The Blair Witch is one of 2016's most shart-inducing horror films.

Tense, claustrophobic and utterly nerve-jangling, it doesn't get any more jangly than the moment that heroine/Witch stalkee Callie finds herself trapped in a very tight space, and has to squirm, crawl and scream her way through an increasingly tightening hole as the titular crone leers somewhere behind.

MTV was invited down to deepest, darkest Derbyshire (beautiful up top, terrifying down below apparently) for the chance to experience that feeling ourselves, through the joy of potholing with Dolomite Trianing.

Things got claustrophic-y.

'Blair Witch is available on Blu-ray, DVD and digital platforms on now.'

'MTV Travelled With... Dolomite Training (who offer an array of thrill-seeking experiences, including cavin), stayed at Buxton's The Old Hall Hotel, and captured all the cave-adventuring footage on the Olympus TG Tracker. '
