From the valley head in Ridnaun/Ridanna hike along the path no. 9 through a forest towards the entrance of the Burkhardklamm gorge and continue either along the gorge or on the forest path at your left side to the water barrier of the Aglsboden. From there you can reach the mountain pasture Aglsbodenalm after a walk of 10 minutes on path no. 9.
Alternative: reachable also starting from Maiern/Masseria and following the forest path (1,5h)
