Late may early June
Second week in June to the second week in July. My preference would be the first two weeks of July
Summer, the town of Medora and the Medora Musical are a must see if you're in the area.
I would call the park it will depend on how much snow we get. Either way any time there is always something to see. The park people can tell you when it's very crowed and when it's not and also when the baby Bison are able to be seen.
I went in August it was great but what I would like to do is go back in full on winter with snow love to take some pictures of Bison half covered with snow
I went the second week of September, it was no crowded at all and the weather was fresh. I loved it.
Summer months for sure
I agree as it's only open from June through August
We have gone in fall. Not crowded, great wildlife viewing . That,would be in September.
I was there the first week of September and it was beautiful. The crowds are also smaller then.
