At the tip of the triangle formed by the meeting of the Monongahela and Allegheny Rivers is this park containing the Fort Pitt Museum , which commemorates the historic heritage of the French and Indian War. The renovated and beautified waterfront is popular during summer with strollers, cyclists, loungers and runners. For a longer run, head to the 11-mile gravel-paved Montour Trail , accessible by crossing the 6th St Bridge and catching the paved path at the Carnegie Science Center.
