Douglas Gap (Tower Ridge)

Douglas Gap (Douglas Boulder) on Tower Ridge (Ben Nevis)

The Douglas Boulder, a 200m high semi-cone separated from the ridge proper by gullies on the east and west sides meeting at the Douglas Gap. If climbed from the lowest point by Direct Route (Very Difficult) this offers the most challenging climbing on the ridge. Many parties avoid it, usually by scrambling up East gully (Easy). South-West Ridge (Moderate) to the immediate left of West Gully (Easy) is the easiest face route up the boulder, and a short descent of the same ridge and thence into West Gully is the easiest route down into the Douglas Gap from the top).

The Douglas Gap, where parties avoiding the Douglas Boulder via East Gully join the direct line. Tower Ridge proper is then gained via the 20m "tricky chimney" (p106), which became the crux of the route following rockfalls at Tower Gap on and after 30 July 2011. It is well-polished and the exit is delicate in damp conditions.
