The Isis Buttress is a sub-section of the Book, and lies between two deep clefts on the climbers left side of the Book. The cleft to the left of Isis Buttress is the Renaissance Wall. To the right of the Isis Buttress lies the Pages Wall Area (the cleft to the right of Isis Buttress proper is included in this section). This area sports some testpiece Lumpy climbs including the Living Dead (5.11b) and Dead Boy Direct (5.11d), as well as a few classic moderates like Isis (5.10b) and Ramses (5.10c).
Hike as you would to the Book, but trend left when you reach the base of the Pages Wall. After passing a series of beautiful vertical cracks on the left side of the Pages Wall Area you will find the first cleft on your right and then the Isis Buttress just before you.
