I have one day left in Mongolia, and would love to get to Gorkhi-Terelj / Terelj National Park for the day. However, the only info I can find on getting there is on:
http://wikitravel.org/en/Gorkhi-Terelj_National_Park Which states there is a bus at 4pm there, and two buses back (8am and 7pm).
This seems odd as there MUST be a demand for day-trippers. Can anyone help out with info on alternate buses for getting there?
