Long Hole Cliff is named after a small cave in the centre of the reserve, which during nineteenth century archaeological excavations yielded Stone Age tools and the fossil remains of Ice Age animals which can be seen in The Royal Institution in Swansea.

Parts of the cliffs closest to the sea in the south east corner of the reserve have been quarried for limestone, which was burned in the adjacent limekiln, the ruin of which is still visible, to provide lime for spreading on fields further inland.

The reserve displays a very clear difference in vegetation between the deeper cliff top soils which support Gorse scrub and heath and the thinner soils of the slopes, cliffs and scree with limestone grassland flowers. Spring brings a flush of blue to the cliffs as Spring Squill flowers, followed by a wide range of other flowers including Bird’s-foot Trefoil, Kidney Vetch, and the nationally scarce Portland Spurge.

Weasel is often seen hunting for Rabbits or Voles along the boundary walls.
