The Hintergrat is the classic and most frequently documented alpine route on Ortles. It is a long mixed ridge climb with sustained exposure and sections of scrambling on rock, snow, and ice. The route is generally considered the standard ascent from the south side and is much more serious than a simple glacier walk. Objective hazards include rockfall, hard snow, and rapidly changing weather. Route-finding can be complex in poor visibility, especially on the upper ridge. It is typically climbed with an overnight stay at the Hintergrathütte or a bivouac to break up the ascent.
