Isar headwaters

Highlight • River

You should only go to the source of the Isar River or the Kastenalm by bike. Walking on the sunny forest road is a miserable slog, especially in summer.

The cycle path along the upper Isar from Scharnitz to the source of the Isar is easy to ride on and leads through an extremely attractive landscape through which the turquoise and sometimes wild Isar flows.

A footpath led to the alpine pasture. It was well worth the effort! Fresh water, a toilet, and the icing on the cake: a sandwich!
I headed for the spring on the way back. I couldn't find Roman I.

The path along the young Isar River was busy. Not exciting, not difficult, but still: Alpine feeling.
