The crag is accessed by a 10–minute walk northwards from the upper car-park of the Ailwee Cave attraction (see map below). In terms of layout, the centre of Aill na Cronain is the "Skull Buttress" which has a distinctive skull–appearance when viewed from a distance. Its "nose" contains the flat
Skull Slab VD–grade climb. The "East Side" face, and "Far East Side" face, lie to the north of Skull Buttress. The "Butterfly" face, and the "Small Wall" face lie to its south. While most routes are between S and HS, more challenging routes have been put up on the "Skull Buttress" such as
Raven (E3 6a),
Monkey Business (E2 5c), and Sunbane (E1 5c). Just over 23 kilometers to the southwest of Aill na Cronain is the more advanced rock climbing limestone sea–cliff called
Ailladie, which contains some of Ireland's most advanced rock climbs. ==Climbing bibliography==
