I was born there, and used to live in Southborough, between T Wells and Tonbridge. It’s very nice, a bit provincial and clicky, Pantiles is very quaint, often used on TV, great cookwear shop, it’s got a very middle class whiff but believe me it’s got all the usual rough estates that makes this country so great. The surrounding Weald countryside is very beautiful, Penshurst, Speldhurst, Chiddingstone etc etc. Country pubs galore. MTB ain’t great, lots of muddy bridleways, yes Toy’s Hill up the road but the trails are mainly full of dog walkers, some fairly decent XC on the Greensand way heading over Crockham Hill.
Some nice rocky bits too, High Rock and one that looks like a Toad 🙂 Lot’s of Steam Railways in the area if that’s your thing or have young kids.
