The spring from which the Chew rises is just upstream from Chewton Mendip. The river flows North West from Chewton Mendip through Litton, Chew Valley Lake, Chew Stoke, Chew Magna and Stanton Drew. The river passes under the A37 at Pensford and then flows through the villages of Publow, Woollard, Compton Dando and Chewton Keynsham before joining the River Avon at Keynsham. For much of the Chew's route the Two Rivers Way footpath is alongside, the same route for part of its length is also part of the Monarch's Way long distance footpath. In total the Chew flows for some 17 miles through the North Somerset countryside.
