Visit Heidelberg in summer and enjoy sunbathing on the Neckarwiese or explore the romantic old town in mild evening temperatures. In the warm season, life in Heidelberg's winding streets blooms: The many cozy cafés and pubs offer places in the summer air and in the middle of the hustle and bustle of our city. A multitude of cultural highlights will make your summer in Heidelberg an unforgettable experience. And because the sun shines so much nicer here, the third night is at our expense with this arrangement.
