Aden country park; A lovely spot, located in a little town/village called mintlaw.

Lots of good forest, a playpark (A few good opportunities here

) It has it's own caravan/camping site, but I think you have to pay for these, but the place is left pretty much unstaffed, (except the few who staff the farming museum and cafe) so as long as it's a little out of the way, camping is easily an option.
There's a ruined mansion with chances for cool climbups/wallruns/gaps/cat leaps etc. Not to mention a sizable dark scary pine forest, perfect for running through at full speed

I won't post any pics, as by the looks of things David's been here before, and a quick google yields a few pics. So, I live pretty close, and there are buses that run from Aberdeen bus station (the one at union square shopping centre) straight to mintlaw, where I could meet you all up and then it's a short walk down the road to the park. Maybe this could be the "something special" I had in store? What does everyone think?
