The Union Canal is a canal in Scotland that goes from the Falkirk Wheel all the way to the centre of Edinburgh. The canal terminates at Edinburgh Quay, less than a kilometre away from Edinburgh Castle. These days the canal itself is only used for leisure activities such narrowboats, rowing, and canoes. But the canal also comes with other benefits, such as a towpath that has been converted to a cycle path, and a microcosm for plants and birds providing a much needed greenspace.
