Highlights of the Jurassic Coast

This full-day private tour from the Isle of Portland explores the Jurassic Coast, a UNESCO World Heritage Site inscribed in 2001 that runs 95 miles between Exmouth in East Devon and Studland Bay in Dorset. Today's visit focuses on Durdle Door, Lulworth Cove, the harbor town of Weymouth and Chesil Beach.

After meeting your local guide at the port, you set out along a coastline known for its geology as well as its flora, fauna, birds and marine life. The Jurassic Coast takes its name from the Jurassic period and exposes rock layers spanning roughly 185 million years of Earth's history, from the Triassic through the Cretaceous.

Your first stop is Durdle Door, a natural limestone arch cut from Portland Stone dated to roughly 140 million years old, one of the most photographed landmarks on the coast. From there you visit Lulworth Cove, a horseshoe-shaped bay carved by wave erosion, with clear water that makes it a popular swimming spot in warm weather; there is time to explore the small fishing village here as well.

Later in the morning, you stop at the ruins of Corfe Castle, set on a steep hill above the village of Corfe. Building began shortly after the Norman Conquest of 1066 under William the Conqueror, making it one of the earliest castles in England to use stone rather than timber and earth; the great stone keep was completed later, in 1105, under his son Henry I. The castle remains a popular attraction today, drawing visitors to explore its medieval remains and take in views over the surrounding countryside.

In the afternoon, you stop in the old harbor town of Weymouth, with time for lunch on your own (meal not included); fish and chips with a sea view is a popular local choice. King George III first visited Weymouth in 1789 to recover his health and returned many times over the following years, helping establish it as one of Britain's first fashionable seaside resorts. During WWII, Weymouth Harbour also served as a major embarkation point for Allied troops heading to the D-Day landings in June 1944.

Before returning to the pier, you stop at Chesil Beach, an 18-mile shingle barrier beach running from West Bay to the Isle of Portland, a good spot to take in views of the coastline before the tour ends.
