Local tip
Bring binoculars. Winter is great for big flocks of wildfowl.

Cors Ddyga, near Pentre Berw and Gaerwen, is a restored wetland of reed beds and wet grassland. A 1.25-mile trail runs through it. In winter look for flocks of lapwing and hunting marsh harriers; in spring, listen for booming bitterns. Otters and water voles live here too.

Good to know

No toilets on site (nearest in Llangefni). Dogs only on public footpaths and cycle paths, not on the RSPB trail. A short section is accessible for wheelchairs and pushchairs. The Lôn Las Cefni cycle path runs through.
