Come spring, chances are there’ll be driving tours in fake panda cars along the A646 between Halifax and Todmorden, with overnight stays in dodgy-looking farmhouses. Happy Valley has done for Calderdale what Peaky Blinders did for Birmingham, and dark telly tourism is all about ticking off locations and looking the part (though I’m not sure hi-vis tabards will catch on). But there are three better, more active ways to explore the Calder valley. Two of these use the Calderdale Way, either the northern section or the southern, both of which involve hill climbs and traverses across fields, hedgerows, stiles – the usual argy-bargy of agricultural rambling.
