In September I went camping for one night just outside of Hustai park. September is already pretty cold in Mongolia, but I made it through the night with a super warm sleeping bag and several layers (including a hat). However, I was pretty cold most of the time, and that was definitely the last camping outing for the season.
Hustai is a national park about three hours from UB, and its famous because it’s the protected area for the Takhi horse. Takhis are genetically distinct from domestic horses and used to be extinct in the wild before they were reintroduced to Mongolia (from zoos). They want to keep them wild so you can’t get too close to them if they aren’t on the road, hence the pictures from afar.
You’ll also see a picture of some stones with faces carved, in Hustai there are also some really old stones that according to at least one internet source date to the 6-8th century AD. Throughout Mongolia there are sites with ancient artifacts and what they call “Deer Stones;” this was my first time to see any.
