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.

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.

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.
