Caerphilly
Caerffili
One night is enough: castle in the morning, then Cardiff or the mountain. Skip as a base unless you have a car.
Caerphilly is a small town 15 minutes by train from Cardiff, built around the biggest castle in Wales and a moat with leaning towers. The castle and the town centre fill half a day; the rest of the trip is Cardiff, Castell Coch or walks on Caerphilly Mountain. Most travellers come as a day trip and sleep in Cardiff, where the choice of beds is far wider.

Etiquette, safety and scams
Etiquette
- Greeting: Handshake at first meeting; 'hi' and first names quickly; avoid: Cheek kisses with strangers
- Conversation: Weather is a safe opener; understatement and self-deprecating humour; avoid: Asking about salary or class
- Queues: Join at the back; avoid: Pushing onto buses or trains before others get off
- Apologies: 'Sorry' is said constantly, even when not at fault; avoid: Taking it as an admission of blame
- Pubs: Buy rounds in a group; wait at the bar without waving money; avoid: Clicking fingers at staff
- Nations: Call Scots Scottish and Welsh Welsh; avoid: Calling the whole UK 'England'
Scams and watch-outs
- Castle opening hours shorten in winter and Sunday opening starts later: check Cadw before you travel.
- The Big Cheese festival (last weekend of July) fills the town: book beds and expect road closures.
- Rural lanes around Caerphilly Mountain are narrow and unlit: don't walk them after dark.
A quiet town and one of the safer parts of South Wales. The real risks are wet pavements, unlit lanes on the mountain and the usual weekend pub crowd in the centre.
