The Harwell village puzzle cache series is not intended to be completed in a single walk and the caches will be published over a period of time to emphasise this. Each cache is located more or less within the parish boundary of Harwell.

This cache is a tree climb and you are looking for a bison. No special equipment was used to place the cache. As always, the decision to climb a tree is yours alone. If you feel that the climb is beyond your abilities then do not attempt it.
