As the shore is followed south and westwards the cliff line becomes more pronounced with the appearance of the chalk and limestone cliffs of the Isle of Purbeck, so called because it is almost surrounded by water and has very little road access to the rest of the county.

The stretch of coast between the southern tip of the Isle of Purbeck, St. Aldhelm's head, and the resort town of Weymouth has some of the most stunning and important coastal scenery to be found in Dorset. This ranges from the abandoned underground stone quarries of Tilly Whim Caves and Worth Matravers, to the spectacular scenery of Lulworth Cove, a world famous geological and geomorphological site. Between these sites the equally important Kimmeridge Bay is located, with its volunteer marine nature reserve, underwater camera and trail and the type locality for Kimmeridge oil shales.
