The gate to the carpark may or may not be open all day everyday, but, there is pedestrian access at all times.
Finding this one while there's a match in progress........Probably not a good idea, although not on the pitch, it's not a million miles off it!!
The day I hid the Cache, the place was crawling (Or rather, skimming across the water) with Kite Surfers.
The views across the lough from here are pretty good, and, although I didn't indulge, (Now there's a surprise) there's a nice wee wander along the shore to enjoy.
The Cache is a small screw top container with a few swaps and room for a small TB or two.
Best bring a writing implement with you.
