Welsh Wanderer: Self-Launched 5-Day Wales Road Trip

Start early. Take a Great Western Railway train from London Paddington to Oxford (~1h, £8–15 if booked in advance) or even as far as Moreton-in-Marsh on the Cotswold line (~1h40, £12–20). If you want the classic Cotswold villages (Bourton-on-the-Water, Stow-on-the-Wold), use the Pulhams 801/802 bus from Moreton-in-Marsh (£4–6 day ticket). From Oxford, take a coach to Hereford (National Express/Megabus, £10–18) and continue by TrawsCymru or local bus to Hay-on-Wye (~£4) — the book-town stop from the original itinerary. A short local bus runs from Hay to Brecon (£3–5); if you have time, a taxi-share or the X43 bus from Brecon to Merthyr then the T4 onward is possible, but the simplest is to continue up the A470 by coach. From Brecon, the TrawsCymru T4 route (which runs the beautiful Elan Valley/Cambrian Mountains corridor) or the T1 to Aberystwyth takes roughly 2–3 hours (£6–10). Arrive Aberystwyth evenings: walk the promenade, see the castle ruins and Constitution Hill, and eat at a seafront pub (£10–14).

🚌GWR train London–Oxford/Moreton-on-Marsh (£8–20), coach Oxford–Hereford (£10–18), local bus to Hay-on-Wye (£4) and onward TrawsCymru T4/T1 to Aberystwyth (£6–10). Total roughly £30–45.

🛏Budget B&B or hostel in Aberystwyth, e.g. a private room in a guesthouse on the seafront (~£45–60 a night shared, £25–30 pp)

• →Walk the Cotswold villages around Moreton-in-Marsh or Stow
• →Browse the bookshops of Hay-on-Wye
• →Brecon Beacons / Elan Valley scenery from the coach
• →Aberystwyth promenade and castle ruins

Take the scenic Cambrian Coast line: Transport for Wales train from Aberystwyth to Barmouth or Harlech (~1h30–2h, £10–14). The line hugs Cardigan Bay with estuary views — arguably better than the minibus drive. From Harlech, walk up to Harlech Castle (Cadw ticket £7.50; book on the Cadw site or just turn up) for the classic Snowdonia panorama. Then take the TrawsCymru T2 or T3 bus (Snowdonia network, ~£5–8) to Beddgelert — a stone village at the foot of Snowdon with the Gelert's Grave legend walk. If you want a proper hike, the Beddgelert circular (2–3 hours) or the Rhyd Ddu path up Snowdon is possible with an early start; the Snowdon Sherpa bus network (S1–S5, £5 day ticket) makes the mountain accessible without a car. Return to Aberystwyth in the evening by train via Barmouth, or if you prefer less backtracking, overnight in Harlech/Beddgelert and adjust Day 3.

🚌Aberystwyth–Harlech train (£10–14), Snowdon Sherpa/TrawsCymru buses (£5–8 day ticket), return train (£10–14). Total roughly £25–36.

🛏Return to Aberystwyth guesthouse, or a night in a Harlech/Beddgelert B&B or hostel (~£25–35 pp shared)

• →Cambrian Coast railway (request a window seat)
• →Harlech Castle (~£7.50)
• →Beddgelert village and Gelert's Grave walk
• →Optional low-level Snowdonia hike

A long but rewarding travel day. Take the TrawsCymru T1 or T5 bus down the Cardigan Bay coast with a stop in New Quay (dolphin-watching from the pier is free; boat trips £15–25 if you fancy it) and Aberaeron's pastel harbour. Buses run roughly hourly in summer, less often out of season — check Traveline Cymru the night before. From Carmarthen, catch a local bus to Laugharne (the Dylan Thomas boathouse and castle, free to walk) and then continue to Tenby. Dinefwr Estate (National Trust, ~£8–10) or Carreg Cennen Castle (~£6) are easiest reached by taxi from Llandeilo or Carmarthen (£10–15 each way) — skip if timing is tight. Arrive Tenby in the evening: pastel harbour, town walls, and a pint at a harbour pub (£10–14 for dinner).

🚌TrawsCymru and local buses Aberystwyth–New Quay–Aberaeron–Carmarthen–Tenby (£12–18 total with a day/rover ticket), optional taxi to Dinefwr (£10–15 shared). Total roughly £20–30.

🛏Tenby hostel or B&B near the town centre (~£50–65 a night shared, £28–35 pp)

• →New Quay harbour and dolphin spotting
• →Aberaeron harbour stroll
• →Laugharne castle and Dylan Thomas boathouse
• →Optional Dinefwr or Carreg Cennen Castle
• →Tenby town walls and harbour at dusk

Take the Pembrokeshire Coast Path (free) from Tenby toward Manorbier or Saundersfoot for a 2–3 hour clifftop walk — no guide needed, waymarking is excellent. In the afternoon, take the Taf Valley Coaches 349/351 or the coastal bus (Pembrokeshire Greenways, ~£5–7 day ticket) to Pembroke to walk the medieval walls and see Pembroke Castle (£7.50). Alternatively head west on the T11/T5 to St Davids — Britain's smallest city — for the cathedral (free entry, donation appreciated) and a coastal walk to St Non's Bay. The original tour does St Davids plus Pembroke in one day by minibus; independently, choose one and do it well. Return to Tenby in the evening.

🚌Pembrokeshire coastal/Greenways buses day ticket (£5–7), plus local buses (£3–5). Total roughly £10–15.

🛏Second night in Tenby hostel/B&B (~£28–35 pp)

• →Pembrokeshire Coast Path clifftop walk
• →Pembroke Castle (~£7.50) or St Davids Cathedral
• →St Non's Bay coastal walk
• →Harbour lunch in Tenby or St Davids (~£10)

Train from Tenby to Cardiff Central (Transport for Wales, ~2h, £12–18 if booked ahead). From Cardiff, bus 32/32A or a 20-minute train to Waun-gron Park plus a short walk takes you to St Fagans National Museum of History — free entry, open-air museum with original Welsh buildings, and easily 2–3 hours. If you want the Cotswold-style village finale, an alternative is to route home via Bath or Castle Combe: train Cardiff–Bath Spa (£10–15) then bus 35 to Castle Combe, before continuing to London Paddington (£30–45 advance). Most travellers will simply take the direct Cardiff–London train (~2h, £25–45 booked in advance) and be back by early evening. This is the DIY version of the last day — you skip the guided Severn Crossing commentary but save the private transfer cost.

🚌Tenby–Cardiff train (£12–18), local bus to St Fagans (£2–3), Cardiff–London train (£25–45 advance). Total roughly £40–65.

🛏Not included — onward travel or London hostel (~£25–35 pp if needed)

• →St Fagans National Museum of History (free)
• →Cardiff city centre and castle grounds
• →Optional detour via Bath/Castle Combe
