The camels go around the dunes. Apart from us, there are no other people to be seen. Just the three of us on our camels and our guide. You can book tours directly in Mongolia, we organized them from home.
We planned and booked our tour from home. We were even able to book vegan food during the tour and it worked well on site. Waterproof bags or backpacks are important. Camping equipment and good, sturdy tents, as there is often a very strong wind.
