Nice easy flat ride. Can be busy with walkers and other cyclists, particularly on weekends. Early mornings are the best, with so much birdsong and wildlife. Take a moment to enjoy the view of the Weir, which usually has a row of gulls fishing on it.

Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle
