Shhhhh! Don’t read this too loudly.
Thank you for agreeing to help.
As our newest covert operative, we require you to collect certain important material which will lead you to a special rendezvous.
The co-ordinates above (N 54° 42.988' W 6° 13.546') will take you to the “Bridge of Spies” where you will observe the information needed. You should try to go in disguise so you cannot later be recognised.
The final rendezvous (location of the cache) is nearby but two digits are missing – this is the vital information you must collect. The second last digit is obtained by counting the number of arches (an arch can be passed through from one side to another). The last digit can be obtained by counting the number of “step-outs” (look like seats – but aren’t) on the bridge itself.
N 54° 43.043' W 6° 13.9(arches)(step-outs)
Tree cover near the cache will affect the GPS signal. Many counter-operatives patrol the area disguised as muggles, often with guard dogs. Be careful and approach the final rendezvous stealthily.
Good luck, don’t get recognised, don’t get caught and stay safe.
The Cache
The cache is a small tab-lock box wrapped in eco-friendly material. Contains a logbook and a few swapable items. Please replace carefully.
The Boring Bits:
So this is a puzzle cache located near Antrim Castle Gardens that’s meant to be a bit of fun and a bit different. The puzzle isn’t exactly hard but I’d like to encourage you to upload a photo of yourself in disguise on the bridge. (You only need to be in disguise for the photo and can take it off to find the cache). Your disguise can be as elaborate or simple as you want. I’ve got things going by including my own photo (including suitably unrealistic fake moustache).

When you log your find, why not include one of those corny cryptic messages such as – “The water in the river is unusually dry this time of year”.
YOU DO NOT HAVE TO BE IN DISGUISE OR UPLOAD A PHOTO TO LOG THE CACHE
but why not join in, what’s the worst that could happen?
Car Parking:
Parking is available at: N 54° 43.083' W 6° 13.547' but please check closing times.
Alternatively, you can park in the nearby (signposted, free and open 24 hours) Antrim Central Carpark and enter the Castle Gardens on foot (2 minute walk). The Gardens can always be accessed free on foot.
The Really, Really Good Bit:
This is an excellent area to take your four-legged best buddy for a nice walk. There’s even a purpose built play-park nearby where dogs can socialise and exercise together.
