About this site
The Runnel Stone is a reef in Cornwall where the wreck of the City of Westminster lies scattered through a few gullies and around the rocks. A drop-in at around 15 metres leads down to 40 metres and beyond.
Huge boulders form the reef, and the wreckage is spread out among them, with large sections visible as divers move around the reef. Visibility of 20 metres or more has been reported.
