Trekking outside Karakol means trekking in the Terskey Ala-Too mountain range, which is part of the Tian Shan range. The three most popular valleys are Karakol Valley, Arashan Valley and Jeti-Öghüz Valley, which are all connected to each other through mountain passes. The scenery is just spectacular with racing rivers, alpine lakes, and snow-covered peaks above 5,000 m. There are lots of tough-looking, but very friendly, shepherd families with their herds of sheep, horses and cows in the area. It's usually fine to camp in an undisturbed spot – but beware of the shepherd dogs, they are vicious. In Arashan Valley, which is famous for its hot springs, there are even simple lodges at Altyn Arashan, making it the perfect destination for those without camping and cooking equipment. Trek in and make Altyn Arashan the base while doing day trips into the neighbouring valleys.
