Caching through Swansea I came across this complex. One thing that geocaching has made me aware of is just how many great athletic complexes there are out there, I guess you take these types of things for granted.
The cache is only just slightly into the woods, and there will either be no one here or loads of muggles here, so use the required amount of stealth. Bring some small tradables, bring a pen, and happy caching!
