Another of Edward I's main castles, where Edward II was born.
Caernarfon Castle is a medieval fortress in Gwynedd, north-west Wales. The first fortification on the site was a motte-and-bailey castle built in the late 11th century, which King Edward I of England began to replace with the current stone structure in 1283. The castle and town established by Edward acted as the administrative centre of north Wales, and as a result the defences were built on a grand scale. There was a deliberate link with Caernarfon's Roman past—nearby is the Roman fort of Segontium—and the castle's walls are reminiscent of the Walls of Constantinople.

Departs from Llanberis. This spectacular 4 mile, roughly 2½-hour train journey climbs 3500 feet up Mount Snowdon and is the only rack-and-pinion railway in the UK, dating to 1896. Trains depart first at about 9AM. There is a 30-minute stop at the summit; the train leaves again promptly, so make sure you are back on time! It costs £60 for a roundtrip, discounted if the first train of the day is taken, or if you go one way. Open mid-March to October, several trains a day, more in summer.
