The most well-preserved concentric castle in Britain and can be seen from the national park.
Beaumaris Castle, in Beaumaris, Anglesey, Wales, was built as part of Edward I's campaign to conquer north Wales after 1282. Plans were probably first made to construct the castle in 1284, but this was delayed due to lack of funds and work only began in 1295 following the Madog ap Llywelyn uprising. A substantial workforce was employed in the initial years under the direction of James of St George. Edward's invasion of Scotland soon diverted funding from the project, however, and work stopped, only recommencing after an invasion scare in 1306. When work finally ceased around 1330 a total of £15,000 had been spent, a huge sum for the period, but the castle remained incomplete.

Provide mountain guiding in Snowdonia and training courses in navigation, scrambling and rock climbing.
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. Be prepared to wait several hours after buying your ticket.
