At different stages of this walk the high, slender spire of Lechlade’s majestic parish church is seen on the horizon, even as the route strays into Wiltshire and Oxfordshire. The church was the inspiration for Percy Shelley’s Summer Evening Meditation, which includes these words:

Clothing in hues of heaven thy dim and distant spire

Around whose lessening and invisible height

Gather among the stars the clouds of night

The church has a panelled chancel roof decorated with 40 exquisitely carved bosses and stone corbels. The exterior is parapeted with two rich tiers of quatrefoils. Pinnacled buttresses bear the weight.

On the last leg of the walk there's another interesting church, at Buscot. It contains a striking east window by the pre-Raphaelite artist Edward Burne-Jones, a pulpit partly made from a Flemish triptych, and some delightful paintings.

A riverside town

Lechlade was the upper limit for navigation on the Thames, and is the only town within the county of Gloucestershire to be found on the river. In 1789, when the Thames and Severn Canal was completed, it became possible to move cargoes from ship to barge for the 29-mile (46.5km) journey across Gloucestershire. Cotswold stone for the dome of Wren’s St Paul’s Cathedral was loaded into barges at Lechlade and at one time Gloucestershire cheeses also began their journey to London from here.

With both the River Coln and the River Leach flowing into the River Thames hereabouts, it is no surprise that there are a number of bridges on this walk. Beneath the bridges, crowds of river pleasure craft have replaced the trading vessels of the past while, above, the bridges continue their function, bearing modern-day road traffic. Near the start, the walk crosses Ha’penny Bridge, a late 18th-century toll bridge. The toll house still stands.

St John’s Bridge, the last bridge before Ha’penny Bridge on the walk back to Lechlade, dates from the 14th century and takes its name from a former priory nearby. This, like Ha’penny Bridge, was also a toll crossing. The road was turnpiked in 1725 and the bridge was rebuilt about 1830. Nearby St John’s Lock includes the statue of Father Thames. It was built for the Great Exhibition of 1851, and  moved here from its original site at Thames Head near Cirencester.

From the car park in Lechlade go south to the Market Square, then walk west along the High Street, and then left along Thames Street. Cross Ha’penny Bridge and on the far side drop down some steps on the right to the riverbank. Walk ahead, with the river to your right, for just over 0.5 miles (800m). After passing a bridge across the Thames, draw level with an old roundhouse among the trees on the far bank.

Here the River Coln joins the Thames, alongside the now silted-up Thames and Severn Canal. Continue along the riverbank, cross a footbridge over a stream, and head across the field to find a kissing gate to the left of Inglesham House. The walk continues by turning left along the lane, but to visit Inglesham Church turn right. This charming medieval building, much admired by William Morris, contains an exceptionally beautiful 13th-century stone carving of a Madonna and Child.

At the end of the lane turn right along the main road, using the verge. After 200yds (183m) turn left towards Buscot. In 0.75 miles (1.2km) turn left along the drive of Buscot Wick Farm. Just before the farmyard and cottages turn right along a drive and then go across some grass to a gate.

Look for near and distant black gates across extensive pasture and use them to guide you. Keep to the right of a copse, passing through three gates to reach the road. Go through a gate on the far side, cross two fields to a stile and turn left into the churchyard. Leave by the lychgate and follow the riverbank to emerge at Buscot Weir.

Follow the concrete track here if you want to visit the estate village of Buscot, which now belongs to the National Trust. Otherwise turn left, then right to pass Lock Cottage and make your way across a succession of locks and bridges at Buscot Lock, following a sign for 'Lechlade2 miles (3.2km)'. Continue to a galvanized gate by a large sign indicating the lock ahead. Follow the river’s meanderings, with the spire of Lechlade Church seen in the distance, and remain on the tow path to a wooden bridge just beyond a 3-way post.

Cross this and turn right to continue along the riverbank, noting the River Leach across to your right, which joins the River Thames just before St John’s Bridge. Walk beneath the bridge, pass St John’s Lock, then enter a wide meadow to return to Ha’penny Bridge and Lechlade. Turn right at the High Street and walk back through Lechlade to return to the Memorial Hall car park.
