West Mongolia is beautiful - you need to see it to believe it. Should you want to visit the Altai mountains, you will need a longer travel period to pace and drive, and of course this would cost more that just seeing it from afar. But both, amazing.
Best part about my 10D travel is that i did not have to worry about Halal/Muslim food - good to inform operator if you are on any other strict diet for them to arrange the delicious local delights and home-cooked meals.
Cook, Driver, Guide are all so friendly and welcoming, I thoroughly enjoyed the authentic experience from A-Z. From the sights and sounds, to the activities to random-things-to-do, the operator can pretty flexible with your itinerary.
Do some research and let them know what you want to see/ do for them to personalise your trip, or simply get them to arrange something for you all-in within your travel dates - they know best what's lurking in between those mountains!
I'd recommend and come back anytime with NAT LLC - hastle free! (:
