Sailing and windsurfing are the most popular sports here. Both can be arranged (June-Sept) at Segel Surfschule (tel. 08022/75472; www.segelschule-stickl.de) near the town of Gmund, 9.5km (6 miles) north of Rottach-Egern. Windsurfers cost from 45€ for a 3-hour rental.
You can take a 1-hour cruise around the lake on one of the ferryboats operated by Bayerische Seenschifffahrt (tel. 08022/9-33-11). Boats operate about every 90 minutes from 8am to 8pm, and a circular tour from Tegernsee costs 16€.
In summer, you can walk and hike along the lakeshore. In winter, because of its small size, the lake freezes over, making it an attraction for skaters.
