The dunes that frame Crescent Lake are the eastern edge of the Kumtag Desert and rise to over 250 metres above the surrounding plain — high enough that climbing one is an actual workout. The standard programme is to take the wooden ladder-staircase up the steepest face, watch the sunset from the ridgeline, and either slide down on a wooden toboggan or simply tumble back to the bottom in the sand.
Camel trains leave from the entrance gate and walk a circuit through the dunes; it is touristy but undeniably atmospheric, especially in the low light of late afternoon. Sand-skiing, dune buggies, microlight flights and a small zipline are available for those who want them. The site shares an entry ticket with Crescent Lake — buy one ticket, see both.
