★★★ Integral Crack 20

One of the absolute classics. Considered by many to be the best line at Booroomba, noting that much of the climbing is actually face climbing rather than pure crack. Excellent natural protection. Start eight metres left of Marmalade at the slabby crack. Take lots of wires and some medium sized cams to belay. There is a rap station off to the right, above Dangermouse.

The ethic at Booroomba is generally staunchly traditional. Most climbing goes either entirely on gear or gear with bolts for those walls where there is insufficient gear to protect climbs. Climbs are occasionally rebolted, but retro-bolting would be considered vandalism of the lowest order.
