The Skerries

The Skerries are a group of small granite islands off the northwest coast of Anglesey, shaped over time by the relentless action of coastal erosion. The site spans about 17 hectares and includes several interconnected rocky outcrops and smaller islets.

A lighthouse was built on these rocky islets in the 1800s to guide ships safely through the treacherous waters around Anglesey. This structure became a key landmark for maritime navigation in the region.

The Welsh name Ynysoedd y Moelrhoniaid means Islands of the Seals, reflecting how local communities have long connected these rocks with the marine life swimming around them. Today the site remains closely tied to wildlife watching and seasonal breeding patterns.

The islands are reachable by charter boat from Holyhead, with local operators familiar with tides and weather conditions. At low tide, visitors can wade between some islets, but timing is important and advance planning is essential.

The site hosts a significant Arctic tern colony each summer when these birds arrive from distant northern regions to breed. These remarkable birds transform the rocks into a bustling nursery during their seasonal visit.
