collectively designated a UNESCO World Heritage Site, representing the highest concentration of Romanesque architecture in the world. Its bicarbonate mineral springs, among the most abundant in the Spanish Pyrenees with numerous individual sources of varying temperature and composition, have been exploited therapeutically since at least the 16th century and developed into a formal spa hotel of international reputation in the 19th century. The surrounding landscape of the Aigüestortes i Estany de Sant Maurici National Park — Catalunya's only national park, with its extraordinary glacial lakes, granite peaks, and high alpine meadows — provides one of the most breathtakingly beautiful settings of any thermal spa in Spain. Caldas de Boí represents a pinnacle of the Pyrenean thermal experience: powerful mineral waters, UNESCO Romanesque heritage, and the magnificence of the Catalan Pyrenees combined in one of Europe's most remarkable mountain valley destinations.
