This is a perfect Sunday plan. In the morning hiking still in the shade, good lunch (i know just the place) and lazy afternoon sunbathing on the river shore.
The park trail is one big loop with lot of branches so that means you can walk as much as you want and always find an easy turn to come back to your starting point.
There are not only few interesting points on the way, bridges, mills, old concrete factory, church and castle, but all this area represents important geological site.
I enjoyed the old concrete factory
After all this walking in a hot day just in our starting point in Mulino del Ghitello there is a beautiful restaurant Ristorante al Ghitello with local wine list and products of Ticino.
