The Maah Daah Hey trail is supposed to be one of the best mountain biking trails in the United States. The trail is dirt and in some places, very rutted. The trail is also used by hikers and horseback riders. The trail runs from the north unit of the Theodore Roosevelt National Park to the south unit and Sully Creek State Park. I have heard the 5 mile section around Medora is supposed to be the hardest. I have biked this section several times.
Chateau de Mores is a nice historic house located on the edge of town. It was built in 1883 by Marqius de Mores of France, as a hunting lodge and summer home. There are several tours a day that go to the chateau. Tickets can be purchased at the museum. Check with them for schedules and prices. Behind the chateau is a small trail, and some stables, which you can visit on your own. If you're gonna be staying in Medora or Theodore Roosevelt National Park, and you have some extra time left over, it's worth visiting.
hiking the back trails or take a horseback trip through the nice trails they have provided.
By way of horseback you kind of feel like you have stepped back in time to the old west.However,hiking is great as well but have good hiking shoes and lots of water.
This is the south unit of the national park. It's main gate is in Medora. There are many places to hike, and usually see a lot of wildlife.
