But the Cardingmill Valley, near Church Stretton, Shropshire, is a fantastic place to walk in any weather.
Mist shrouded the hilltops but this is walk is so popular that the car park was more than half full.
The well-defined path makes it easy to get to the head of the valley, (route finding is less easy on the summit).
We take the left fork off the main path, keeping right by the stream (the main path takes the right fork).
After some clambering, the first waterfall
...and a little further on, the second, bigger one
The mist closed in, so we turned back. A full blog of this walk will be done when I can actually post some of the excellent views.
But as a bad weather walk, it was an exhilarating three miles - highly recommended.
Notes: people from the Black Country love this area. There's a National Trust Car Park at the entrance to the valley, and there are easy walks up the valley, with more challenging walks over the Long Mynd. Plus, the stream is fantastic for all ages, for paddling and making dams.
I have to say I have never been in bad weather before and I really have missed out.
PS Also a cafe part way up the valley, heated by a log burning stove and selling breakfast sandwiches till 12.00 (just saying!)
