Rottachsee is a reservoir in Petersthal in the Allgäu. It is about 4.8 kilometres long and around 12.8 kilometres in circumference. Swimming, sailing, surfing, diving and fishing are among the recreational activities available at the lake. Facilities also include changing rooms, kiosks, play areas, a beach volleyball court and boat moorings. Individual facilities may change over time.

Water Activities and Circular Trail

A cycling and walking trail just under 15 kilometres long circles Rottachsee and offers views across the Allgäu Pre-Alps. When planning, it helps to distinguish between the lake’s circumference and the trail’s length: the lake is around 12.8 kilometres in circumference, while the cycling and walking route is just under 15 kilometres long. The trail length is therefore the relevant figure for the circuit. Routes and conditions may change; check the current situation before setting out.

Getting to Petersthal

Travellers by regional train can arrive via Oberzollhaus or Oy stations; both are approximately five kilometres away. Check current train connections before travelling. By car, take the Oy-Mittelberg exit on the A7, continue on the B309 towards Nesselwang, then turn towards Oy and Petersthal. The approximate distance from the station is a separate point to consider for the final leg; by car, follow the sequence of exit, main road and turn-off.
