Llantwit Major is a beach of rocks and some low tide sand at the end of the Col-huw valley. The surrounding cliffs consist of alternating layers of limestone and shales, and are very unstable. A car park overlooks the beach with further parking available on grass. Facilities include picnic tables, cycle stands, toilets and a cafe. A dog ban operates from 1st May to 30th September, and RNLI lifeguards patrol during the school summer holidays, with some additional cover at weekends being provided by the local surf lifesaving club.
It is a popular windsurfing and surfing beach working best at low to mid-tide, but due to rocks, rips and a hint of localism, it's not an ideal beach for beginners. The cliffs half a mile east of the car park are one of the best sites in Wales for fossil collecting, with gastropods and gryphea being common.
The village of Llantwit Major is just under a mile away and has some good cafes, pubs, shops, a sports centre and a railway station. Parking at both the village and beach is free.
