From the Scharnitz Nature Park Info Center, follow the Hinterautalstraße road for about 500 m to the Isarsteig junction. At the end of the Isarsteig you reach the Nederweg, hike past the Scharnitzer Alm and continue to the entrance to the Gleirschklamm. A narrow path leads through the wild and romantic gorge, which is only suitable for sure-footed and experienced hikers. The path continues to a forest road. Turn right here to the Hochwald junction and return to Scharnitz via the Hochwaldweg.
