I wonder how the Mongols liked the playground. It's not a very exciting playground, but if you're staying in one of the "Gers", it would be a fun way to wear down the kids.
One recommendation I have is to not bother with the car on the track here. It costs 300-yen per person (including kids) round trip to go out to the point and back. It isn't a far walk.I took this photo from where the rail car track starts. That's an agility course for dogs down there.
There weren't many visitors while we were there, so we had our very own guide. He pointed out that island out there. It's called Lion Island. Another island just beyond the Lion is an island that looks like someone laying on their back sleeping.
You can stay in these Gers (Yurts). They house up to four people. It was extremely windy the day we were there and these didn't seem to suffer at all.
They have costumes you can try on at the front entrance. I think you have to pay to try them on.
Entrance fee for the village is 200-yen for adults.
