• Friday, 23 July 2004 : Go around in Houghton / Hancock and visit McLain State Park
• Saturday, 24 July 2004 : Mackinaw City, Mackinaw Island, Sault Sainte Marie
• Sunday, 25 July 2004 : Sault Sainte Marie Locks, White Fish Point, Grand Sable Dunes, Munising
• Monday, 26 July 2004 : Porcupine Mountains, Misery Bay
• Tuesday, 27 July 2004 : Eagle Harbor, Copper Harbor, Brockway Mountain, Fort Wilkins, Lac La Belle, Bete Grise, Lake Linden
