The Dare Skywalk

Stepping out onto the Dare Skywalk is the sort of thing you either commit to fully or chicken out halfway. It's a glass walkway that extends out over a significant drop, and the visceral thrill of walking on what feels like nothing is genuine - your stomach does register the void beneath your feet, even if your brain knows the engineering is sound.

The attraction sits in Hertfordshire, close enough to London that it's worth factoring into a day trip, particularly if you're already in the area visiting Theobalds Park just down the road. The view itself is decent rather than breathtaking - you're looking out over the landscape rather than down a dramatic gorge or across mountains - but that's not really the point. This is about the experience of doing it, the momentary vulnerability of trusting glass and steel.

It works best for thrill-seekers and families with kids old enough to handle heights without losing their minds, though younger children sometimes surprise you with their bottle. Budget an hour at most, including the walk-up and a few attempts at looking unbothered whilst your legs feel slightly unreliable. Go on a clear day if you can - mist or cloud cover rather ruins the effect.

The mechanics of booking and costs aren't entirely straightforward from a distance, so checking ahead online before you visit is worth doing. It's the sort of landmark that justifies a detour if you're already exploring the county, but not the sort of thing you'd plan a whole trip around.
