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.

This Weir is a wonderful home for birds as they wash their feet, and gossip about others' nests
