Hindens rev, Nature reserve at Lake Vänern, Sweden

Hindens rev is a peninsula that extends into Lake Vänern, stretching roughly five kilometers with a varying width between 25 and 100 meters. The landform rises about 21 meters above the water surface.

The peninsula formed roughly 11,000 years ago as a terminal moraine during the Younger Dryas period, when glacial materials were deposited at the ice margin. This geological feature developed from the retreat of ancient ice sheets across the region.

The name rev refers to the underwater reef the ridge becomes beyond its tip. In summer the reserve is used for hiking, fishing and birdwatching; in winter long-distance skaters cross the ice along the moraine. The reserve, 13 hectares, has been protected since 1986.

The reserve covers 13 hectares and has been protected since 1986. The peninsula is highest at the mainland end and slopes gradually for five kilometres to its tip, so the walk out is easy but the return is gently uphill. In winter the frozen lake is used for long-distance skating.

When water levels rise, five elongated islands called Killingarna emerge around the submerged middle section of the peninsula. These temporary islands disappear again as water levels drop.
