Weather fine - so don't think you have any worries there. Which direction are you coming from? If motorway (M6 J7) follow A34 stay in left hand lane so you don't go over the fly over - sweep round to the left and car park entrance on the left. If coming from direction of city centre make sure you come off flyover/underpasses route before Perry Barr, you need to go straight over at Perry Barr roundabout - stay in right hand lane, following road underneath the flyover, then bear left - car park entrance on the left. Hope that makes sense!
