Visiting

The Bendricks can be accessed via a path which follows the outside of the security fence round HMS ''Cambria'' at Hayes Point, Sully or by following the coastal path in a south-westerly direction from the public slipway at the

recycling centre at Hayes Road, Sully. The footprints can be difficult to see. Many are covered at high tide so it is easier to see them after high tide when the tracks may retain small puddles of water. It is also easier to spot the footprints when the sun is low in the sky as longer shadows will help throw the footprints into relief. There is a small residential street known as Bendrick Road, consisting of around 50 houses.
