Peaceful and beautiful trail :)

It’s fine for a short, close to town jaunt. If the rating was easy I’d give it four stars, but I expect a little more activity with a moderate hike, and this was just a nice stroll near town.

There are lots of ticks. Next time I’m taking bug spray!

Fun for family hiking. A lot of wildlife out and about. Took a few snack and water breaks along the way. Took a couple hours to hike. But overall was a great quiet hike.

A very pleasant five mile walk in the woods. A few spots are close to highways, but given its location, much of the trail (especially the southern part) was quite nice.

It is a nice place inside the Beltway to go for a relatively easy trail run and it is so much better than running on the roads. It for all the times I have been there, it has never been busy.

Not much to see. But good for the purposes of exercising.

Light traffic. No issues. Quite peaceful. Did 6.7 miles starting at Dogwood trailhead. Good markings. No ticks on me but I kept sitting.

Nice trail though highway views kind of takeaway from scenery

Walked most of the trail during an overcast, chilly day. Easy trail to hike (fairly well marked and no major elevation gains) and run. Not much to see in the winter but probably pretty in the summer.

Pleasant, easy, well-marked. Virtually no elevation change.

Close to busy roadways, but otherwise great trail.

This is my go-to trail when I want to get in a nice walk near home. No bugs today, a young fawn right by the trail, and leaves falling in the woods already. Say it ain't so!

Beautiful trail and surprisingly quiet for being in the city.

Friendly trail with multiple wildlife sitings. Well marked and traveled trails. Bugs not bad.

overall it was a pretty easy trail to hike. it's only about 5 miles long and the bugs weren't as bad as others have said. If you're in the area, it's worth a visit, but it's not worth it to travel a long distance to get here.

Getting to this trail is easy from any parking area in the park. If you use the map on the alltrails app, you can easily connect to the trail which is just the trail that circles the outside of the park. This trail is basically a nature walk. No epic views or anything, but consistently pleasant trail with some streams and meadows nearby, and a lot of deer in the forest. It's relatively unused considering how close it is to DC. There are a number of instances where it gets pretty close to the freeway, so for about half the hike, you can hear road noise. There are only a few points where you can visualize the freeway. My only complaint, and it would keep me from coming back in the spring or summer, is the number of ticks. I had at least 5 ticks on me, and the dog had over 10. Whenever we would sit, we could see ticks scurrying up our legs. Pretty gross. Afterwards, there were ticks in the car, and in the gear. A lot of people camp in the area. Apparently they are less weirded out by ticks than I am...

Nice trail with lots of deer sightings. However, there were WAY too many ticks all throughout the trail. If I sat down for 5 min I would find at least one tick on my leg. I brought my dog on the hike and he had a minimum of 10 ticks on him. I highly recommend avoiding this trail during tick season (May - Aug) -- it wasn't at all worth the hassle.

This loop is at least 8-9 miles, not sure why it is describe as around 5 on most tracks shown. All other descriptions are pretty accurate.

There'a few downed trees and some parts where trail maintenance has fallen a little bit, and traffic noise is a factor for decent chunks, but once you get deeper into the trail, it's quite pretty, and not super difficult. Good to get out of the city for a bit and enjoy an afternoon. Was worth the five miles or so.

clearly marked trail with slight inclines at some points. Small streams rock formations on some points of the trails.

It was a fun trail to hike. Clearly marked path.

Very good and well marked out trail. Only 5.4 miles though. Nice for a quick 'get out of the city' trail. Maybe if you add in all the side trails it may be higher. Well marked and managed. There was one part that was washed out but it was easy to adjust. Quite a few deer running about. Moderate amount of traffic. I recommend it for any level.

Nice trail but watch for bugs. I have gotten chiggers 3 times here in the summer!

5.2 mile loop around the perimeter of Greenbelt National Park. (not to be confused with the nearby lake - that's Buddy Attick Park, owned/maintained by City of Greenbelt).
Well maintained and blazed, fairly secluded path with about 400 ft of total elevation change. Good for older kids that can walk 5 miles.
Moment of potential confusion where trail crosses Still Creek and converges with fireroad and a neighborhood access trail. If you use the trail map (available at park office and at most trailheads; also on mapboards near trailheads) you should be OK.
Biggest hazard is lots of ticks. Do a check of yourself, kids and dog before getting into car and again before bedtime to avoid lyme disease.
Easy to access from Capital Beltway in MD, exit 23 South to Rte 193 East to park entrance on the right. I suggest parking at Sweetgum parking area--pick up perimeter trail across Park Central at entrance to the parking area.
No bikes allowed on this trail.

awesome trail to walk. saw a couple of deers, have to walk under a fallen tree hoping it won't fall on me lol.. I used an insect and tick repellant so I was good no tick problems at all!

Trail is well-kept. You're never far from help if you need it, and it's easy to access from a couple of the surrounding properties or inside the park at Holly or Dogwood. It has access points to the other much shorter trails. Don't miss Azalea Trail where you can do the exercise loop which has stations for suggested stretches and exercises like incline sit-ups.

Nice, easy , medium/short hike close to home. Terrain is gradual climbs and descents. You can hear road noise through most of it, but like someone said, the quiet parts are worth it. Marked with yellow blazes.

This is an nice trail in the middle of a busy area. You end up getting a little noise from the nearby highways when you are on the outside edges of the park, but the majority of the trail is quiet. Somehow this trail is listed as a biking trail, but biking is NOT allowed on the trail. Found that out the hard way unfortunately. The trail itself is well defined and marked, but be careful to not wander off to the ancillary trails leading to the campgrounds. Every time we have visited this trail we have encountered very few people. Overall, its a nice choice for an easy hike/walk close to home.

Worse tick experience ever! Wore long pants and still removed more than 10 from my upper leg area. Spray and more spray!!! Other friends have also experienced a high number of ticks. Great area besides the
