After leaving the town of Krimml in the direction of Gerlos Alpenstraße, you reach a junction after approx. 2.0 km on the left leading to the track towards Krimmler Achental. Now follows the most physically demanding section, the ascent along the Krimmler Waterfalls up to the Anna Tunnel (length 300 m, unlit). From there, a hiking and bike path runs parallel to the Krimmler Ache, past rustic alpine meadows and operated huts, to the valley end. From here you have the option to hike up to the Warnsdorfer Hut or cycle back to the 1st junction to take a detour (2.5 km) to the Windbach valley to the homonymous Windbachalm before cycling back downhill to the starting point.
