Ala Archa is my first national park in Central Asia that looks maintained. No one's sitting in a visitor center handing out maps, but Ala Archa has everything you really need: Regular trail markings, the occasional sign post with kilometers to the next landmark, and a little cafeteria at the base of the park that sells light snacks on the cheap.
Along the south shore of Issyk Kul, near the village of Barskoon (Барскон), the single road that hugs the perimeter of the lake splits off to the left. This was once a Silk Road shortcut, providing access over a towering mountain pass into China. Now the road is largely maintained by Canada.
