Gloucestershire
The House of the Tailor of Gloucester (Gloucester) - Beatrix Potter sketched this house for The Tailor of Gloucester. The house is absolutely charming, and you'll feel like you've stepped into in the story.
Gloucester Cathedral (Gloucester) - Gloucester Cathedral is Gothic architecture at its best and avid Harry Potter fans will recognize many exteriors from the movie (students of the King's School next door were extras.) Don't miss a photographic exhibit which shows how the cloisters were transformed for the film.
The Royal Forest of Dean - The Forest of Dean was a royal hunting preserve in Norman times and today, the forested hills and river valleys are still incredibly peaceful.
Wander through the Puzzle Wood near Coleford, or ride on a steam train, the Dean Forest Railway (Lydney) or the Perrygrove Railway (Coleford).
Cruise down the serene Symonds Yat River in the lazy summer afternoon.
On a more industrial note, explore Clearwell Caves, natural caverns mined for iron ore since the Roman era.
