Frome Valley Walkway

The Frome Valley Walkway is an 18-mile footpath which follows the River Frome from the River Avon in the centre of Bristol to the Cotswold Hills in South Gloucestershire. The path also links the Cotswold Way National Trail at one end with the Avon Walkway at the other.

Starting in Bristol's Castle Park, the path skirts public parks in the city, where the river is culverted, and only becomes rural as it passes through Eastville Park. The walk then continues past Snuff Mills and on to the Oldbury Court Estate, passing beneath Frenchay Common, then to Cleeve Bridge before passing under the M4 motorway at Hambrook. Next, the path passes through Winterbourne Down, and under the Winterbourne Viaduct.
