I hope others respond as well, as my time did not allow traveling the fullest extent of the country. In town (UlaanBaatar), you only need a day to get the main sights. I recommend the national museum - very detailed, much information, and quite educational. Just west of Chenggis Khan Square. You need to organize some trip that includes a ger. You'll be hitting the end of tourist season so the crowds won't be as bad and the temperature may even be 'pleasant.' Nights, however, can be quite cold in the mountains. A ger holds in the heat quite well and only chills down once the fire goes out. With enough layers you'll stay plenty warm. Terelj is beautiful with the fall colors, so be sure to see that. If you're fascinated by deserts, visit the Gobi. As I look at all the options, you have a wide assortment of other choices. Hopefully others will add to this and make your decision easier. (As I mentioned earlier, I'm limited!) Overall, I found the people fantastic! Enjoy!

Hi, Jeremie. I visited the Monastery last autumn, and it seemed to me that the territory is opened all night long, because I didn't see any big fence. It looked like a part of the city, some kind of a Buddhist quarter. Although all the temples are closed at night, I guess, but it is not 100% info. Good luck!

We didnt see the sign at the temple door so we didnt buy a ticket. My husband said, it is only a donation but we didnt give either.
