Nice destination with good restaurant: Lauerzersee & Insel Schwanau (CH)

It's a great place for a Sunday afternoon excursion or for a nice meal.

This little island "Insel Schwanau" is situated in the Lauerzersee and offers a small castle ruin and a guild restaurant. You can also have a coffee in the afternoon with great views onto the lake and the surrounding mountains (e.g. Rigi, Mythen, etc.)

One of the highlights is the restaurant owned boat transfer.
Note: it is free when you have a restaurant reservation; otherwise you pay a small fee.
