Olšina is one of the oldest and most atmospheric ponds in the Bohemian Forest — a vast, mirror-like stretch of water nestled among spruce forests at 731 metres above sea level, with a history stretching back over six centuries. Whether you come for the nature trail, the birdwatching or simply the peace of a Šumava autumn, this place is quietly unforgettable.

Covering 138 hectares and fed by the Olšinský Brook, the pond is framed by rolling forested hills that shift beautifully through the seasons. Spring brings birdsong and fresh greenery, summer draws anglers and walkers to the 400-metre embankment with its open views, and late October sees the traditional fish harvest — a colourful local event held every two years. The northern and western shores are protected as a national natural monument, home to rare wetland species. The whole area has a wonderfully unhurried feel, far from the crowds of more famous Šumava destinations.

• From Hořice na Šumavě — red hiking trail, approx. 9.5 km, moderate difficulty
• From Horní Plané via Hodňov — cycling routes no. 1254 and 1255; the Hodňov train stop (line 194) is also a convenient starting point
• From Polná na Šumavě — cycling routes no. 1254 or 1255

• A 7.5 km nature trail loops around the pond
• The historic 15th-century fishing bastion on the dam houses a permanent exhibition on fish farming and regional history, open since 2009
• Traditional fish harvest takes place every two years in late October

In 1790, the dam burst and the floodwave reportedly reached all the way to Prague — earning the pond its dramatic local nickname: 'The Killer as far as Prague'. That story alone makes standing on the restored embankment feel just a little bit thrilling.
