Schwesterinsel Nature Reserve is a protected island ecosystem in Lake Starnberg, Bavaria, known for its rich biodiversity, peaceful natural setting, and opportunities for birdwatching and quiet exploration.
The Schwesterinsel Nature Reserve is located on one of the small islands in Lake Starnberg (Starnberger See), southern Bavaria, Germany. As part of the region's network of protected natural areas, the island is preserved primarily for its ecological value, featuring a mix of mature deciduous forests, reed beds, and wetland habitats. The reserve provides important breeding and resting grounds for a variety of waterfowl, songbirds, and amphibians, as well as a habitat for rare plant species adapted to lakeside environments. The island itself is relatively small and is managed to maintain its natural character, with limited human disturbance, making it a favored spot for ornithologists and naturalists. Historically, the island was privately owned but was designated as a nature reserve to safeguard its fragile ecosystems from increased recreational pressure and development. Recreational access is generally limited to preserve the wildlife, although boaters and anglers often pass nearby, appreciating the scenic beauty of the reserve from the water. Close to the shores of the town of Bernried, Schwesterinsel forms part of the culturally rich and ecologically significant Starnberg Lake region, which combines outdoor recreation with rich Bavarian traditions. Visitors to the reserve area enjoy calm paddling, birdwatching, and the tranquility of the natural environment, especially during migration seasons when many bird species are present. The nearby hiking trails along the lake shore offer stunning views of the island and a chance to experience the natural diversity of this protected area.
