Forbidden Corner Yorkshire Dales National Park

There can surely be no other place like this in the world: a modern walled garden furnished with Victorian-style follies, some veering into gothic horror, others merely surreal fantasy. There's no map, so it's a case of diving in to explore the many tunnels, twisted turns and dead-ends – an experience that may make you feel like you've fallen into David Bowie's Labyrinth. Small children are guaranteed to feel scared witless at some turns; adults may leave feeling a little rattled, too. Tickets must be pre-booked.
