Wales' largest natural lake and one of the National Park's most popular attractions.
Measuring 3.5 miles long and three quarters of 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.
You will need to purchase a permit to participate in water sports such as paddleboarding, canoeing and rowing on Llyn Tegid.
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.
