The route that we follow has two phases, in the first one we ascend in a very direct way, gaining a lot of altitude to leave the bottom of the valley. Then a diagonal is made to later alternate slopes and plateaus until you reach Mittelberglesee.

00:00 Start. We take the track that begins next to the car park and crosses the river. Just after crossing it, we take a path to the right (direction W) instead of following the track that goes to the south. The path ascends through a forest in a very direct way, with a high slope. As we go forward, the forest loses density until it becomes a scrubland.

00:40 End of the forest. The forest ends and the path makes a diagonal, also very direct, to the right (NW) by scrubland.

00:55 Change of direction. We reach a plateau, where the path makes a notable change of direction towards the southeast (left). The path softens and gradually gains altitude, making a diagonal that cuts the slope.

01:30 Couloir. We arrive to a wide couloir where a river flows, the path ascends more sharply towards the bottom of the channel.

01:50 Plateau. We climb a first slope that takes us to another plateau, where the river runs quieter and meandering. We ascend parallel to the river on its left side, to climb the last pass that takes us to our destination.

02:15 Mittelberglesee. We reach the lake, from where we can enjoy stunning views. The descent path is the same, at 03:05 we arrive at the change of direction, at 03:25 we entered the forest and arrive at Trenkwald at 03:45.
