The Smoking Room climbs up and right through a bulge onto a huge stalactite feature and then up that for a way to a ledge and anchor above. The crux is a tricky section that climbs steeper than it looks, owing to some traversing movement. This is one of the better climbs on the wall and deserves to be done.
Location
As you reach the Melting Wall through the arch from Fire Wall, turn around and look on its right side. The bolted line starting just to its right and finishing above the path is Bon Soir. Starting just right of this, the rightmost route is 'The Smoking Room.'
