It is described simply as an “activity wall” — both on the website and by the friendly staff, who act as if you are about to take a gentle stroll to the local souk. What it actually is — as I discovered once I was already strapped into a harness and clipped to a metal wire 10 storeys up — is a nerve-shredding 200-metre climbing route running along the side of the fabled Green Mountain, the highest point in Oman. It also features a zip line, plus a terrifyingly wobbly cable bridge suspended high above the valley.
With trembling legs, I tentatively — and with the occasional cry of “seriously, though, is this nearly over” — worked my way around the trail.
