A beautiful road through Valle Daone leads to Lake Boazza. Along the way to Lake Boazza you already will see several unknown/unnamed waterfalls coming down from the mountains. But Cascata della Val Boazzo is of exigent beauty.
The best view you will have is from the restaurant just outside the tunnel (gps 46.005384, 10.517529), also a perfect place for a lunch. It is also possible to drive/walk to the bottom of Cascata della Val Boazzo, but the view won’t get better.
If you drive a little bit further into the valley, another big waterfall shows up at the right side of the road, not perfectly visible, but from the lake you will have a better view.
