The Harrat Uwayrid is a dark lava field, a tilted plateau of black basalt that rises along the western edge of the AlUla valley, and the viewpoint here looks down from its escarpment over the oasis and the sandstone country below. Harrats are the lava fields that spread across western Arabia, laid down by volcanic activity over millions of years, and their dark, rubbly surfaces contrast sharply with the pale and orange sandstone beneath. That colour contrast is the whole picture: a black lid on a rusty cake.
From the edge you can see the valley floor, flat and green where the date palms grow, and the wall of cliffs on the far side, shining in the afternoon light. Roads thread across the plain like pencil lines, and in the clear air the horizon seems to go on forever. The oasis exists because groundwater collects along the foot of these cliffs, and people have farmed here since ancient times, long before the Nabataeans built their tombs nearby. The silence at the viewpoint is broad and deep, broken only by wind and the occasional raven.
The ride up is a pleasant one, with a smooth road winding up the escarpment in gentle bends and rising steadily to the plateau. Surfaces are generally good, but gravel and sand can wash across corners after rare storms, and strong winds on the exposed edge can push a bike sideways, so hold the bars firmly and stay well back from the drops. The coolest, clearest hours are early morning and late afternoon, and the cooler months from autumn to spring are by far the best time. In summer the heat shimmers off the rock and the air is searing.
There are no services at the viewpoint itself, so bring your own water and some shade if you intend to stay. AlUla, about eight kilometres away, has petrol stations, shops and restaurants, and the sensible approach is to fill the tank and top up your bottles there before you climb.
If you have time, stay for sunset. The black rock cools quickly, the valley fills with long shadows, and the lights of the town begin to appear below.
