Llynfi Holiday Park is a flat, well-sheltered grassland park set within the Brecon Beacons National Park in Powys, Wales, close to Llangorse Lake.

The site is a short walk from the lake's shore, where visitors can access water sports, fishing, and a historic crannog. It is located approximately 4 miles south of Talgarth on the B4560 and 5 miles east of Brecon.

The park accommodates tents, touring caravans, motorhomes, and privately owned holiday homes.

Facilities include a sanitary block with showers, toilets, shaving points, and hairdryers, along with a laundry room, chemical disposal point, electric hook-ups, and a bar and clubhouse.

It operates as a family-only site, and dogs are not permitted on touring or tenting pitches.
