OK, I'll throw one into the mix.
Come and see the Durham coast.
The soon to open Horden station will make an ideal starting point and excuse for a trip. Why visit? Natural beauty. The coastline has recovered incredibly quickly from the ravages of mining in the last centuries.
From Horden you can walk north to Seaham Harbour. This will take you along peaceful clifftops with fabulous views back to England's highest sea cliffs as far as Boulby, through the small but pretty Hawthorn Dene and it's isolated little beach, past 'The Blast' beach and along the promenade into Seaham, a once deprived town that now sports some great restaurants (including one with a Michelin star), an excellent ice cream shop, the much loved 'Tommy' sculpture and some cracking little bars. Get Carter fans will enjoy seeing the spot from the original movie's ending, as will Alien fans since the now much nicer beaches once stood in for Alien planets in the 1980s films!
You may spot rare orchids, butterflies and fascinating geology on your walk, plus there are some nice spots to photograph the passing trains.
Or head south towards Hartlepool, itself an underrated location. Again you'll walk along the fine clifftops and beaches if the tide is fair, under the magnificent viaducts at Horden and Crimdon, then end up at the Headland and the Heugh Battery (the first place in England to ever be shelled by the Germans!), perhaps sample some superb fish and chips at Verrills then walk or bus into town, where the northern branch of the National museum of the Royal Navy is situated, HMS Trincomalee and the PSS Wingfield Castle alongside more fine real ale pubs, the pleasant Marina and plenty of shops etc.
Yet there's more- from Horden it's not far to the magical Castle Eden Dene, a natural Limestone Gorge that runs around 3 or 4 miles inland, offers miles of footpaths and enough flora and fauna to satisfy even the most jaded of country walkers!
