Welcome to Llangorse & Bwlch


Llangorse has 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 the bird life.

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 feet (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.


Bwlch has castles, ancient iron age forts and standing stones, not to mention 360 degree views across the lake.

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

All have their own dedicated maps and leaflet.
