Book Tickets Online


Llangorse Lake in the heart of the Brecon Beacons national park, is the largest natural lake in south Wales. It boasts an ancient Crannog and is a perfect location to mess about in boats, take a gentle stroll or watch wildlife.

Llangorse Lake is a glacial lake formed thousands of years ago when moving ice pushed and scraped its way along, shaping the landscape that we see today. On its journey it collected piles of debris (mud, rocks, wood and stones) which were deposited to the front and side of the glacial movement. When the ice finally melted this debris was left to form mounds known as moraines. Llangorse Lake owes its existence to the moraine deposits left in the area between Llanfihangel Talyllyn and Talgarth. At one time it was some 150 foot (45 meters) higher with two overflows into the Usk River at Bwlch and Pennorth.

The entire lake's surface and the adjoining common is registered common Land giving local people ancient rights to graze their livestock upon it.

Fishing at Llangorse Lake

Llangorse lake is one of the best pike fishing lakes in Wales. It is the only place in Wales where the rare Two-Toned Reed Beetle can be found and there are three oak trees which were probably planted when Queen Elizabeth 1 was on the throne. The oak trees can be seen along the walk from Llangorse common to the bird hide and are easy to spot from the huge trunks they have developed.

Treberfydd House has been the film location for several Dr. Who series. The Gate Shop dates back to the 1700's when it was a toll house. Anyone wanting to pass through the gap (Bwlch) in the mountains had to pay a toll.

Walking Trails

Nearby Bwlch is home to three circular walks; Bwlch with Altitude, Bwlch with Fortitude which leads to Tretower Court & Castle and Bwlch with Magnitude, taking you on a magnificent ascent of Tor -Y-Foel.

Dark Skies / Stargazing

Llangorse Lake has a  profusion of places to set up telescopes. It shares the location with an outdoor pursuits centre, which has some stray light but with a limiting magnitude of 6.24 which shoud make little intrusion into this beauty spot.
