Great walking trip. Coming from someone who does zero exercise usually, it’s a very easy and enjoyable hike. In total it took myself and my parents roughly 5 hours to see everything (including loo breaks and refreshments) over a course of 7 Miles. There was flooding around the Tidal Basin sidewalks so we had to detour slightly further out. But the views are simply stunning. However it was a very humid hot day which did take its toll!
