Wales' largest natural lake and one of the National Park's most popular attractions.
Measuring 5 miles long and half a mile at its widest point, Llyn Tegid is Wales’ largest natural lake. The lake is a popular place for water sports such as paddleboarding, canoeing, windsurfing and fishing.
Blue-green algae has been identified in parts of Llyn Tegid, Y Bala.
This is a natural occurrence during the summer months under certain conditions. We ask all lake users to familiarise themselves with the safety notices on site before undertaking any watersport activities.
Llyn Tegid has a warden who protects the lake and provides advice to visitors. During busy times of the year, an additional warden is brought in to help.
If you have any questions about using the lake, you can ask the wardens.
No. Barbecues are not permitted on the lake shore.
At times during the summer season, when the weather is warm and the water is still, there will be toxic blue-green algae at Llyn Tegid. Look out for green scum on the surface. Do not touch or enter the water when you see scum on the surface, and inform the lake warden as soon as possible. When blue-green algae have been seen on the lake, the information is shared on the National Park website and on signs around the lake.
You can access the lake from Snowdonia National Park Authority car parks. There are two car parks—one on the lake foreshore and another at Llangower.
Throughout 2022 Natural Resources Wales will be undertaking substantial restoration work on the embankment, over which the path runs. The work is essential to prevent the town of Bala from flooding during periods of high rainfall. More information is available on the NRW website:
