Small chapel at the head of the valley right next to the large water playground, a paradise for children. Highly frequented by the Talschlusshütte and large suspension bridge with treetop path. Still highly recommended with children.
If you don't want to walk far, you can take a nice walk at the head of the valley. I found it to be crowded and touristy. A contrast program when you come down the steep paths from the Seven Summits Tour.
