Late spring (May–June) and early autumn (September–October) offer the best combination of pleasant weather, fewer crowds, and accessible attractions. April and early May are lovely if you're prepared for Welsh rain. Summer holidays (July–August) are warmer but busier, especially near castles and beaches.

Yes, several sites offer dedicated motorhome pitches, including commercial caravan parks and council-run facilities. The town of Llandeilo offers seasonal motorhome parking with services. Many larger car parks at attractions (Dinefwr, Kidwelly) accommodate motorhomes well. Always book ahead during school holidays and peak season.

Wild camping (free overnight parking) is discouraged in town centres and on public highways. However, several quiet lay-bys, farm pitches, and rural car parks allow short-term motorhome stops. Always seek permission on private land and respect local guidelines. Apps like iKamper and Parkopedia list legal stopping spots.

Carmarthen town centre has height restrictions and narrow streets unsuitable for large motorhomes. Park at the outer car parks (Spilman Street or Lammas Street car parks have generous spaces) and walk the short distance into town. The Tesco supermarket on the outskirts is more accessible and has motorhome-friendly parking.

Welsh weather is changeable—bring waterproofs, layers, and sturdy walking boots for exploring castles and countryside. A good sat nav with motorhome height/width settings is essential. Fill fresh water and waste tanks before leaving larger towns. Take a camping stove or barbecue for scenic picnic stops, and download offline maps in case of poor signal in rural valleys.

The Towy Valley scenic route from Llandeilo to Dinefwr is beautiful and motorhome-friendly. The A48 connects major towns efficiently. For scenic drives, try the quiet roads between Laugharne and Pendine, or loop through the Black Mountain foothills. Avoid narrow lanes in hill villages and use Sat Nav with motorhome settings to prevent height restriction surprises.
