South Stack
Island Sea stack and lighthouse off Holy Island, sharp cliffs
Sea stack and small island off Holyhead, Anglesey, crowned by a 19th‑century lighthouse; popular for cliff walks, seabird colonies (including puffins) and coastal photography.
South Stack (Ynys Lawd area) is a prominent sea-stack and cliff complex on Holy Island off the northwest coast of Anglesey in Wales, near the town of Holyhead. The location is known for a 19th-century lighthouse on the offshore stack and for its high coastal cliffs.
The area is a popular viewpoint for dramatic coastal scenery and for observing seabird colonies that nest on the cliffs, including puffins and other seabirds during the breeding season. Cliff-top paths and viewing platforms provide access to views of the stack and lighthouse.
A lighthouse was established on the offshore stack in the 19th century to guide shipping around the headland; the lighthouse and associated stair access remain the site’s historic features. The cliffs and rock formations are used for coastal walks, birdwatching and photography.
South Stack lies on Holy Island, off the northwest coast of Anglesey, in north-west Wales, close to the port town of Holyhead.
- Birdwatching season: Best known for its dramatic cliffs and seabird colonies, the site is particularly active for birdwatching in spring and early summer when seabirds breed.
- Access notes: Access involves a steep descent from the cliff-top down to the lighthouse path and viewing platforms; care is needed on steps and coastal paths.
What to See #
- South Stack Lighthouse: South Stack Lighthouse sits on a small sea stack just offshore and is historically important for guiding shipping around the cliffs; it is accessed from the cliff top by a steep stairway and path.
- Cliff-top viewpoints and seabird colony: The cliff-top area and coastal footpaths form a birdwatching and viewpoint zone where seabirds nest on the sea cliffs during the breeding season and where visitors observe coastal geology and sea views.
How to Get to South Stack #
South Stack (off Holyhead, Anglesey) is reached from Holyhead town by a short drive of about 5-10 minutes (roughly 5 km) - follow local roads from the A55 to the South Stack car park/viewpoint. From the car park there is a short but steep walk (with steps) down to the lighthouse viewpoints; allow 15-30 minutes for the walk depending on pace. Holyhead is served by rail and local bus links from Bangor and elsewhere on Anglesey; from Holyhead station a short taxi or local bus will take you to the South Stack visitor area.
Tips for Visiting South Stack #
- Aim for early morning or late afternoon to catch the best light on the cliffs and to avoid mid-day coach crowds that arrive in summer.
- Use the official viewpoint and RSPB paths rather than improvising along the cliff edge; watch for seabird colonies (puffins and gannets in breeding season, May-July) from designated hides or viewpoints that many visitors overlook.
Best Time to Visit South Stack #
Visit South Stack in late spring to early summer for active seabird colonies and generally milder conditions; expect breezy coastal weather year-round.
