What to Expect at Soos National Nature Reserve

The Soos National Nature Reserve covers about 221 hectares of protected land. It is famous for its peat bogs and mineral springs. The ground is covered in a white crust of salt and minerals. This gives the park a very strange and beautiful look. It feels like stepping back millions of years in time.

The main attraction is the 1.2-kilometer nature trail. It is built on a wooden boardwalk to protect the fragile ground. This makes the path flat and easy to walk. You do not need heavy hiking boots for this trip. Sneakers or comfortable walking shoes are usually enough. The air often smells slightly of sulfur from the natural gases.

This park is a great escape from the busy streets of Karlovy Vary. It is quiet and full of natural sounds. You might hear the soft popping of gas bubbles in the mud. The reserve is also part of a wider region recognized by UNESCO World Heritage Centre for its spa history. Visiting Soos adds a wilder side to your Czech holiday.
