Gasoline-powered vehicles are prohibited except for an ambulance and a fire truck. Guided tours of the island are conducted from horse-drawn carriages. Many of the horses on the island are large draft horses bred to pull the heavy carriages and cargo wagons. There are also horse-drawn taxis, small rental carriages, and horses for riding. The eastern shore has extensive shallows formed from layers of the rock that makes up the island.
Trees cover the surface of the island, but are limited in height by the shallow topsoil.
The most spectacular view on the island is through Arch Rock. Natural erosion formed the arch as softer rock was leached away by flowing water. The highest point on the island is at Fort Holmes. You can see the island, two Great Lakes, and the Mackinac Bridge. The Mackinac Bridge is one of the longest suspension bridges in the world as well as one of the most graceful.
