Llangorse (sometimes Llangors) is situated in Powys, Mid Wales. The village lies to the east of Brecon in the Brecon Beacons National Park. The B4560 passes through the village, running to Talgarth in the north and Bwlch in the south, whilst the A40 road passes close by.

The landscape around Llangorse is criss-crossed with trails and public rights of way. With trails for both walkers, equestrians, and mountain bikers Llangorse is a popular holiday destination.

Llangorse Church, dedicated to St Paulinus, has some magnificent Tudor doors and windows, and includes a barrel roof. However, the real point of interest in the village is Llangorse Lake.

Also known as Llyn Safaddan, the lake is the largest in South Wales and the second largest in Wales after Bala (Brenig Lake). It has a circumference of 5 miles, is one mile long and 154m above sea level. It is also the site of a crannog, an ancient artificial island. Although popular for its water sports and angling, Llangorse Lake also attracts visitors because of its association with folklore. The lake has been mentioned in many Welsh mythical tales, and is home to its own mythical creature, Gorsey the afanc (a Welsh lake monster).

Centuries ago, Milo, earl of Hereford, Payn Fitz John and Gruffydd ap Rhys were walking past the lake on a day when it was abounding with birds. The knights had heard that the birds of the lake would sing when the rightful lord of Wales came to bid, so all three broke into song. Unsurprisingly, nothing happened and the three knights were forced to continue on their way.
