Llangorse Lake

Llangorse Lake in the Brecon Beacons National Park is the largest natural water body in south and mid-Wales and a great place for wildlife. With twenty-two species of dragonfly recorded, Llangorse Lake is the perfect place to spot dragonflies and damselflies.


Working in partnership with Llangors Community Council, Brecon Beacons National Park, Wildlife Trust of South and West Wales, and Biodiversity Information Service for Powys & Brecon Beacons National Park. Llangorse Lake was officially designated as a Dragonfly Hotspot in July 2022.

Opening times, entry costs, facilities and directions

There is a large free car park at Llangorse Lakeside with a shop, cafe, toilets and boats for hire during the summer. A trail from here for about 2 kilometres takes you to a small car park at Langasty-Talyllyn; the shop sells a leaflet with map.

Things to see

The Lake is bordered by reedbeds and set among lightly grazed fields including some lovely wild flower meadows good for butterflies. The trail gives access to a bird hide. The best places to see dragonflies are at the water’s edge and the Llynfi outlet stream at Lakeside, in meadows near the bird hide, and along the lake edge at Llangasty-Talyllyn.
