How far do you want to go?
Just follow the lakeshore, north or south out of the park, the Shoreline Route, or something like that.
North it goes about 10 miles to Muskegon, where you can hop on a paved trail around to the north side of Muskegon Lake, then Lake Ave. west along the north side of Muskegon Lake all the way to Lake Mich (at Muskegon State Park), then north along Lake Mich all the way to Whitehall.
Or...south to Grand Haven, hug the shoreline along Lakeshore Dr. to Port Sheldon, Holland and beyond.
Good stuff either way.
