Get to the CIC hut (choice of approaches, check the map, OS sheet 41 or the laminated Nevis and Glencoe map). Head up into the left side of coire na ciste as seen from the hut. Garadh Gully is the obvious snow/ice couloir which seperates Tower ridge on the L from the smaller Garadh na Ciste on the right.
Access to coire na ciste is guarded by a slabby rock barrier with a gorge at the LH end. Either skirt the gorge above on its left or scramble through the rocky barrier on the right, don't go up the gorge.
Once over the barrier head up to the base of the couloir.
Climb the gully, over 1 or 2 short ice pitches (can be longer and harder in early season)
From the platform at the top No.2 gully is the obvious gully splitting the cliff headwall to the L of Comb gully buttress. It's not the one tucked against the big cliff on the right (the comb) that's Comb Gully.
No.2 is mostly 50-55 degree snow. Pass the cornice out left
1 or 2 tools, crampons, a few slings and nuts, maybe a couple of pegs and a couple of ice screws. No need for any more
