Mile 4 is situated at Point aux Pins at the northernmost point of the island. Here, M-185 turns southerly, passing the state boat dock and a nature center before coming to British Landing at the intersection with British Landing Road. The area is a popular stopping point for tourists biking or walking M-185; it is the location where British troops came ashore during the Battle of Mackinac Island during the War of 1812. Located around British Landing are various amenities including restrooms, picnic tables, and a concession stand. M-185 continues along Maniboajo Bay and passes the mile 5 marker near Radisson Point.
