Llanelli Beach is a small beach of mostly course sand backed by a sea wall and low dunes, with stone breakwaters at each end. Behind the beach is a P&D car park and a cycle path which continues along the seafront to Pembrey. The beach looks out towards north Gower. East of the main beach are more small sandy beaches separated by breakwaters which are quieter and more sheltered. Dogs are allowed at all times.
There are good facilities here: the building behind the beach houses a Tourist Information Centre, a cafe with balcony seating and toilets. Signs at the beach warn against swimming. Other hazards lower down the beach include sandbanks which reach miles out into the bay and areas of sinking mud. Water quality may be poor after periods of heavy rain.
