Moat Park.
People travel through Dundonald en route to Belfast or Newtwnards. Moat Park, in the heart of Dundonald, provides a green oasis with walks around the historic motte. This area has a lot of memories as P lived nearby as a child and walked through the park to attend the local school and youth organisations. For example, this is where he heard about the assasination of JFK on his way home to see the first ever episode of Dr Who! Other memories include looking for sticklebacks in the Enler river, sledging down the side of the motte during the heavy snows of 1963, and, more importantly, enjoying a first kiss!! Hence the FTF prize is a heart-shaped key ring and the cache has been placed in time for Valentine's Day!
At the posted coordinates information can be found that will lead you to the final cache. .
