Haystacks is most often climbed from Buttermere, either via the Scarth Gap Pass to the west, or Warnscale in the east. These can be combined to give a fine circuit. A longer variation of the Warnscale route via Dubs Quarry is also possible. Dubs can also be reached from the summit of Honister via the Drum House, significantly reducing the ascent required. Scarth Gap can be reached from Ennerdale to the south, particularly if staying at Black Sail Youth Hostel. Longer outings take in Haystacks indirectly from Brandreth or High Crag.
