For the PATC Challenge, any hike on National Trails Day counted, so we took advantage of this to make a Pride-month appropriate visit to a trail that had been on our list for a while - Dyke Marsh Wildlife Preserve. This is a short, one-mile flat trail in Alexandria, starting from the Mount Vernon Trail.
The difficulty level was very low, of course, but we saw wildlife, including a little green snake. Some volunteers were out planting trees, too. At the end of the trail, which is mostly gravel turnpike, is a boardwalk with views of the Potomac.
