In the Danube River, between Buda and Pest, verdant Margaret Island is a tranquil getaway within the city. Pedestrian promenades navigate around parkland, an art nouveau water tower, the ruins of a 13th-century Dominican convent, a musical fountain and a small zoo. Other attractions include jogging tracks, thermal spas and swimming pools. Summertime brings pop-up bars and restaurants, as well as live music.
