Monmouth Beach is situated to the west of the harbour, extending a kilometre south west of the Cobb wall.
It’s predominately a pebble beach with rocky outcrops becoming more prominent as you move west along the coast. It’s also a good beach for fossil hunters – at the western end there’s a layer of limestone, known as the ‘ammonite graveyard’ or ‘ammonite pavement’, which is famous for the large ammonites it contains. With a bit of patience and some luck, you may well find a small ammonite or two. If you want to be assured of success with your fossil hunting, arrange to go out with a fossil guide. Lyme Regis Museum leads guided fossil walks.
The beach is named after the Duke of Monmouth who landed here in 1685 in a failed attempt to overthrow his uncle, King James II. Twelve local people were hanged on the beach by the infamous Judge Jeffreys as punishment for the failed rebellion.
Adjacent to the beach are holiday chalets, beach huts which are available to hire, a bowling green, Lyme Regis Power Boat Club, the Boat Building Academy, and council operated car parks.
Dogs are welcome on the beach all year round.
