Beddgelert is a lovely village below Moel Hebog, and the bridge over the river is a key feature.

Porthmadog came about after William Madocks (a guess this is where the name of the town derives from) built a sea wall, the Cob to reclaim land from the sea for farming use. The diversion of the river caused it to scour out a new natural harbour deep enough for small ships and the first public wharves appeared in 1825. Quarry companies followed, with wharves along the shore mainly for the transport of slate and due to this the town grew in population and importance.

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.

Presumably there was a bridge here for a long time that gave access from the north side of the river to the Augustinian priory of Beddgelert. In 1623 it was recorded that the bridge needed repairs and in 1778 it was repaired and widened. Much of the bridge appears to have been swept away in a flood of 1799 and was repaired again and doubled in width between 1802 and 1811. (British Listed Buildings)
