Altyn Arashan Gorge
You'll need to undertake a long journey in a four-wheel drive (allow half a day) to reach Altyn Arashan Gorge, renowned for its sulphurous waters said to cure skin complaints and respiratory conditions. Very popular with the Russians and the Kyrgyz, it is now an assembly point for western travellers, who set out from here to roam the valley on horseback. The high point is the Ala Kul pass, where you can take in the gorgeous scenery of the high mountain pastures. For hikers of all levels.
