Always handy to know a bike shop is within the area. Framed bikes is on the main street through Llanberis. The owner said there is a two to three week wait for work, but I got the feeling he would assist riders passing through

Excellent sight looking across Llyn Peris which is 503mtrs above sea level. Dinorwig hydroelectric power station is straight across the lake, this generates 1728MW of power. There are 16 kilometres of deep tunnels in Elidir Mountain. This was opened in 1984

The visitor centre is located on the A5, approximately 5 miles south of Bethesda and approximately 4 miles west of Capel Curig, on the western side of Llyn Ogwen. There are a number of facilities including toilets, disabled toilets, an information room, public wifi and a small kiosk selling hot and cold snacks. From the visitor centre you can start a range of walks and climbs in the area. The most popular is the walk to Wales' first ever national nature reserve, the beautiful Cwm Idwal, a glacial lake with a mountainous backdrop. (Cwm Idwal National Nature Reserve)
