Difficulty: Mostly easy until final ascent, then moderately difficult (sure-footedness and no vertigo problems recommended)
The trail to the Niederl is a part of the Stubai high trail and it leaves Sulzenauhütte in an easterly direction over the Sulzauer stream via the footbridge. There follows a 50m hike into the basin of the Freiger glacier (Seitenmoränen, Stirnmoränen). It continues further over the Grünau river up the moraine until Grünausee. Then a sign points us in a north-easterly direction to the next fork in the trail (Niederl-Mairspitze). From there, the trail traverses a softer landscape past more mountain lakes. After approximately 20 minutes of walking, it becomes moderately steep before becoming even steeper as it serpents up the mountainside to the saddle on the ridge. On the other side of the ridge it is possible to descend to Nürnbergerhütte. This trail is no more difficult than that from Sulzenauhütte.
