There is often traffic in the village of Pr - take a little bit care. (but the traffic leaves the bikeway after some hundred meters to the right)
This section of Valle-di-Ledro-Bikeway continues directly from the dirt road of the lower bikeway.
Cross the bridge, enter the village of Pr and follow the bikeway signs uphill to the left. In the center of the village, you'll find drinking water.
Leave the group of houses on a tarred road upward. First, the road will follow the creek on your left hand. The road grade in this section varies and is sometimes a little bit steep. The creek becomes smaller and when you change to the other bank, there will be a dirt road for some hundred meters.
You'll reach the small town Molina di Ledro, and will ride into town near the stadium. Follow the signs through the small town, and continue upward to Lago di Ledro.
It is rideable in both directions, but is recommended mostly for uphill travel. (There are a lot of better trails for downhill in this area.)
