The Around Ostrý vrch Nature Trail is a circular route near the village of Dlhá nad Oravou. Through ten educational stops, visitors learn about the geology of the Klippen Belt, local nature, the history of the village, traditional farming and the region's cultural heritage. The trail follows meadows, forest roads and rural paths around Ostrý vrch (808 m), one of the most distinctive limestone hills of the Orava Highlands. It was opened in 2018 as part of a cross-border project, with information panels available in Slovak, Polish and English.
