The road down Steephill is closed at the bottom and there is no way through. Only go down if you want a very challenging climb back up!

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)

Great fun for the kids. Can be cold at times but not very long so you're soon out into the sun.

Great few hours spent. Fairly easy hike.

Nothing especially tricky or difficult, as long as you have vaguely "gravel" tyres you'll be fine. Stunning views along the way, I prefer the heading west views but it is pretty both ways.

This is a serene lake located in the Conwy Valley surrounded by forested hills and the rugged landscape of Snowdonia. There's a cafe and fishery further south along the lake which is a lovely place to stop and refuel.
