Yolyn Am was originally established to conserve the birdlife in the region, but it’s now more famous for its dramatic rocky cliffs and narrow, heavily shaded canyons that allow sheets of blue-veined ice to survive well into the summer. Yolyn Am is in the Zuun Saikhan Nuruu, 46km west of Dalanzadgad (return taxi T100,000, one to two hours).
