Traffic-free and almost level from Edinburgh to Glasgow, this route follows the Union and Forth & Clyde towpaths. The Union Canal has no locks, therefore no climbing; the F&C has a few, but nothing to trouble the legs apart from the Maryhill Flight in Glasgow. The two canals are joined by the spectacular Falkirk Wheel boat lift. Sights along the way include the Union's aqueducts and the F&C's floating fish and chip shop! Outside urban areas, the surface is mostly unpaved but in good, firm condition.
