Tips from the Community

Dominiek Van Dooren
May 7, 2026, Pont Aberglaslyn

The bridge was probably built in the 17th century and then radically rebuilt and widened in 1795-1796. As with many older bridges, folk tales claimed that the bridge was built by the devil or by the Romans (which an investigation by the National Trust described as "very doubtful"). During the reconstruction, a stone was found with the inscription "W M 1656" scratched on it, suggesting that the bridge is at least that old. Pont Aberglaslyn is located near the downstream end of the Aberglaslyn Pass. Although the location is rocky and the river flows through rapids upstream, it is not far above sea level. (Wikipedia)

From the Castle you have some very nice views on Criccieth town.

Porthmadog is simply a busy hub, a gateway to the Llyn Peninsula and Snowdonia National Park. It is a lovely harbour town with a gorgeous mountain backdrop. It also has a good range of shops and attractions including nearby Portmeirion, a narrow-gauge railway, a normal railway and guess what...an excellent hands-on railway museum!

Criccieth Castle overlooks Tremadog Bay on the Llŷn Peninsula in North Wales. It was built in the 13th century and remains in remarkably good condition. It's well worth looking inside, although there is a charge, and you can learn about its history from boards. As you might expect, it's blessed with absolutely fantastic views.

Porthmadog is a coastal town in Gwynedd (Wales). It is located 8 km east of Criccieth, 18 km south-west of Blaenau Ffestiniog, 40 km north of Dolgellau and 32 km south of Caernarfon. The population of 4,185 at the 2011 census was estimated at 4,134 in 2019. The town grew in the 19th century as a port for local slate. As this trade declined it became a shopping and tourist centre, close to the Snowdonia National Park and the Ffestiniog railway. It is now a busy port town with a good range of shops and attractions, including nearby Portmeirion. (Wikipedia)
