Weymouth Jurassic Coast Adventure

Walk from Weymouth station to the King’s Statue bus stops and take the Jurassic Coaster X54 to West Lulworth/Lulworth Cove. Start at Lulworth Cove Visitor Centre for animated displays explaining how this World Heritage coastline formed. Then head to Lulworth Cove, where the perfectly shaped horseshoe bay comes into view, formed by the power of the sea breaking into a hard limestone rim and eroding the softer rock layers behind the narrow entrance. The cliffs here tell a story of 80 million years of earth’s history, a continuous record from Jurassic Limestones through to Cretaceous Chalk. A short walk to Stair Hole offers views of the “Lulworth Crumple”, intensely folded and contorted sedimentary rock layers, showing how earth movements squeezed the rocks long after they formed. For an extra stop, the Fossil Forest to the east marks the Jurassic Cretaceous boundary, around 145 million years old, with algal burr circles and steep steps down and back up. Check tide times before exploring any shoreline/ledges and note the Fossil Forest lies within the MOD Lulworth Ranges, so access is only possible when the ranges are open.

In the afternoon, walk the South West Coast Path from Lulworth car park to Durdle Door (about 1.7 km). As the path rounds the headland, Durdle Door comes into view, a sea arch cut through steeply titled Portland Limestone, laid down in warm Jurassic seas 150 million years ago. The arch itself is only about 10,000 years old and is shaped by the relentless erosion of softer rock, representing an ongoing geological process where the arch will eventually collapse, leaving a simple sea stack. Continue down to Durdle Door Beach (the decent is steep, so sturdy footwear helps), a wide expanse of smooth pebbles and sand. This is a great opportunity to take a swim in the famous turquoise waters. Finally, walking west along the cliffs (towards the aptly named Scratchy Bottom) one can spot small fossil bivalves in the grey-green rocks. These delicate fossils are best left in place for others to see.

Return to Weymouth on the X54 and spend the evening along the historic harbourside and esplanade. This is a great moment to link the day’s landforms back to the wider Jurassic Coast story and plan tomorrow’s island circuit on Portland.

From Weymouth, head by bus towards the Isle of Portland, this land-tied island marks the southernmost point on the Jurassic Coast and is joined to the mainland by Chesil Beach. Stop at the Fine Foundation Wild Chesil Centre for interactive displays on wildlife and geology, plus views across the landscape. Chesil Beach is a vast ridge of shingle piled up by waves and storms, stretching for miles and forming a natural barrier that shelters the calm waters of the Fleet lagoon behind it – great day out if interested in bird life, with boat trips during spring and summer. From the centre, either walk or hop back on the bus to head for the South West Coast Path Isle of Portland Circuit (20 km), starting near the Heights Hotel. This route will take you around the entire Island. Head via Tout Quarry to the western cliff path, the island opens into big scenery and old quarry tracks. This is classic Porland Stone landscape, created in warm Jurassic seas and later quarried into the building stone used across Britian. Follow the clifftop route south with long views over Lyme Bay, aiming to reach Portland Bill by late morning.

Continue south to Portland Bill, where the coastline narrows into a dramatic headland. Explore the headland for great views of ledges, coves and the powerful Portland Race waters that once hampered the advance of the Spanish Armada. This is a perfect spot to stop for lunch. If you have time, you can visit Portland Bill Lighthouse and visitor centre. When you are ready, continue on the path around the island, this time heading north along its eastern side. Plan a short stop at Portland Museum near Church Ope Cove to connect the scenery to people and history: the museum packs in stories of dinosaurs and fossils, shipwrecks and smugglers, and Portland’s stone industry. If you want to end at Portland Bill, there’s a seasonal Portland Coaster service branded as 501 that runs between Weymouth King’s Statue and Portland Bill.

Whether you finish your loop near the Heights Hotel or all the way back at Ferry Bridge (right by the Wild Chesil Centre), you’re perfectly placed to hop on First Bus Route 1 back into Weymouth for a well earned rest.
