Crantock is located on the left bank (south) side of the Gannel Estuary, south and west of Newquay.
Coastal sand dunes are in a highly dynamic environment with interaction with sediment movement within the mouth of the Gannel Estuary.
The back dunes are relatively healthy with vegetation, bare hollows and dry dune slacks. In the west, the dunes are very high and steep. A stone wall was exposed in 2020 and is thought to be a 19th Century boundary.
Centrally, the dunes are more stable but there is still over-steepening of the active face and excessive vegetation loss.
Toward the east the dunes are in a generally unstable condition, being part dune and part rock cliff. Dunes are cliffing and overhanging rock caves, with safety implications.
Further east the dunes are less steep and the active face more stable.
There are high recreational/tourism pressures on the system.
