You will want to park in the Island Centre and make your way across the street.
The fun with this one is the contents of the cache and not necessarily the find. It should be a rather simple find and go and there are enough items for all the kids to swap goodies. The cache is in a green box about 6” x 6” x 3”.
Look for it under an item you most likely used to get to the cache. It isn’t out in the open so you will have to do some searching.
