Starts 30m beyond Green Gully on Heather Terrace. Tricky route finding. Climb a rocky runnel to an ugly step. Move right and climb a short rib to regain the runnel. Don't carry on up; follow a ramp left across the face to a 10m wall. Either climb this or side step it delicately to the left. Walk uphill and climb several small walls on their left. When the Terrace Wall is reached move left along its base and climb rock steps and a chimney to reach North Gully. Either climb the gully to the North Ridge or just take a direct line to the right to reach it.
