The Routes

  1. My Favourite Colour - E4,6a
    Start from a flat back ledge 12m above the zawn bed above the jammed boulder. Scramble up a mucky rift, then access the pink soaring crack. Exit right from this. 10m.

  2. Spacetalk - E2,5c
    From the top of the rift take the handrail rightwards to a commiting move onto a triangular hold gains the top.

    The next two routes start from the jammed boulder. 10m.

  3. Pop Idol - E5,6b ***
    Swing right into the right-hand of two cracks. Climb this until it closes then undercut left to and into overhangs. Pull up, PR into a pink groove and follow this to the top. 18m.

  4. Pop-Eyed - E4,6a **
    The crack and roofs right ot Pop Idol. The first ascensionist route description makes no sense, so good luck! 18m.

  5. Splash And Grab - E6,6b *
    The tapering wall to the right. Swing right from the boulder and move down the right hand crack to a horizontal break. Follow this right for 2m. Follow the black face above, trending slightly right to the left hand side of the arête (hex). Reach left to good holds and pockets in the thin upper wall. Gear is very specific. 18m.

  6. Sinister Sister - E4,5c
    Follow the arête 5m right of the jammed boulder to the break. Arrange protection and continue up the arête and groove, TR. 21m.

  7. Wiggly Woo - HS,4b
    Climb the gully and obvious narrow pillar right of Sinister Sister. Some poor rock. 21m.
