Trecco Bay Holiday Park is a large caravan and holiday park operated by Parkdean Resorts, situated directly beside Trecco Bay beach in the seaside town of Porthcawl, South Wales.

It is widely cited as the largest holiday park in the UK and among the largest in Europe, with over 2,000 caravans on site. The park sits between Newton Beach to the east and Sandy Bay to the west, giving guests easy access to the South Wales coastline.

On-site facilities include a Splashland swimming pool, amusement arcades, mini golf, and public toilets, making it a popular destination for family holidays.

The adjacent beach itself has no dedicated facilities, but the park serves as the main hub for visitors to the area.
