★ Kass 21

Start 2m L of 'Bombadil'.

First top roped as 'Kasper' in the '70s at grade 16, the passing decades and a passing Bosch have seen it evolve into a grade 21 sport route. 6 RBs, chains.

A DBB at the 4th bolt allows it to be climbed in 2 (admittedly very short) pitches, great for practicing multipitch skills in a safe environment.

Climbing at 'KP' has a long, rich history and the cliffs are used by a huge number of climbers of very varied styles and abilities. For these reasons ethics here are complicated. However here are some undisputed points:

• All top roping should be done through your own quickdraws to minimize wear on the anchors.
• Don't ever chip holds.
• Don't paint on any new initials.
• Retrobolting is acceptable only after consensus is reached with a large cross section of the 'KP' climbing community. New bolts that don't meet this criteria are chopped, often within a few days.
