Repetek has the reputation of being one of the hottest places in the former Soviet Union, and on a summer afternoon in the Karakum desert, standing among the dunes with the air shimmering, you will not doubt it. A desert research station was founded here in 1912, and the surrounding area became a nature reserve, later a biosphere reserve, protecting a typical stretch of the sandy desert of Turkmenistan. Scientists have studied the plants, animals and dunes here for over a century, and the station has been a pioneer in understanding how life survives in extreme heat and drought.
The landscape is a sea of sand ridges, some bare and shifting, others anchored by saxaul, the small, twisted desert tree that is the backbone of life here, with roots reaching deep into the sand. Black saxaul and white saxaul grow in groves that provide shade and food for animals. The wildlife is mostly active at night and in the cooler hours: gerbils, jerboas, sand cats, foxes, monitor lizards and snakes, and a rich variety of beetles and other insects. In spring, after the winter rains, the desert briefly comes to life with flowers and grasses.
Repetek sits beside the main road and railway between Mary and Türkmenabat, which follow the route of the old Trans-Caspian railway built by the Russian Empire in the late nineteenth century to link the Caspian Sea with Central Asia. The road runs for long stretches across the desert, straight and monotonous, with a surface that can be very poor, with potholes, ruts and drifting sand in places. Heavy trucks use it, and the heat haze can make distances deceptive. In summer, ride early in the morning and rest in the middle of the day; the risk of heatstroke and overheating, for both you and the bike, is real.
Turkmenistan requires visas and, for most tourists, a guide, and transit visas have fixed routes and limited time. Fuel is cheap but available only in towns such as Mary, Bayramaly and Türkmenabat, so plan your stops carefully and carry extra. There is little or nothing to buy along the desert road, so carry plenty of water and food. Türkmenabat, on the Amu Darya, has markets where you can buy melons, famous throughout Central Asia for their sweetness.
