Rio Avon (Escocia)

This river is technically a tributary of the River Clyde, but it is so big that nobody would say that is a tributary. Its strong current and cold water makes it a good place to fish for salmon. Possibly the most beautiful part is in the park of Chatelharault. This river has a length of about 36 kilometers and was largely controlled by the Dukes of Hamilton, now offering a variety of routes in the area, with free access. Its source is in the hills between East Ayrshire and South Lanarkshire.
