As part of the LDWA 50th celebrations, we have devised a year-long challenge for all our walkers: the Essex & Herts I Spy 50 for 50.

This is a list of 50 things that you might hope to see while walking in Essex or Hertfordshire are listed - ready for you to tick off once you have spotted them.  The only rule is that you must have seen them while walking on an Essex & Herts Social or Challenge Walk.  Some easy, some a bit harder, and hopefully varied enough to continue throughout our Birthday year.  So here is your list - print it off, pop it in your rucksack or pocket (or for the more techno-minded, save it on your phone), then just keep looking for what you can spy.
