The River Avon flows from its sources near Sherston and Tetbury to its confluence with the Severn at Avonmouth some 117 kilometers and is fed by many tributaries on its way.

The headwaters of the River Avon, the Tetbury and Sherston branches join at Malmesbury. Both are important Trout streams where fishing is strictly preserved, and there is little opportunity for the visiting angler to fish these waters.  

However, we have enumerated a number of free fishing spots here, including the Bristol Channel.
