looking for something specific?
If you are looking for a relaxing way to see the sights along the Neckar, then taking a boat trip might be just the thing. Several types of cruises are available from round-trip to point-to-point, regular boat to solar-powered, making it possible to spend just a little time or the entire afternoon along the river.
The HeidelbergCard also offers a discount on some of the cruises.
