1Cardiff
Base · 1–2 nights
Wales’s most useful urban base: arcades, Cardiff Castle, St Fagans, Cardiff Bay and stadium energy all fit into a compact, walkable break. Give it two full days; it is a strong opener, not a reason to skip the coast or mountains.
2Pembrokeshire
Base · 3–5 nights
The coast-first choice: Tenby for restaurants and rail access, St Davids for the wilder western peninsula, and selected Coast Path walks rather than a futile attempt to cover it all. Split bases if you want both Tenby/Bosherston and St Davids/Marloes properly.
Eryri (Snowdonia)
Base · 3 nights
Wales’s defining mountain country, with Yr Wyddfa, slate landscapes, lakes and excellent bases in Llanberis, Beddgelert and Betws-y-Coed. Treat the summit as a weather-dependent mountain day, not an item to force into the schedule.
4Conwy and Llandudno
Base · 2 nights
The best car-free North Wales pairing: Conwy delivers the essential castle and walls, while Llandudno supplies rail links, beds, the promenade and Great Orme. Use it as a base for the coast and eastern approaches to Eryri rather than lingering solely in Conwy.
Bannau Brycheiniog, Brecon, Crickhowell and Hay-on-Wye
Short stop · 1 night
The practical southern mountain alternative to Eryri: ridges, waterfalls, canal country and unusually good small towns. Base around Brecon or Crickhowell for walking; stay in Hay if bookshops and the literary scene matter more than trail access.
Swansea, Mumbles and the Gower Peninsula
Short stop · 1 night
Come for Gower, not for a grand-city experience: Rhossili, Three Cliffs Bay, dunes, coves and cliff paths are the point. It is the easiest serious beach-and-walk escape from Cardiff, though sunny-weekend traffic and parking are punishing.
Anglesey / Ynys Môn
Short stop · 1 night
A flatter, wider-skied North Wales of beaches, seafood, South Stack cliffs and Beaumaris Castle. It works best as a one- or two-night extension from Conwy or Eryri, with a car for anything beyond the main towns.
Cardigan Bay and Ceredigion
Base · 2 nights
A slower west-coast stay built around Aberystwyth, Aberaeron and New Quay rather than headline sights. Choose it for dolphins, promenades, coves and a useful rail base—not for a rapid checklist trip.
Llŷn Peninsula, Portmeirion and the southern Eryri coast
The quieter, more Welsh-speaking side of North Wales: Portmeirion, Harlech, Porthmadog, heritage railways and broad beaches make a convincing second visit. Distances are slow and a car is close to essential.
The Wye Valley and Monmouthshire
Wooded river country for Tintern Abbey, Chepstow and Raglan castles, gardens and country-hotel stays. It is a polished one- or two-night Cardiff add-on, but not the place to seek Wales’s big mountain drama.
Llangollen, Dee Valley and Wrexham
A worthwhile northeast detour for the Pontcysyllte Aqueduct, canal walks and Llangollen’s festival character; Wrexham adds football and a practical transport base. It is best folded into a North Wales or borderlands trip rather than treated as a substitute for Cardiff.
Sample routes
South Wales and Pembrokeshire first trip
7 nightsCardiff (2 nights) → Bannau Brycheiniog, Brecon, Crickhowell and Hay-on-Wye (1 night) → Pembrokeshire (3 nights) → Cardiff (1 night)
The sensible first car trip for travellers who want a capital, proper hill country and Wales’s best coastal walking without wasting days driving to the north. In Pembrokeshire, choose Tenby for convenience or St Davids for the stronger coast-path experience; do not pretend one base covers the whole county.
Plan this routeNorth Wales classic: castle, mountains and island coast
6 nightsConwy and Llandudno (2 nights) → Eryri (Snowdonia) (3 nights) → Anglesey / Ynys Môn (1 night)
The strongest compact North Wales itinerary. Start with Conwy’s castle and Llandudno’s easy rail access, then give Eryri enough time for one weather-flex mountain day rather than forcing Yr Wyddfa. Finish on Anglesey for Beaumaris, Menai Strait and South Stack; a car makes the final two stops far better.
Plan this routeWest Wales coast and culture
10 nightsCardiff (2 nights) → Swansea, Mumbles and the Gower Peninsula (1 night) → Pembrokeshire (5 nights) → Cardigan Bay and Ceredigion (2 nights)
A coast-led route for people who would rather walk cliffs, swim when the weather allows and linger in small towns than chase every headline sight. Use the long Pembrokeshire stay to split between Tenby and St Davids if driving; that is far more workable than repeatedly crossing the county. Aberystwyth or New Quay provides a quieter final change of pace.
