TripSavvy feature: The Best Thermal Baths in Budapest

Known as the ‘City of Baths’, Budapest sits on a fault line and its thermal baths are naturally fed by 120 hot springs. The city is home to an impressive selection of thermal baths, many of which date to the 16th century. We’ve rounded up the best of the bunch including a sprawling neo-baroque palace, a rooftop pool overlooking the Danube and an ancient Ottoman bathing house that’s open until 4 a.m. every Friday and Saturday.
