Now that the storm has gone, this place really is an Ireland Paradise!
HT Ireland Reserve is a great park with multiple play areas for the kids, and an off-leash area for dogs. This park is also known as the Helicopter Park, due to one of the pieces of play equipment shaped like a helicopter that spins around and around. There is also a picnic table and brand new BBQ available. It's a great park to visit if you're in the area.
This micro-sized cache is hidden in a grove of trees a short walk along the path from the main play area. You will need to watch out for muggles as a couple of paths converge near this location. There is even a seat nearby where you can sit and ponder the location of the cache if you are having trouble :)
NOTE: you will need tweezers or an extraction tool for this one!
BYOP! And as always - good luck!
