Rottachsee - Petersthal (Allgäu)

Rottachsee – Petersthal is a wind-based lake spot on the southeastern shore of Rottachsee, centered around a shallow pebble launch and a large grassy rigging area. The water is generally described as clean and flat to choppy, with no notable currents and an easy-to-moderate setup for getting on the water. For wind sports, SW to WSW/W winds are the main driver. Conditions are typically best from late spring into early autumn, and the wind is often gustier near the shore where trees and local terrain can create uneven loading. Windsurfing is described as the most straightforward and popular option here, with convenient rigging and shallow entry. Kitesurfing is allowed but requires extra caution: the launch area is comparatively small and wind gusts can be strong near the trees. Riders are expected to use the designated zones and keep clear of marked swimming areas and environmental protection zones. Pebble entry also means you should manage your step-in and board handling carefully. For wingfoiling, the grassy launch area is well-suited for setup, and the reservoir depth increases quickly after a short walk-out, making it a good place to learn and progress on foils within the sheltered/managed lake conditions. In cooler shoulder seasons, water temperatures drop notably, so wetsuit thickness becomes an important part of comfort and safety.
