The new edition of the Climber's Club Ogwen guide is a thorough reassessment of the climbing on the south side of the A5, centred on the ever-popular Tryfan and Cwm Idwal. The guide includes 140 new routes climbed since the last guide, and many ‘rediscovered’ older climbs. The new routes cover the spectrum of grades and are on both old and new crags. Among the new crags are the Eastern Cliffs of Gallt yr Ogof; this includes Skyline Buttress, the location of some of the hardest rock climbing in Wales such as the E9 Mission Impossible. Usefully, particular attention has also been given to highlighting some of the easier climbs, which are now often climbed as scrambles.

The guide now also includes the climbing on the north side of the A4086 between Pen y Gwyrd and Capel Curig, and for the first time the excellent climbing on the Creigiau Llynnau Mymbyr (the Ricks and Racks) is described in detail. These crags have been climbed on for years by Plas y Brenin parties.

The Climber's Club Ogwen guide has many action photos, all-colour photodiagrams, and photoplans. The bouldering sections have been written by Simon Panton.

The guide also has a chronology (a combination of the historical and first ascents sections), which includes short biographical notes on the leading activists over the years. A graded list of climbs in the Ogwen area has been included for the first time.
