The Jurassic Coast - 185 Million Years at Your Doorstep

What is the Jurassic Coast?

The Jurassic Coast is a 95 mile stretch of coastline running from Oremouth in East Devon to Old Harry Rocks near Swanage in Dorset. It was designated a UNESCO World Heritage Site in 2001 - the first natural site in England to receive the status - because its exposed cliffs and beaches contain a near-continuous record of 185 million years of geological history, from the Triassic through the Jurassic to the Cretaceous periods.

In practical terms, this means the rocks change as you travel along the coast. The red sandstone cliffs in East Devon give way to the dark grey limestone and shale around Lyme Regis, then the white chalk cliffs and dramatic arches of the Purbeck coast. Walking the coast path is like walking through a geological textbook.

Why Weymouth is the Best Base

Weymouth sits roughly in the middle of the Jurassic Coast, which makes it an ideal base for exploring in both directions. From The Escape, you can drive east to Lulworth Cove in 20 minutes, or west to Lyme Regis in 45 minutes. Every major attraction on the Jurassic Coast is within an hour's drive.

Weymouth also has one of the best beaches on the coast, meaning you get the heritage and geology during the day and a sandy beach on your doorstep every evening.

Key Stops Along the Jurassic Coast

Here are the highlights, ordered roughly east to west from Weymouth:

• Lulworth Cove (12 mi east) - the near-perfect horseshoe bay, Stair Hole, fossil forest
• Durdle Door (13 mi east) - the iconic natural limestone arch
• Kimmeridge Bay (15 mi east) - rock pools, fossil hunting, the Etches Collection museum
• Old Harry Rocks (25 mi east) - chalk sea stacks marking the eastern end of the World Heritage Site
• Chesil Beach (2 mi west) - an 18-mile pebble bank connecting Weymouth to West Bay
• West Bay (15 mi west) - the harbour from Broadchurch, dramatic sandstone cliffs
• Charmouth (25 mi west) - one of the best fossil-hunting beaches in Europe
• Lyme Regis (30 mi west) - the Cobb, fossil museums, Mary Anning country
• Beer (45 mi west) - a fishing village with cave systems and a pebbly beach backed by chalk cliffs

Walking the Coast Path

The South West Coast Path runs the full length of the Jurassic Coast and beyond. You don't need to walk the whole thing - many of the best sections are short enough for a morning or afternoon walk:

• Durdle Door to Lulworth Cove - 1 mile, 30 minutes each way, steep but spectacular
• Weymouth to Osmington Mills - 4 miles, 2 hours, cliff-top views and a pub at the end
• West Bay to Seatown - 3 miles, 1.5 hours, Golden Cap (the highest point on the south coast)
• Lyme Regis to Charmouth - 2 miles, 1 hour, through the Undercliff landslip
• Dancing Ledge to Chapman's Pool - 3 miles, 2 hours, remote Purbeck coastline

All of these walks start from car parks or villages with facilities, and most can be done as out-and-back routes, so you don't need to arrange transport at both ends.

Fossils

The Jurassic Coast is one of the most important fossil sites in the world. The cliffs and beaches between Lyme Regis and Charmouth are the richest hunting ground, where ammonites, belemnites and occasionally larger marine reptile bones wash out after storms. Kimmeridge Bay is another good spot.

You can pick up loose fossils from the beach - this is legal and encouraged. Never dig into the cliffs or use hammers on the rock face. For the best experience, join a guided fossil walk. Local experts know where to look and can help identify what you find.

Geology for Non-Geologists

You don't need to know anything about geology to enjoy the Jurassic Coast. The landscape speaks for itself - the natural arches, the folded rock layers at Stair Hole, the colour changes in the cliff faces as you travel along the coast. But if you want to understand what you're looking at, the visitor centres at Lulworth Cove, Charmouth and Lyme Regis have free or low-cost exhibits that explain the geology clearly.

The short version: the oldest rocks (250 million years) are in the east at Exmouth, and the youngest (65 million years) are in the west at Old Harry Rocks. Weymouth sits on the Jurassic limestone - the layer that gives the coast its name.
