Aberystwyth to Ynyslas: The Coast Path Walk
The Wales Coast Path runs north from Aberystwyth along the clifftops to Clarach Bay, then down to the beach at Borth and on to Ynyslas at the mouth of the Dyfi estuary. The full distance from Aberystwyth to Ynyslas is around 11.7 miles (18.7 km) — a substantial day walk involving climbs, exposed cliff sections and varied terrain. Most walkers either do it in sections or take the train to Borth and walk back.
The Route
Aberystwyth to Constitution Hill: The walk begins at the northern end of the promenade. Either take the Cliff Railway to the summit (easier) or follow the footpath up alongside the track (steep, around 30 minutes). From the summit of Constitution Hill the coast path continues north — the views here are the best of the entire route.
Constitution Hill to Clarach Bay: About 2 miles of cliff-top path descending to the small sandy cove at Clarach. The path is uneven in places and exposed on the higher sections — use appropriate footwear. Clarach has a small café and seasonal facilities. This section is the most popular single segment of the route and manageable as a half-day walk from Aberystwyth (with the Cliff Railway to the summit and a road walk or bus back from Clarach).
Clarach to Borth: The coast path continues north from Clarach on lower ground towards the long beach at Borth. This section is less dramatic than the cliff walk from Constitution Hill but includes good estuary and dune views as you approach Borth village. The full Clarach-to-Borth section adds another 3–4 miles.
Borth to Ynyslas: From Borth village the route continues along the beach or dune edge north to Ynyslas — around 2.5 miles of open, exposed walking at the end of the Borth beach. Ynyslas is a National Nature Reserve at the mouth of the Dyfi estuary with dunes, shore birds and broad estuary views.
Practical Notes
Distance: Aberystwyth to Ynyslas is around 11.7 miles / 18.7 km. Aberystwyth to Clarach only is around 3–4 miles. Aberystwyth to Borth is around 8 miles.
Return from Borth: The practical return from Borth to Aberystwyth is by train — around 20 minutes on the Cambrian Line. Check timetables before you set out; services are not frequent and the last train of the day should not be missed. Ynyslas itself has no train station: you return from Borth. If you intend to walk to Ynyslas and back to Borth for the train, allow enough time.
Terrain and weather: The cliff-top sections between Constitution Hill and Clarach are steep and exposed. The beach sections near Borth and Ynyslas are flat but can be heavy going in sand at low tide. The coast is exposed to Atlantic weather — check the forecast before a full-day walk, and bring waterproofs regardless.
Footwear: Waterproof walking boots or trail shoes for the cliff sections. Trainers are manageable for the beach sections in dry weather but uncomfortable on the rough cliff paths.
Shorter alternatives: The Cliff Railway to Constitution Hill and back (with or without the café and camera obscura at the top) is a self-contained half-hour to an hour. The walk to Clarach and back is a good 2–3 hour walk. Both are satisfying without committing to the full Ynyslas route.
What to See Along the Way
Constitution Hill summit: 26 Welsh mountain peaks visible on a clear day, Cardigan Bay from the Llŷn Peninsula to Strumble Head, and Ireland in good conditions. Camera obscura at the top.
Clarach Bay: a quiet sandy cove, dog-friendly year-round, with a caravan site and seasonal café. Very different in character from the town beaches.
Borth beach: one of the longest beaches in Ceredigion, dog-friendly year-round. At low spring tides the submerged forest — blackened tree stumps from a forest that stood here thousands of years ago — is sometimes visible along the shoreline.
Ynyslas: dunes, estuary birds (oystercatcher, dunlin, curlew), views across the Dyfi to Aberdyfi. NNR visitor centre and car park. See the Borth and Ynyslas guide for more detail.
