Sennen is near Land’s End and is the westernmost of our locations.

 This west facing beach is split into two, Sennen Beach to the south and Gwynver Beach to the north, by a rocky outcrop. Both are wide and gently sloping. The sand is medium grained with quartz and shell particles with little lithic content.

 The cliff behind the dunes is steep and eroding with exposed granite boulders within the glacial Head material resulting in these boulders forming a natural rock armour at the foot of the cliffs.

 Dune development is constrained by the steepness of the cliff behind, except in the stream valleys. The dunes are clean and healthy where present.
