The Axmouth to Lyme Regis Undercliffs, also often referred to in the singular as the Undercliff, is a 5-mile (8.0 km) long landscape feature, National Nature Reserve and Site of Special Scientific Interest that connects Seaton and Axmouth with Lyme Regis on the south-west coast of England. Like its namesake on the Isle of Wight, this feature arose as a result of landslips, where a slump of harder strata over softer clay gave rise to irregular landscapes of peaks, gullies and slipped blocks. Because of the resulting difficulty of access and change of land use, the undercliff has become densely vegetated, and has become a rare and unusual habitat for plants and birds.
