a great castle to explore with views over the se and the Llyn peninsula. It has an informative video that explains its history and then a walk across the bridge that leads you through the fortifications. you can then explore all the rooms that have exhibits of the castles history within them. to finish off you can climb the tower to see the view. Great for kids as there is a park next to it and a cafe across the bridge to keep everyone happy. Parking is available on site but it is a small carpark.

The bridge is dated back as early as the 12 century, and had undergone many facelifts over the centuries. River Glaslyn flows underneath.

Beddgelert is a tremendously picturesque village, nestled beneath the southern end of the Yr Wyddfa (Snowdon) massif at the confluence of the Rivers Glaslyn and Colwyn. Its gorgeous location, charming train line and excellent trails make it a very popular stop off. Yr Wyddfa's quieter southern flanks can be accessed from the village but Beddgelert is more often associated with the Moel Hebog range to the west, where there are some wonderful trails.
