Just to flag the rad has now been updated, key paragraph below:
COVID-19 Update: please avoid Stair Hole for the time being. The recent spate of tombstoning and associated accidents at Durdle Door has caused serious concerns to the landowner. Whilst DWS and climbing are clearly very different, from a non-climbers perspecitve they are no different. As a result, for now please avoid Stair Hole for climbing whilst attention is focused on the area to prevent future access issues. This page will be updated once the situation changes.
