East Devon & Dorset Coast, World Heritage Site

Jurassic Coastline

Jurassic Coast

The striking red cliffs around Sidmouth were formed in a baking desert some 240 million years ago during the Triassic period of geological time. Huge rivers flowed across a desert, rather like the Nile flowing through the Sahara today. But this all happened a very long time ago so how can you explore the World Heritage Site today?

Your first port of call could be the excellent Jurassic Coast Interpretation Centre on the Esplanade. Sidmouth Museum contains information and holds events exploring the World Heritage Site.

Why not take a walk along the coast path to Branscombe and Beer. Here, younger rocks, the Upper Greensands and Chalk cap the cliffs and the combination has given rise to the spectacular Hooken Landslide. These younger rocks are the source of fine building stones that have been used in the construction of Exeter Cathedral.

The Axmouth to Lyme Regis Undercliffs is one of the Jurassic Coast’s best kept secrets. Taking in a small area of wild coast and hinterland across the Devon-Dorset border, this National Nature Reserve contains an abundance of fascinating geological features, wildlife, and social history. You can read more about the reserve on the Jurassic Coast website.

This year, the Jurassic Coast Trust is proud to team up with Natural England, who manage the reserve, to help bring it to life for our Friends and supporters through a series of three expert-led guided walks between May and September.

All walks are bookable through our online shop, and the funds raised will go to the Jurassic Coast Trust and Natural England to help look after the Undercliffs, and other parts of our World Heritage Site.

Places on each walk are limited, so book early to avoid disappointment. The Undercliffs Reserve is a wild and often remote place, so please read the safety information for each walk carefully prior to booking on. Thank you.
