Educational Trail by the Lakes of Párnica Beautiful lakes can be found near the village of Párnica, formed in the former gravel pits, now creating an oxbow lake of the Orava River. This area has developed into a fascinating ecosystem, recently inhabited by beavers. To make this hidden gem more accessible, an educational nature trail was built in 2016. The trail is 1.5 kilometers long and takes about 30 minutes at a brisk pace. If you take time to read all the informational panels about local plants, animals, and other natural features, the walk may take up to 1.5 hours. The path is also welcoming to cyclists.
