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)

Outside the former church stands the Capel Curig War Memorial, in the form of a Celtic cross, commemorating six soldiers who died in the First World War. The names of residents who served in the First World War and returned home are engraved on the sides of the plinth. The names of two men who died in the Second World War were added later to the plinth of the war memorial.

From this point along the path is a beautiful view of the magnificent Marchlyn Bach. This is also a great access point to many great trails where you can discover some of the breathtaking peaks of Parc Cenedlaethol Eryri.

This is campsite in a stunning location with friendly owners. The main advantage of the site is that it is located in the stunning Ogwen valley with great access to the surrounding iconic mountains. Stayed here many a time, and will be staying here in the future too.
