In reply to Martin1978: just up from Marsden rock, there are a few nice coves, that offer good boudering, traverses ,also very good for dry tooling, the rock is pretty sound (limestone) frenchmans bay is the name for one of these coves.
You can either park in the car park at Marsden then follow the path north for half a mile, look out for a black path leading down the cliff to the sea (DISUSED sewer pipe) the coves are to the left of this.
Alternate my follow the road north fro. Marsden to a busstop on the right, park near here & then walk directly over the field to the cove (shorter)
Have fun.
