please bring extra comfortable shoes, pants and socks, some places would be requiring light hiking. You may bring your snacks during the trip because it will take a long journey on the road. Please bring enough tugrik /mnt/ for local food/snacks (perhaps your alcoholic drinks), souvenirs or other purchases since there would be no money exchanges in local provinces and during the trips). It would be advisable /optional/ to bring with you some extra candies or sweets, perhaps if we visit some nomad family or gathered by children in a remote area and give them, would make them happy as well as add some charm to your trip ☺. (for Mongolians it is kind of an unwritten custom when traveling to the countryside or visiting nomads).
