On December 15, 2005, Ottawa County acquired the 500 acre North Ottawa Dunes property. Just off the Lake Michigan shoreline, between the Grand River and the southern boundary of P.J. Hoffmaster State Park, this tract is one of the largest wooded dune assemblages remaining in the central West Michigan area. The property is uniquely situated between state, county and city parks and is adjacent to township-owned undeveloped land. This acquisition links P.J. Hoffmaster State Park, Ottawa County's North Beach Park, Ferrysburg's Coast Guard Park and undeveloped land owned by Spring Lake Township.
The property features tremendous topography with an elevation change of 185 feet in the parabolic dune formations. Eight distinct dunes in the rugged landscape exceed 750 feet in height. The property varies in width from 900 feet to 4,200 feet and has a north to south reach of approximately 10,200 feet (1.93 miles.)
