Two good friends of mine live in Whitstable which is lovely, they moved there about 7 years ago after spending a few years in Folkestone. When they lived in Folkstone we’d always visit Dungeness which is also great.
I live in East Surrey a couple of miles from Kent, but go out in Kent quite a bit mainly to visit castles and stuff. Tonbridge is great, but I didn’t know about that beer place that @hip_young_gunslinger mentioned so I’m going to have to rectify that.
