Along the edge of the marshlands, over the Old Down ridge, then skirting the historic marshland edge town of Thornbury passing the church and castle. Into the Little Avon valley and round by the north to the Cotswold edge town of Wotton-under-Edge. Thence south along the edge through the villages of Morton, Alderley and Hillesley before descending to cross the north of Inglestone Common with return across the Ladden Vale through Cromhall, to Alveston and back to the Severn Side marshlands.
Generally quiet roads, direct crossings of the A38 in Lower Stone and Alveston, somewhat fast, but low traffic, B4058 section south of Cromhall. The side loop west of Wickwar is more amusingly rural but not necessary for traffic reasons.The route shown is the only way through Wotton-under-Edge from the north, Long Street being one way upwards, unless you walk south from the bottom of Long Street after descending Sim Lane. Roadside snack spots near the Little Avon bridge and in the old Tytherington quarry.
Thornbury Castle and church
Autumn near Horley - the Tyndall monument looks down on stubble
Wotton-under-Edge - the mostly Georgian facades of Long Street
Wortley - not so characteristically Cotswold thatched cottage
Wortley - more classically Cotswold stone houses.
