Cors Goch

The Cors Goch reserve is one of several lowland fens on Anglesey and you can find it between the villages of Pentraeth and Benllech. The reserve lies in the bed of an ancient glacial lake. Over time, the lakes ancient hollow has filled in with peat, as plant life thrived and died through the past 10,000 years - leaving the fen we see today. Like the other wetlands on Anglesey, Cors Goch is an outlying refuge for many plants more often associated with the fens of East Anglia.

The main access point to the reserve lies at the northeast end of the site. A path runs the length of Cors Goch for about one-and-a-half kilometers and there is a boardwalk through the fen, although this can be uneven when there’s a high water level.

There are no surfaced paths on the reserve and the terrain varies from flat to quite steep.Some uneven short stretches are unsuitable for wheelchairs or prams.

The paths can also get extremely wet and muddy with poor weather conditions.
