A hidden, deep-sided valley between Marlow and Henley-on-Thames, with curiously-named and pretty chocolate-box villages Hambleden, Skirmett (with its pub called "The Frog" - geddit?), Fingest, Frieth, Turville and Turville Heath. The Vicar of Dibley, Chitty-Chitty Bang-Bang, and many other British classics, have been filmed in these villages and the nearby countryside.
