As you come into Sharpness Docks, turn right at the mini roundabout, follow the road round and over the swing bridge and take the second on the right, by the Sara Lifeboat sign. You will need to park at the bottom of the unmade road and walk up the hill past the Dockers Club (which will be on your right), then come back down the hill, and as you walk through the car park you will find a steep path and some steps down to the marina.
