Approach notes

Access to especially the Main Cliff and Easter Island is affected by the tides. Climbers visiting these areas are advised to check the local tide tables, which may be purchased in Holyhead.

Approach for South Stack, Upper Tier and Main Cliff areas: Turn left off the A5 at the Valley traffic lights, three miles from Holyhead, and follow the B4545 to Trearddur Bay. Turn left again at GR255793 where a twisting coastal road leads past several small coves to another left turn after three miles; a narrow road runs up to the South Stack Cafe. The South Stack cliffs lie just below the cafe and car parks. For Upper Tier and the Main Cliff an path leads north east from the upper car park past a prominent telecoms relay station towards the south-facing crags on Holyhead Mountain. The path now splits, where the right path continues over the mountain to North Stack, whilst the left path drops down to a well-worn site at the top of the descent gully, overlooking Gogarth Bay. From the foot of the gully a path contours round the hillside below the Upper Tier. Just around the corner beyond the prominent pinnacle (Shag Rock) a branch of the path drops steeply down to Main Cliff.

For North Stack Wall and Wen Zawn, on entering Holyhead, follow Victoria Road (A5) to the harbour. Turn left along the Prince of Wales Road along the harbour front, and continue along a minor road forkig left where the main road bears right. Follow this deteriorating 'road' until you reach the parking areas near the Holyhead Quarries (GR225834). Follow the path climbing steeply up the hillside, taking the left fork when it divides after half a mile. Continue uphill until the path divides again. The right path runs down by some telegraph poles to the North Stack fog-warning station, and the left leads up to a col just above Wen Zawn.
