A cliff intersecting the couloir forced the two to make an abseil. There is a bolted abseil descent route off Nelion. In climbing, they are used to construct leave-in-place abseil anchors. However, the southernmost sections are all sea-cliffs and can only be accessed by rope abseil. Participants abseil down from the pyramid roof to street level. This follows an option to abseil down the tower, introduced in 2014. The lighthouse was the site of charity abseil events in 2009, 2011 and 2013. Some difficulties can be avoided by means of an abseil. There were two 60-meter abseils and one 140-meter abseil. Shaun easily grabbed a case on his abseil. Jan was first, on a 60-meter abseil, but could not retrieve a flag. They could only abseil once each, and retrieve one flag each. She realises to her "dismay" that the only other doctor who can abseil is Dylan.
