The Clyde Walkway DOES Not extend the whole way from Glasgow to Hamilton. There is 4 mile/6 Km gap between the old Railway Bridge at Carmyle and Uddingston.
There are no sign posts or paths to follow. In fact, I would say it is the most dangerous part of the entire walkway due to swamp and a bracken Jungle,

However, I completed the part from Glasgow to Uddingston 2 weeks ago and kind of surveyed this part of the Walkway.

This will give an idea of what to expect on this part of the route, Happy Walking
