Lugging a book around is a bit of a pain when you go out walking. I've used the 'city walks' cards in the past and found them great, so when I saw these cards with circular country walks close to London I bought them immediately. They're really nicely presented and the plastic wallet to keep rain of the card is a nice touch. The first walk I tried went without a hitch and was really enjoyable. However my next attempt was a disaster (Walk 27) . It wasn't clear which path to take from the car park. We tried 3 different ones then gave up. The lack of space on the cards means that useful detail is lacking. The directions on our third walk were even vaguer (Walk 23). We got completely lost twice and only found our way back to the car with the aid of the maps on my iphone.
It such a shame because if the directions were clearer I'd recommend them.
