It's a lengthy piece to quote so I'll link it here https://kentfilmoffice.co.uk/kent-movie-map/james-bond-ian-fleming/
Kent Film Office have a wealth of information on Kentish locations both for the films and books. For me, the key nugget is a map and text detailing Bond's routes in both Moonraker and Goldfinger. More-so Moonraker as that chase from London of Drax and Gala is one of the most thrilling scenes in a Bond novel.
