Portland Cherty Series and through the Portland Freestone. Fallen blocks of stromatolitic limestone come from the basal Purbeck Formation above. Ammonites can be seen, various features of silicification are clear, sponge spicules can be seen in the chert, bivalves in the Portland Freestone are common. There is a small karstic cave and interesting travertine features. Cave development by the sea can be studied. To the east of Dancing Ledge is a significant fault affecting the cliffs and the topography just inland. A dry valley with hillwash deposits descends to the quarry, and the topic of former water flow in the area is of interest. Jointing in the Portland Stone can be studied and assessed by statistical methods as part of a student exercise.

Dancing ledge is well known by both walker and climber and is great for both. A sport climbing quarry and some steeper routes on the sea-level roofs. Easy access and non-tidal. Often busy and popular with beginners. Some bouldering areas. Dancing Ledge is part of the great Swanage expanse of limestone situated about 10 to15 minutes walk from Tom's Field. Dancing Ledge is approached from Langton Matravers. To reach the parking spot, turn off the A351 towards Langton Matravers, just outside Swanage town. Once in the village, go past the post office and turn left into Durnford Drove. The free car park is 300m down here by Langton House. From the parking walk south on a good path past four fields and a spyway barn. After the 4th field head down a big hill towards Dancing Ledge which lies directly below the coast path. From here steps lead down into the quarry.
