The Milton Keynes Boundary Walk is a circular walk approximately 65 miles long around the boundary of the Milton Keynes Unitary Authority; it is waymarked with the Oakleaf symbol.

In 2012 a group a local geocachers divided the walk into sections and set a series of over 300 caches along the boundary.

Please note: the "Caching the Boundary" website is no longer available and the intention is to archive these caches at the end of 2015.

This is the twenty first cache in this section. It contains information to help you find the indigo bonus cache, which is hidden near the middle of the section.

This cache is a small clip-lock box containing log book and pencil with room for a few small items. Terrain grading is due to distance if doing the whole section. Difficulty is due to tree cover, which might mean the co-ordinates are not very accurate.

The wind turbines in the distance are the Milton Keynes wind farm at Petsoe End.
