Harlech Beach is sandy, 4 miles long and backed by dunes and a golf course. The sand is fairly coarse and of a light colour, which makes the beach stand out when seen from a distance. Bathing is generally safe, apart from the north end near the Glaslyn estuary where there are strong currents and sandbanks. Windsurfing is popular here. Parking is at a P&D car park, which has (seasonal) toilets, cycle parking and usually an ice-cream van in summer. Access to the beach is along a tarmac path (about 400 yards) which leads most of the way across the dunes to the beach. Dog restrictions apply to the north of the main access point for a distance of about 500 yards, from April 1st until September 30th.
Harlech's rail station and swimming pool are both about ½ mile away.
