This expansive forest is a treasure trove of walking and cycling trails, photographic opportunities and wildlife in the heart of Eryri National Park (Snowdonia). You can enjoy breathtaking views of Yr Wyddfa (Snowdon), picnic by the secluded lake Llyn Llywelyn and listen to the sound of the trains from the Old Welsh Highland Railway, which run through the forest on their way from Caernarfon to Porthmadog. You can also go horse riding. (National Resources Wales)

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)

The path along the lake is very nice. Part of it is actually a kind of dam you walk on, with a barrier on both sides so you have to stay on the path. Because the dam is elevated, you have a good view of the lake and the surroundings.
