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.

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.
