Perfect for a stroller, and some nature scavenger hunts. The playground itself is huge and looked really well cared for. The toddler area was unfortunately closed during our visit, but the rest of the space more than made up for it. There are tons of benches and seating all around, and you can see most of the playground from just about anywhere, which is so helpful when you're keeping an eye on kiddos. There's a massive covered pavilion area that would be perfect for group meetups or a picnic in the shade. And while it was still closed for the season, the splash pad/water park area looked like fun! Definitely planning to come back in the summer to check it out! Such a great spot to have in the area!

Here's why you should visit if you're in the area: 1) Trails: There are a number of trails of all lengths perfect for a little hike with small kids. The trails are even enough that you could job on them, but they aren't paved so strollers are not recommended. 2) History: There are several plaques that tell the land's history being the property of a Revolutionary War hero. 3) Frisbee Golf: There's a long course with markers and all. 4) Workout Equipment: There are several stations to get a good arm and leg workout in. 5) Pond: There's a little pond that one of the trails leads to. Some even fish in it off of the dock. 6) Open Space: There are a few wide grassy areas on hills perfect for do walkers.

It's a nice course down around the pond, along the disc golf course, through the woods with changes of elevation, over the river on rocks, and back). The trail is well-worn and you may encounter runners, walkers with dogs, and bikers (though honestly for us it's been very few). The only somewhat bad thing is that it is very often muddy (but it's the woods so what can you do?!). There's a ton of parking, a tiny play area (I wanted to say playground but it's really not), and a floating dock at the pond where you can fish. This park is part of a bigger walkway/trail system which we have not as of yet explored. It would be nice if they had restrooms, so thankfully we live fairly close.

They have a giant lake for fishing, you can fish from the dock areas or bring or rent a non-gas powered boat. You can also rent a canoe or paddle boat but all the rental stuff is only open during spring/summer They have a 5 mile trail along the lake that's a nice walk but can be crowded when the weather is good and pay attention since the trail entrance isn't marked as clearly as it could be. They also have mini golf, a train, playgrounds and some other stuff. It's free for Fairfax County residents (glad we're getting something for our taxes) and $10 for everyone else but of course the rentals, mini golf, train, etc. cost extra. There's a decent amount of parking but go early on a nice day or you might have a hard time grabbing a spot. I'll come back here for sure to walk the trail and maybe do a little fishing or rent a boat

It has been an incredibly fun adventure for us - finding parks and places to enjoy, hike, and immerse ourselves in the nature, beauty of the outdoors, and wildlife in Virginia & Maryland. We walked all the trails in the Hidden Pond Park and liked spending time in the Hidden Pond Nature Center in the park. There are many activities for children and adults in the parks. The staff there were friendly and helpful. The park is well maintained and there are so many picturesque areas and hiking trails to experience there. We spent about three hours in the park. The park was peaceful and quiet. We experienced no traffic and saw very few people during our hike on the trails. Austin, one of the staff in the Nature Center, said it had to do with the geography & location of the park. Along the trails are many sitting areas to take a break. We saw many kinds of birds, deer, flowers, and foxes during our time in the park. Strongly recommend wearing bug repellent & sunscreen and checking out a map of the trails in the nature center. Beautiful park to visit during each season and very ideal for wildlife photographers and for peaceful & quiet walks in the park.

Pretty eventful day, April 15, 2026. Staff were helpful and nice! Nature Center provides wildlife education and animals, a place to refill water or use the utilities. I wouldn't expect to see all that we seen, as think we were pretty lucky to come across all of that in one day. For instance as soon as we sat down on the bench near the river, the hawk flew over and landed nearby, first to get a drink of water then perched nearby. The fox happened to be coming to the river before we locked eyes and ran off while I fumbled with my dang lens cap, as always. Good luck!

Came here with a group for kayaking. Only they ran out of kayaks before noon. So some of us had to…read morerent standup paddle boards instead. There is a slightly more expensive pricing for folks not residing in Fairfax, Loudon, Alexandria, or Arlington counties. But they don't really verify...so as long as you put down an address within those counties on your waiver, then you are good to go. See my pics for the pricing as of Aug 2023. The Sat I came, they seemed very short staffed with only two people managing the rental payments and forms and then another 2 manning all the boats/boards. So we pretty much ended up having to launch and bring back our vessels ourselves. They have very limited 2 person kayaks and they require kids under 12 to be in a boat with another adult so be prepared. In addition to kayaks they have jon boats and stand up paddle boards. You can bring your own vessel but there are launch prices. The lake is quite large so 1 hour is still not enough to explore its entirety even if you were powering through. The boat rental process is this: 1) Each person needs to fill out a waiver (just one page), you need to keep the yellow paper on you and return it when you come back. 2) Payments can be done per person or by group and they accept Apple Pay 3) Go down to the dock, hand them your form 4) They will tell you which vessel you can pick and hand you life vests and paddle(s) 5) Go have fun 6) Return the vessel 7) Bring back the yellow form to the rental house Not sure why we need to keep a piece of paper on us while out on the water. I've rented boats in many other places and all they needed was the vessel back. I guess to prevent theft...but they log the number assigned to the vessel on the form prior to you renting so...But at least there isn't an entrance fee to this park and there isn't really much else to do besides activities around the water front.

Several trash cans were overflowing, and there was litter scattered around the walking paths. The playground equipment also seemed worn down and not very clean. On top of that, the bathrooms were in poor condition and didn't seem to be cleaned regularly. It made the whole park feel neglected. Parks are supposed to be relaxing places to spend time outside, but this one just felt poorly taken care of. I hope the city puts more effort into maintaining it because it could be a really nice spot if it were cleaner and better managed.
