There are a few close together in Coalbrookdale, just above Ironbridge. If you park at GC14B4M and then go along the Rope Walk to GCHJMN. It's a shame that you're not going to see the wild orchids, the wild garlic and the bluebells just yet. On your return journey to the car, go down into Loamhole Dingle GC123X0 (but take a plastic bag or something with you). Follow the path down through the dingle back round to your car.
GC1855W is a nice little walk.
Also, just a very short drive from Coalbrookdale, go up "Jiggers Bank" towards Horsehay. GC1490A is very close to where we live and there's a good fish and chip shop called The Codfather but they're only open til 8pm on a Saturday.
GC16FT3 (A Blist from the Past) is also worth a look, and is quite close to GC14WA0.
There are quite a few more in Ironbridge and Coalbrookdale itself worth doing that are not mentioned eg you could join GC16B0W and GC1C21Z in a circular walk from Ironbridge (but make sure you have an OS map so you can be sure you don't head off in the wrong direction and can get back to your car). Don't forget to look back to get excellent views.
