Entry & Exit Formalities
Permits are required for Dariganga; you'll hit checkpoints on the roads leading into town, so have paperwork in order and register yourself with the border guard.
If you are coming from Dornod you shouldn’t have any trouble getting to Shiliin Bogd and on to Dariganga; this allows you to travel directly from the Khalkhiin Gol area and Dornod Mongol Strictly Protected Area, bypassing Choibalsan and Baruun-Urt. This is the most scenic drive in eastern Mongolia and will be faster than heading back through Choibalsan. Make sure you have this route listed on your border permit.
