About Bedřichovská přehrada, Černá Nisa
The Bedřichov reservoir, built between 1902 and 1906 on the Černá Nisa stream, sits at about 775 m in the Jizera Mountains roughly 3 km north of Bedřichov and 13 km from Liberec. It is described as the highest-lying dam in Bohemia. The water is clear and reaches about 15 m deep, and the shores are wooded, with grassy and rocky patches rather than a built beach. In summer the lake works as a natural swimming spot, and the Jablonec tourist information service states that swimming is possible with or without a swimsuit; a geocaching guide to the dam also notes that naturists seek the water out. There is no marked nude section: people who swim nude tend to spread out along the quieter banks away from the dam crest and the paths, especially towards the inflow end. The reservoir is inside the Jizera Mountains protected landscape area, closed to cars, so it stays fairly calm compared with lowland bathing lakes. Since 2013 a barrier-free path with two viewpoints and information boards has run along the shore. Expect cold water even in July, given the altitude.
Getting there
The reservoir can only be reached on foot, by bike, or on cross-country skis in winter; there is no road access for cars. Most visitors start from Bedřichov or Rudolfov and walk or cycle about 3 km on forest roads to the dam. Parking is in Bedřichov (the ski-resort car parks) rather than at the lake; check local charges. Bedřichov has bus links from Jablonec nad Nisou and Liberec. A barrier-free walking path follows part of the shore, but the quieter swimming spots are reached on informal forest paths.
Amenities
Legal context
There is no designated nude area. The Jablonec tourist information page (accessed 2026) states that swimming at the reservoir is possible with or without a swimsuit, which reflects a long-tolerated custom rather than a formal designation. The lake is in the CHKO Jizerské hory protected landscape area, so protected-area rules (no cars, no camping or fires) apply.
Naturism at Bedřichovská přehrada, Černá Nisa sits under Czechia's rules for traditional tolerance — custom more than statute.
