The Punkva Cave
The Punkva Cave, which is part of the larger Moravian Karst, is one of the most well-known in the Czech Republic. During the journey, you will first see at the bottom of the Macoacha Abyss, which is 138 meters deep, and then board a boat and go down the subterranean river Punkva. It's a magical experience filled with strange insights into the illuminated and unlit depths of water and rocks. Because the trip is quite popular, it is best to reserve ahead of time.
In the spring and after heavy rains, there is sometimes so much water in the Punkva that boats only traverse a short segment of the path, or trips are canceled; if this happens, admission is decreased. Boat rides, on the other hand, are an essential feature of conventional excursions; for example, it is impossible to visit the Masaryk church in any other manner.
Location: north of the city of Brno, near the town of Blansko, Czech Republic
