The desert east of Isfahan does not announce itself with drama. The green of the Zayandeh Rud valley thins out, the fields give way to gravel and salt-bush, and somewhere past Kuhpayeh you are in the dry heart of the Iranian plateau, with the Dasht-e Kavir somewhere beyond the horizon. Neyestanak is a small settlement out here, and the reason anyone lists it is water, or rather the clever way people have found it for roughly three thousand years: the qanat.
A qanat is a nearly flat tunnel, dug by hand from a series of vertical shafts, that taps groundwater in the foothills and walks it downhill to the fields without a pump or a drop of evaporation. From the air the shafts look like a line of ant-hills marching across the plain. The one associated with this area goes by the name Qanat of the Moon, and it belongs to the family of Persian qanats that UNESCO has recognised as a masterpiece of hydraulic engineering. The skilled diggers, the muqannis, were a respected trade; a good one could sense the slope of a tunnel in the dark, and the families who owned shares in the flow traded them like land.
For a rider the interest is quieter than a castle or a pass. The roads here are long, straight and very empty, with the occasional line of power pylons and a truck or two. Heat is the thing to plan around. In summer the plateau bakes, so mornings are the honest time to ride, and from late autumn to spring the light is wonderful, low and golden over pale hills, with snow sometimes dusting the Zagros far to the west. Wind can lift sand across the tarmac without warning, and the horizon is so wide that distances lie to you.
I will be straight about the practicalities. This is not a place with a visitor centre and a car park. If you stop, stop where you can pull right off the road, take your water from the bike rather than hoping for a shop, and ask in the village before wandering near the shafts, which are open holes and can be deep. For fuel, Kuhpayeh is the nearest sizeable town on the main road, and Isfahan, a big city with everything, is within easy reach to the west. Carry more than you think you need, because the gaps between pumps in this country can surprise people used to Europe.
What stays with me about places like this is the patience of it. Nobody built a monument here. They built a ditch that works, and the work has outlasted dynasties.
