A few days in the glorious Peak District for those who want a shorter travel time and shorter routes than Scotland...
For climbers, Stanage Edge alone has enough to keep you going for years; there are a ton of other top-quality gritstone crags around, as well as some excellent limestone (trad and sport). Bouldering is also an option if you must.
For walkers, there are countless options in the Dark and White Peak, of which Mam Tor and Kinder Scout may be the best known.
Other activities include mountain biking, caving and wild swimming. Rainy day options include the Swearing Caves of Dovedale (http://viz.co.uk/2015/06/13/the-swearing-caves-of-dovedale/) - er, I mean the show caves of Castleton - plus the obligatory gear shop faff in Hathersage and the metropolitan delights of nearby Sheffield.
We'll be camping at the wonderful Hardhurst Farm just outside Hope.
