Traeth Glaslyn

A good place to see estuarine birds throughout the year with a range of habitats from open water to woodland

A large estuarine site to the east of Porthmadog, part of the Glaslyn Marshes SSSI. It is especially interesting because it provides a good example of seral succession - the habitat changes from brackish open water, through mudflats, marshes and wet grassland to damp alder carr. Excellent views of estuarine birds can be had throughout the year, particularly good for winter wildfowl.
