Wow -- this tour company was excellent. We tried 2 other companies - Tour radar and Viator. Tour Radar was good, but Juulchin was better. Viator tours we do not recommend.
Juulchin set up a tour at the last minute after a tour set up by Viator was a no-show the morning of the scheduled tour - in fact, the Viator tour guide did not answer phone calls or text messages - basically took our money and no one showed (we did finally get a refund from Viator, but not worth it.)
In contrast, Juulchin was at the hotel within an hour of the call. The driver and tour guide were fun, and interesting and the guide had excellent English and was a wealth of information. In addition to the statute, we visited a nomadic family that provided us with a horse tour. The lunch was one of the best we had in Mongolia.
We looked to see if we could use them for other tours but were unable to cancel prior scheduled tours. Juulchin will be our go-to when we return.
