This cache is one of a series of new caches in Tommy Patten Millennium Park, on Holywood Road in east Belfast. The park has a playground, cycle tracks, basketball court, forest walks, football pitches... and some geocaches!
The cache is a camo nano attached to the local features of the park.
When retrieving the cache, please be very careful when opening/removing it - there are a couple of ways to do this and both will require you to reinstate it securely afterwards. Good luck!
