For a fairly long stretch, you can travel back and forth in the valley on the still-existing tracks on the Dreysene. The acacia shoots make the ride interesting for those sitting on the tree side, and there are plenty of views of the valley.

A rest area at the train station. There's more than just tables and benches here, plus a nice place to linger.
