The Hatley Heart Attack is a loop of 400+ caches starting in Hatley and heading north east up to Toft before heading south, then south west all the way over to Biggleswade before heading back up to Hatley.
Most tracks are easy walking with a little road walking sometimes needed. There are numerous link caches to break the walk into smaller more manageable chunks. But can you walk the outer ring in one go?
Notes on Puzzles
Please check out the puzzles in advance. They are all easy to solve in advance and lead to a find with a very short diversion from the main route shortly after they appear on the walk.
In a few caches there are clue cards. You will need all the clues to find the final cache in the series
There was very little livestock encountered on route and any caches near livestock will be flagged up on the appropriate pages with the Watch for livestock attribute.
As this is a long trail it would be really helpful if cachers would use the "needs maintenance" log or email us if there are any issues with any of the caches. We will then pick up on these quicker than if it is just mentioned in a "found" log.
For further details please see Hatley Heart Attack #1.
