Băile Tușnad, in the Harghita county spa town of the same name set in a volcanic gorge carved by the Olt river through the Eastern Carpathians of Transylvania, draws on bicarbonate mineral springs in one of Romania's most scenically dramatic thermal settings — a narrow valley where the river has cut through ancient volcanic rock to create a natural amphitheatre of forested basalt cliffs surrounding the small spa resort. The naturally carbonated bicarbonate waters, rising from the volcanic geology of the Harghita mountain range — one of Europe's most recently active volcanic zones — are used in drinking and bathing within a long tradition of Romanian thermal culture. Băile Tușnad's position within the heart of Szeklerland — the historically Hungarian-speaking Székely region of central Transylvania — gives the spa a distinctive cultural duality, celebrated in both Romanian and Hungarian wellness tourism for its remarkable natural thermal resources.
Insider tip — Nestled in a gorge of the Olt River at the southern tip of the volcanic Harghita mountains, Bai Tusnad is Romania's smallest town and one of its most scenically dramatic spa resorts. The bicarbonate-rich mineral springs emerge from old volcanic conduits and are traditionally used for cardiovascular and digestive treatments. The surrounding forested slopes offer trails to crater lakes including the famous Sfanta Ana. Take the cable car for panoramic views before descending to the baths.
