The Greensand Ridge Walk is a long-distance walk of 40 miles (64 km) that traverses the county of Bedfordshire in England, with brief sections in the neighbouring counties of Cambridgeshire and Buckinghamshire. Its southern endpoint is at Leighton Buzzard and the route runs north-east to finish at Gamlingay. As can be inferred from the name, the walk follows the Bedfordshire Greensand Ridge (not to be confused with the Greensand Way, the greensand ridge that can be found in Surrey, Sussex and Kent).
