Dates are flexible. This day-by-day plan is provisional until you choose exact travel dates.
Start with an easy orientation along Aberystwyth Promenade, allowing about an hour to take in the Victorian seafront, shingle beaches, and wide views across Cardigan Bay. Keep the windbreaker or waterproof jacket handy—the promenade can feel brisk even in May—and watch for wet patches and spray near the water. From the southern end, walk a few minutes inland to Aberystwyth Castle, where the atmospheric ruins and grassy grounds make a good contrast to the polished seafront; allow another hour. Entry to the ruins is generally free, though opening arrangements and access can vary, and some uneven stonework makes sturdy shoes worthwhile.
Continue into the town centre for Ceredigion Museum, a compact, worthwhile stop for local maritime history, everyday Welsh life, and regional art. Set aside about an hour, but check its current opening days and hours before setting out, as seasonal schedules can change. It is an easy walk from the castle—roughly 10 minutes through central streets—and cafés around Great Darkgate Street are convenient if you want tea before dinner. For a relaxed evening meal, book or arrive early at The Angel, where Welsh-influenced dishes and good drinks make a fitting introduction to the area; budget approximately £20–35 per person, and allow around 1½ hours.
After dinner, return toward the water for Aberystwyth Pier and a final 45-minute stroll. The pier is particularly enjoyable as the light softens over Cardigan Bay, with the promenade giving you room to wander without committing to another long walk. Check sunset time on the day and bring a warm layer; the exposed pier is noticeably colder than the town centre. If conditions turn wet, the pier’s sheltered sections and nearby seafront cafés provide an easy fallback, and the central hotels and railway station are all within a short walk.
Begin in North Aberystwyth and allow roughly two hours for the return walk up Constitution Hill. From the town centre, follow the seafront north and pick up the signed hill path; it is a steady climb rather than a technical hike, but the exposed summit can be muddy and very windy in May. Wear your waterproof boots, bring a mid-layer and rain jacket, and carry water. At the top, pause for the wide views over Cardigan Bay, with binoculars useful on a clear day. The walk itself is free, though the path can become slippery after rain.
Descend using the Aberystwyth Cliff Railway if it is operating. Allow 20–30 minutes including a possible wait, and check the seasonal timetable before setting off, as operating days and hours vary outside the main summer period; a small fare applies. If it is closed, return on foot via the hill path. Continue down to North Beach for about 45 minutes beside the shore—this is a good place to let the legs recover, but keep your windbreaker close and avoid the waterline in rough weather. Then walk south along the seafront to Aberystwyth University Old College, allowing around 45 minutes to admire its Gothic exterior. Interior access is dependent on events, tours and building operations, so treat the outside architecture as the reliable visit rather than planning around entry.
Finish at Pysgoty in the town centre for coffee, cake or a light lunch, usually around £8–15 per person. From Old College, it is an easy walk inland through the centre; allow extra time if the café is busy at lunchtime. After eating, leave the rest of the afternoon unstructured for a relaxed wander through the central streets or a return to your accommodation—your boots and waterproofs will likely appreciate a chance to dry after the hill.
Take a morning Transport for Wales Cambrian Coast Line train from Aberystwyth to Borth, allowing 15–20 minutes on the train plus time to reach the station and check the return timetable. An early departure is best—ideally around 8:00–9:00am—as services are limited. A single fare is usually around £4–8, but check current times and prices before setting out. From Borth station, it is only a short walk to Borth Beach, where you can spend about 1½ hours strolling the broad shore and seafront. This is a good place for binoculars, especially on a clear day, though keep your waterproof layer accessible: the beach is exposed and the wind can change quickly.
Continue inland to Borth Bog, an unusual coastal wetland reached on foot from the village. Allow about an hour for the marked paths and boardwalks; after rain, sections can be soft, so wear the waterproof hiking boots rather than sneakers. Stay on the signed route and avoid straying onto sensitive wetland habitat. There is little shelter or refreshment provision here, so carry water and a snack from Borth.
From Borth Bog, continue north to Ynys Las National Nature Reserve. This is the longest and most open part of the day, with two to three hours for the dunes, saltmarsh, and estuary views. Pack lunch or extra snacks, sunscreen, and a windproof layer; shelter is limited, and the combination of sea glare and wind can be surprisingly tiring in May. Watch for waders and other estuary birds, and check reserve signage locally for any temporary path closures or tide-related restrictions. Allow enough time to return comfortably to Borth rather than relying on a rushed final connection.
Finish with a relaxed meal at The Railway Inn in Borth, budgeting roughly £15–25 per person. Confirm the kitchen and service times before committing, particularly outside the busiest season, and check the evening train back to Aberystwyth before ordering—missing it could mean a long wait, as services are infrequent. The pub is conveniently placed for the station, so leave a modest buffer after dinner for the walk and boarding.
Leave Aberystwyth early—around 8:00am if possible—for the connecting bus services to New Quay. Allow 1.5–2 hours door to door, including the connection in Aberystwyth; services can be infrequent, so check Traveline Cymru the night before and save the return departures offline. On arrival, begin at New Quay Harbour, where the compact waterfront is easy to explore on foot. Spend about an hour looking across Cardigan Bay for dolphins, particularly in calmer weather, though sightings are never guaranteed. The harbour area is exposed, so bring binoculars, a windproof layer and sunscreen even if the morning feels cool.
Walk from the harbour to New Quay Beach, following the waterfront and allowing roughly an hour for the sandy cove and coastal edge. For lunch, settle at The Lime Crab near the harbour—an informal choice for seafood and other easy-going dishes, usually around £15–30 per person. Check its seasonal opening hours before setting out, as coastal businesses can vary their schedule outside peak summer. After lunch, put on your waterproof hiking boots and take the Ceredigion Coast Path toward Cwm Soden for a scenic two-hour out-and-back section. Keep well back from the cliff edges in strong winds, and turn around early if the surface becomes slick; the views are the reward, so there is no need to treat this as a distance challenge.
Return to New Quay with enough time to reach the bus stop comfortably rather than relying on the last possible connection. The journey back to Aberystwyth again involves a connection and can take 1.5–2 hours, so confirm the final practical departure before lunch and keep a power bank handy. If the weather has shortened the walk, use the extra time for a relaxed harbour-side drink—but do not risk missing the return service, as evening alternatives are limited.
