Jezerní slať is one of the most remarkable raised bogs in the Šumava highlands — a vast, untouched peatland stretching across more than 103 hectares at an altitude of over 1,050 metres. Whether you come for the rare flora, the sweeping views, or simply the profound silence, this place is guaranteed to leave a lasting impression.

The bog sits on the Šumava plateau, less than two kilometres southeast of Horská Kvilda, and its landscape shifts dramatically with the seasons. Spring brings white tufts of cottongrass swaying over vivid green sphagnum moss, summer reveals a soft, carpet-like expanse of bog vegetation, and autumn drapes everything in gold and russet. Winter transforms the whole area into a stark white wilderness — this is one of the coldest spots in the Czech Republic, with average annual temperatures hovering around 2 °C and regularly recorded temperature minima. A wooden observation tower at the edge of the bog offers a wonderful panoramic view over the entire expanse, with the distinctive peak of Antýgl visible in the background.

• Tourist car park on road II/169 between Kvilda and Horská Kvilda — short walk along an access path to a 120-metre boardwalk, difficulty: easy

• The site is Zone I of Šumava National Park — strict nature protection rules apply
• Walking is permitted only on the designated path and boardwalk
• Free entry; observation tower freely accessible

The name 'Jezerní slať' means 'Lake Bog' — a nod to a small lake that once existed here and is now almost entirely overgrown with sphagnum moss, with only a tiny remnant pool of 292 m² surviving in the northwest corner. It is a quiet reminder of the landscape as it once was.
