A truly great climb up the middle of the Watchtower.
Many variants are possible in the middle section and many parties do the Minerva variant (described separately)
Start up the right-hand of the two deep cracks at the base of The Watchtower. This is just left of the undercat section and 9 metres right of the start of The 'Watchtower Chimney'.
1) (40m, 8) Up deep crack until it ends. Traverse 4 metres right, up over disconcerting bulge and follow crack to large ledge. (The first ascent traversed all the way to the right arete befor climbing bulge).
2) (21m, 8) Either climb up left of the belay or climb just right of the crack until below bulge and then step left over the crack.Belay on narrow ledge below overhang on left side of The Watchtower.
3) (14m, 9) Either climb straight up veering slightly right, or traverse right on smooth rock past ancient piton before moving right. Belay in a good cave on the right side of the buttress.
4) (30m, 8) Move left out of cave and up exhilirating wall to top. Prearrange your signals as communication is likely to be impossible from the top.
