Number 4 Gully is the most frequently skied couloir on the north face so access through the top cornice usually isn’t a challenge. Climbers also use this couloir for a descent route after summiting the Ben via a more technical route and therefore the cornice usually has a slot cut out of it which allows you to safely drop/ski into the couloir itself.

Be aware - if the couloir hasn’t slumped yet (during spring), or a slot hasn’t been cut out then the cornice can soon becomes the crux of the route, with huge drops down onto the 45 degree pitch below making entering this gully almost impossible for all but the crazy - make sure you climb up the gully if unsure about how you’re going to get into the gully.

Once in the gully, you’ve got a short yet very steep top section that is wide open without any obstructions. Once this steep section is passed, the gully then funnels in a very short bottleneck and once this bottleneck is passed, you’re then through the technical sections of this ski which leads you out onto the Corie na Ciste where you’ll get to open out the turns a little more all the way back down to the CIC Hut.
