There are benches scattered throughout the preserve on the trails, as well as some picnic tables near the pond. At some points the trails were well marked, well at others it was less clear where to go. Great for a quick fix of nature not too far from the city. Probably will go again!

I liked how you had a two way lane to bike and walk. There was a lot of renovations on the Mt Vernon Trail going through the park and marsh area. It does get crowded there yet there was a lot of parking. It is parallel to Belle Haven Park. There were no nearby restrooms. You do hear sounds of cars & traffic along the Mt. Vernon Trail. The trail gets narrow at some areas and can get uncomfortable by the renovation area - close to oncoming cars. Bicycling through the woods over bridges and stopping by areas to enjoy the views were highlights we enjoyed at Dyke Marsh. We decided to just bicycle for an hour, yet it was enough for both of us. Looking forward to bicycling through all 18 miles of the Mt. Vernon Trail.

Dyke Marsh is a gem.

This wooded area with a trail that runs a bit more than a mile along the river, has owl and eagle nests and amazing guess of small islands in the Potomac. On any day, there are families, couples, people with dogs. The Marsh attracts lots of birders with their binoculars and photographers with seriously long zoom lenses. This is a place to amble for 45 minutes and connect with the natural world. It's managed by the US Park Service. If you're interested, join the Friend of Dyke Marsh to help preserve this treasure.

There are many creeks and streams that traverse the path on their way to going the Potomac. Despite going on Labor Day late morning/early afternoon, I only saw a handful of people several of whom were running with their dogs (no worries, no doggie land mines were encountered). I picked up the trail at the Theodore Roosevelt Island parking lot. There is a dirt footpath that goes from here to the American Legion Bridge (10 miles) and as mentioned before almost all of it is shaded. It may extend further, but I turned around at this point! There are parts were you will have to slow down your jog due to some uneven, rocky footing but have no fear, there are long stretches perfect for running. Someone must have come by and cleaned up the litter because it was pristine today! Huzzah!

On a hot day, walking in and out of the shadows of the trees was a welcomed treat as the hot breeze flowed by. The way the trail is set up is quite nice, wide, and enjoyable. I'm not sure where this trail actually starts and ends, but I feel like that segment that I walked would equate to an overall enjoyable trek to explore. I mean it doesn't hurt that it is near the water, and goes through some area where you can see a lot of things. It can come off as an open air museum as well with all the historic marks around it and memorials along the way. It's a good place to take your mind off things and let yourself disassociate.

It was definitely congested with bikers on the weekend. I mean, huge groups of cyclists. The Herndon part of the trail is not very scenic, it's mainly just greenery. There were a few water fountains and because it's passes through downtown, you can stop for a snack or a drink at any of the nearby shops. There's even a bike store right next to the trail. There's a cute small museum which used to be the train station. I couldn't visit it because it was closed. But I need to check it out. 5 stars. Pretty cool trail.
