Warning: Diversion in place. Part of this route is closed or diverted for now. The Wales Coast Path site (updated 22 September 2026) lists temporary diversions in several places, many until further notice, including landslides at Porthdinllaen in Gwynedd and Porth Swtan, Llanfaethlu and Lligwy on Anglesey. Neath Port Talbot Council says the path around Baglan, Briton Ferry and Sandfields West has been closed since 2023 because of sinkholes and the agreed diversion stays in place. Check the official diversions page before setting out. Source: walescoastpath.gov.uk.
