Very long hike that requires good physical condition and for the summit climb a head for heights and absolute surefootedness. To save time, it is recommended to go by bike to the Kastenalm.
From the nature park information center, follow the Hinterautalstraße to the Gleirschhöhe. From there, take the left forest road in the direction of Isarursprung/Kastenalm. Park your bike just before the Kastenalm and go over a small bridge to the right, then go steeply uphill past the Lafatscher Niederleger to the Halleranger. Once you reach the alpine pasture, the trails split. At the junction, keep right until you reach the Hallerangerhaus. At the house again keep right and follow the path up to the Lafatscherjoch. From there, a narrow, initially easy trail leads to the left towards the west ridge of the Speckkarspitze and later in easy climbing (1+) over the connecting ridge and short exposed passages to the Speckkarspitze. The descent takes place over gravel, scree-rich, partially secured with wire ropes in the direction of the ascent route below the Lafatscherjoch. Return to the starting point along the same path.
