In a glimpse:

• Start: Steingletscher, Sustenpass
• Duration (ascent only): 2 ½ hours from the road's end, add about ½ if starting in Steingletscher
• Difficulty: T3 - Challenging Mountain Hikes (even though the trail is marked with blue-white, I consider a rating of T4 - Alpine Hikes would not be justified)
• Last done: August 2000
• Local weather forecast: Engelberg, #0900-57306x 282; Grimsel, #0900-57306x 290; Guttanen, #0900-57306x 295
