Cheyne Cliff is the highest on the east coast of Portland and contains a number of the Isle\'s finest steep wall pitches. The routes mostly fall into the mid to upper 7th grade and are both long and fingery with a good proportion of the climbing being on flowstone faces and orange coral sheets. The harder routes have been used for training purposes and many variations have been done over time. The Nook is a very different proposition having some short and well sheltered lines in the lower grades.
