Private transport
From Ulaanbaatar to Murun
It is not possible to rent a car without driver in Mongolia. If you have brought your own car, it is worth to buy Mongolia Road Map, although you will find out that driving a car in Mongolia can be demanding due to the quality of roads (just few percent of them are paved).
Arranging private transport with local drivers is not complicated, as everyone is potential driver, just have to clarify the price and make sure he/she knows the way. HATI can organize you private transportation in reasonable and reliable circumstances.

How to get to Ulaanbaatar

For travellers from Europe and Russia might be Transsiberian Railway (connected to Transmongolian Railway on the way Moscow - Ulan Ude - Ulaanbaatar) the most interesting option. It provides unforgetable experience and eco-friendly way of transport.
Arriving by plane, most flights changes at Beijing, Moscow, Seoul or Istanbul based on your departure location. From these places several direct flights are operated on daily basis.
