Tower Ridge, Ben Nevis, Scotland
Approaching the Tower - The steep section before the ledge in front of the Tower.
The tunnel - When faced with a seemingly impenetrable tower, go round the North East corner to access the Eastern Traverse, to enter and climb through the tunnel.
Summating the Great Tower - From the small belay ledge after the slot, climb the vertical wall on this very exposed (crux) part of the climb.
The top of the Great Tower - At this point the ridge narrows until you face Tower Gap.
