A federally run museum perched on a bluff above the North Platte, dedicated to the great westward migrations of the 19th century. The exhibits are unusually well-mounted for a regional museum: mock wagon crossings of the Platte (you sit in a covered wagon while the floor rocks), Pony Express recreations, Native American perspectives on the migrations, and a thoughtful section on disease and death on the trail.
Allow ninety minutes to two hours. Free; the bluff itself gives a fine view across the river valley toward town. Closed Sunday and Monday in winter.
