Lechlade is a town at the edge of the Cotswolds in Gloucestershire, England, 55 miles (89 km) south of Birmingham and 68 miles (109 km) west of London. It is the highest point at which the River Thames is navigable, although there is a right of navigation that continues south-west into Cricklade, in the neighbouring county of Wiltshire. The town is named after the River Leach that joins the Thames near The Trout Inn and St. John's Bridge.
