try behind the police station theres two gaps fron a fire escape to a wall to the carpark that looks very possible if a little dicey. there is a wall closer to the road that you can run up. then over the road opposite the police station go through the corner an office carpark and drop over the wood fence into the little road behind the high street. Then down by calverly park around the carpark is a few realistic drops and Im sure those windows have possibilities especially the ones above the stairs. I haven't explored much further yet.
oh yea, at the bottom of the pantiles is a private carpark with a chest hight wall dividing two ramps (on the far side) might be ok for practicing vaults with a varying degree of drop on the other side up to about 12ft.
Theres a choice spot on top of Pizza Hut, you can run from there right down to the opticians (cant rememebr the name). To get up there go to the car park behind Pizza Hut, theres a 6ft wall on your right, climb it and follow it onto the roof. Its a nice place to chill as well.
I went on Sunday- where the met was put off. Tunbridage Wells is overall quite a small and there are only a couple of good spots. Opposite the train station in the car park is good, and behind the police station is ok.
