Tower Tour Posted December 19, 2013 Climb the tower to take in the spectacular view of the Straits of Mackinac, the Mackinac Bridge, and several nearby islands. Tower tours are guided by an historic interpreter every 15 minutes. You will be assigned a tour time when you purchase your admission ticket. Climb 51 steps to the watch room before continuing up the 13-rung ladder into the lantern room, where the Fresnel lens once rotated. Your climb will be rewarded with a sweeping, panoramic view of the Straits of Mackinac! For those who wish to remain on ground level and still experience the tour, a video of the tour and spectacular view is available to watch in the base of the tower. Guidelines To climb the tower, you must be at least 4 feet tall and wear secured shoes. Flip flops are not permitted. Read the complete “Tower Tour” Guidelines.
