Llanddulas Beach is mostly rocks and the remains of wooden groynes, with some sand showing at low tide. It is backed by a cycle path, with the main railway running just behind. Just to the east, the river Dulas (which is more of a stream) meanders through a grassed area, before emerging onto the shore. Two (free) parking areas overlook the beach, and are just a few hundred yards from the Llanddulas junction of the A55. There are toilets here, but no other facilities. Access to the shore is down a slipway and dogs are allowed at all times.
