The closest nice (and maybe closest as well) camping spot to DC. Just head down Route 1, past Ft. Belvoir, and you'll come to this nice regional park featuring camping, swimming, playgrounds, mini golf, frisbee golf, and kayak, paddleboat, stand-up paddleboard, and canoe rentals.
I went for the camping, because it was the weekend and I needed to get out and I waited to the last minute and didn't want to do with the two-night minimums at lot of the privately-owned campgrounds in the region force. Pohick Bay, at $25 a night, fit the bill.
The campsites are set around a open field and playground. At night, along with the fireflies, the tweens rules, running about with all their wild hormones until their parents tire of the worry and noise and corral them into their tents around 9pm. There are campsites toward the back that do not get to listen to such banter but I was not that lucky.
Most sites feature electrical hook-ups, in addition to a picnic table, fire pit, and charcoal grill. Several trails lead from the campground down to the Potomac and the aforementioned rentals. Good times.
Spring 2011 Update: They really need to bite the bullet and regrade the 13th green. It is sloped too steeply and it has been a problem for many years. When you can not stop a ball on the green from above the hole or below it (a putt that misses the cup from below the hole will come all the way back to you and then some), that is a problem. It is enough to make me consider finding a new home course.
I drive about 25 miles from Maryland to play this course more than any other. As others have written, it is a course for shotmakers, heavily tree-lined with lots of dog-legs and a few blind tee-shots. The range, chipping and practice greens are all close to the clubhouse and the tee-boxes for #1 and #10.
If you like getting in a walking workout while you play, the hills on this course will put you through your paces.
Played this course yesterday. Course was in great shape. The greens were just aerated 8 days ago and were close to being fine. Fairways were nice and the ProShop is great. Staff was friendly also. The only negative in my book is no grass driving range, just mats.
Lovely when it's warm out. I've held a ton of kids parties here. Also great for dogs and children to run around and play at. Great deals on the boat rentals too!
