Video: Stephen Bleach walks the skywalk

If you’ve ever seen a Road Runner cartoon, you’ll know that in every episode, there is a sequence where Wile E Coyote runs off a cliff and just keeps on running — until he looks down. Seeing nothing but thin air under his feet, he promptly plummets to the earth far below.

Well, now I know exactly how Wile E Coyote felt, but without the unfortunate gravitational consequences. Last week, I strolled onto the Skywalk, a glass-floored, horseshoe-shaped walkway that juts out over the precipitous rim of the Grand Canyon, deep in Road Runner country. Like a scene from a vertigo-sufferer’s darkest nightmare, it suspends you in midair 4,000ft up, with nothing but 4in of clear glass between you and the distant, jagged rocks of the valley floor. If you fell from here, you’d have quite a while to ponder the transience of life before you proved it.

Despite the perilous position, it is, the engineers claim, as safe as houses.

At a cost of more than £15m, the walkway has been built to exacting standards, its 6ft deep girder beams anchored in place by 108 steel supports driven 40ft into the rock. The tempered glass beneath my feet was made in five layers for extra strength. They reckon it could support 822 people with ease, considerably more than the 120 who’ll be allowed on at any one time.

I knew all that as I climbed the steps to the walkway, but knowing something in your head and knowing it in your heart are two different things, especially when your stomach is starting to turn somersaults. The first steps out into the void were electrifying, the ground melting away beneath my feet, to be replaced by a tumbling vista of hundreds of stunning strata. It’s a sheer, unnatural high.

The sides are glass, too, reaching up to about shoulder height, though the top is open to the elements. Looking for the best viewpoint, I made for the furthest reach of the walkway, in the hope of grabbing a little quiet time to contemplate the mystery and majesty of the ancient rocks spread at my feet. And I was starting to do just that when I made an interesting discovery. If you’re one of those vertigo-sufferers I referred to earlier, it might be worth skipping this bit, because, despite assertions to the contrary from its managers, the Skywalk wobbles.

It’s nothing pronounced, nothing dangerous, just a slight tremor from the wind and the tread of your fellow visitors’ feet, but it was enough to bring a small whine of panic from a couple of my fellow musers as we stood there, contemplating the fact that terra firma was 70ft away. As Norman Foster found out to his cost, wobbly structures are not something the public generally relishes, but it’s remarkable how quickly you get used to the slight movement — and in any case, for the thrill-seekers who are likely to be drawn to the Skywalk, it can only enhance an already heart-in-mouth experience. Within minutes, the drama of the setting overcame any fears, and I ended up loving it. I was soon enthusiastically jumping up and down to see what this baby could take.

But any impact I could make was drowned out by the pounding feet of the mob of journalists coming up behind me. The opening event was a media scrum, and, though I’d sneakily got onto the walk before the mob, I was soon surrounded by a posse of television news crews, each trying to create the illusion of seclusion by shouting at their rivals to get out of shot. It didn’t help that a nasty Arizona dust storm had blown up, sandblasting the lot of us. The presenters’ eyes were red and watering, their blinding white grins dulled by a coating of fine desert grit as, one after another, they delivered the obvious catch phrase of the day — “It’s like walking on air.”

WHEN THEY’RE first allowed access on Wednesday, the general public will probably be a lot more polite and considerate than journalists ever are, but getting space to contemplate the experience is still going to be an issue. Perhaps my expectations were too high, but the structure itself looked surprisingly small close up. The walkway totals 140ft, so even if you’re not dodging irate cameramen, it might not be the most serene experience with a full load of 120 people on board.

In fact, amid all the understandably excited media coverage such a radical structure has provoked, one thing hasn’t come in for much consideration: what will it actually be like for visitors? Will it be worth the time and money to have a stroll on Skywalk yourself?

You’ll need a surprising amount of both. Skywalk isn’t at what most of us think of as the “proper” Grand Canyon: the South Rim, where 90% of visitors end up. It’s at a Native American reservation called Grand Canyon West, a narrower part of the chasm more than 100 miles away. While the view is undeniably impressive, you don’t get that phenomenal vista of buttes, mesas and spires here. There isn’t much accommodation, either, so most Skywalkers are expected to visit on a day trip from Las Vegas, a good 2½hour drive away, some of it over dirt roads. Five hours is a long round trip for a short walk.

Once at the reservation, you’re not allowed to drive around yourself, but have to take a coach package to see the various lookouts (including Skywalk’s Eagle Point eyrie) and a reconstructed Indian village. The cheapest is £26pp, and you’ll pay an extra £13pp to walk the Skywalk.

So, is it worth it? If you want to share in that Wile E Coyote feeling, the answer has to be yes: there’s nowhere else on earth where you can walk straight off a cliff and not end up spread very thinly over a very wide area. If, though, the view and the sense of space are all you need, here’s a tip: head instead for the South Rim and make for Shoshone Point, a high, often deserted promontory where the rock juts out into the void, leaving you surrounded by thin air on three sides. The view’s better, the price is lower, the atmosphere’s more tranquil and contemplative — and, on top of all that, it doesn’t wobble.
