Keston is a suburban part of the London Borough of Bromley. It lies on the edge of Hayes Common.
Its small church is unusual in that does not have a dedication to a saint.
The River Ravensbourne has its source at Keston Ponds. The “London LOOP” walk passes the ponds (where many a small boy caught his first roach, perch &c.) on its way from Farnborough to West Wickham.
Keston village is served by two Transport for London bus links, the 146 Bromley North – Downe; 246 Bromley North – Westerham (Chartwell during the summer).
