The Khongor Sand Dunes, also known as the Singing Sands, are one of the largest and most impressive sand dune systems in Mongolia's Gobi Desert. Stretching over 180 km, these dunes offer a stunning landscape for exploration. Accessibility is challenging, requiring a 4x4 vehicle and experienced driver due to the remote location and sandy terrain. While solo visits are possible for experienced desert travelers, a guided tour is highly recommended for safety and logistical support. Seasonal restrictions may apply during winter months due to extreme cold. The cost of a visit varies widely depending on transportation, accommodation (ranging from ger camps to basic guesthouses), and tour options, but expect to spend at least $50-$150 per day. A typical visit duration ranges from 2 to 3 days to fully experience the dunes and surrounding area.
