[2][3] Beyond this the gorge is part of Chatelherault Country Park, to the south of Hamilton.

Many features of this period remain in the park, including the Duke's Bridge which crosses the gorge.

The river bends to the east at the end of the gorge between the villages of Barncluith and Ferniegair, flowing beneath three listed stone bridges: a viaduct carrying the Argyle Line railway tracks, a single-arch bridge [de] carrying the A72 road, and the Old Avon Bridge [de], now a footbridge.

The Avon Water flows north beneath the M74 motorway, merging into the Clyde between Hamilton and Motherwell, beside Junction 6 of the M74.

The name Avon is derived from the Brittonic *āβonā- (from āβ, "moving water", with the suffix –onā-),[4] the word ancestral to Welsh afon, meaning "a river".
