The Dakota Zoo is North Dakota's largest zoo, with 500 reptiles, birds and mammals representing 125 species. There are prairie dogs, mountain lions, bison and other animals native to the region. There are exotic animals from throughout the world, such as aoudads and yaks. Visitors can see it all from a train when they purchase a ticket to the zoo's train tour. There's also a concession stand, complete with popcorn, cotton candy, hot dogs and soft drinks. The Antler Trading Post carries an unusual selection of gifts and souvenirs.
