Wild, Welsh wilderness

Glaslyn is Montgomeryshire Wildlife Trust’s biggest nature reserve, an integral part of the Cambrian Mountains. The large expanse of heather moorland, with its associated boggy areas, surround an exposed upland lake. Spectacular views can be enjoyed from the viewpoint.

Best time to visit
Glaslyn can be breathtaking at any time of year, but don’t miss July/August, when the reserve turns purple with the flowering heather. Also look out for the lake’s speciality, quillwort, which often washes up on the lake shore after bad weather.

Why not make a day of it and follow the Glaslyn & Bugeilyn audio trail. To find out more and download the mp3 files, click here.



Please note that the landowner, in agreement with the Local Authority and Montgomeryshire Wildlife Trust, has revoked public vehicular access along the track that leads to Glaslyn Nature Reserve, due to persistent illegal activity in the area. As a result the gate at the entrance, off the road, has been locked with a combination lock. MWT members remain able to gain vehicular access through the gate to the reserve car park but will need to contact the office for the code before visiting the site (Please note that this code will be changed periodically).


Alternatively, limited car parking space is available in the layby by the gate.

Please do not park in front of the gate as access is required at all times for landowner and emergency vehicle access.
