A word of warning. The walk descriptions are not detailed enough to guide you - please take a map. The batteries never run out, and you always have a signal. Oh, And don't take left or right as gospel!
While travelling over to Wales, we stopped at Sycharth Castle, near Oswestry - a green mound with a view that was once the home of Owain Glyndwr. Very steep, but short, and a pleasant place for lunch.
