Jimmy's ideas OK but some mileage involved. Long Mynd is well worth a look whatever and as you come down go via Carding Mill Valley. Amazing views. Nearby Ludlow is world renowned for its market and for it's butchers (Top 3 in the UK)and restaurants. Shrewsbury itself is well worth a thorough look - beautiful old buildings, castle, oodles of small shops and cafes, snickets with odd names and guided walks, Severn Theatre - and a must is a look into the library which was Darwins (Origin of the species bloke) school. Go to the top floor and have a look at the boys common room and see the graffiti etched into the school benches by the little wotzits 200 years ago and the fabulous ceiling decor of another age. An absolutely gorgeous restoration. If/when you are in Shrewsbury itself and want elevensies or a midday snack, go to the Gallery Tearoom - extremely nice place with a large regular (geriatric?) clientele admiring the dishy girls who serve and very, very reasonably priced (cheap in my opinion) with a coffee top-up thrown in and the best scones in town (my honey on sale too!!). Ironbridge is near-ish with Telfords bridge and the best Indonesian restaurant in the area. Pity you didn't pick the following weekend and go to the Shrewsbury Flower show, masses of stuff to look at including bee stuff and wine. 80,000 visitors over the two days last year.
Otherwise, have a look on the Tourist Office website and if you are a NT member there is another load of things to look at.
Last, at Attingham Park (NT) there is a listed beehouse containing some skeps with bee occupants placed there by my local association. The NT peaple can be a bit difficult over it but persevere. Oh, and one more thing, don't tell too many people how nice it is around here as we try to keep it secret.
Any good?
