Grading on the curve of "it's in Maryland", this is a fantastic trail!…read more If this were west of the rockies though, it would be A-OK. There is one tiny section where you actually have to scramble. The rest of it is pretty much a moderate hike with some lite route-finding. We saw multiple snakes on the way in, which were the highlight. Definitely worth doing if you're in the area, but probably not worth a dedicated trip if you're in DC proper.

Not a reflection of the trail as a whole, but when I stopped back on this occasion I was dismayed…read more It was one thing during the peak of the COVID era when there were signs up saying this trail was to be undertaken in one direction only. People were throwing around all sorts of silly rules out of desperation in those days. I doubt any lives were saved by this; maybe the theory was to reduce human contact but realistically, we're talking about hiking in open air. Public health aside, I return to find even now there are still signs saying to take the trail one way. And having done it both ways many times, it's the wrong way! Absurd. Supposedly there's some justification, but I think that grown adults can figure out how to hike in two directions without running into each other. As an overall natural resource, it remains a gem (though it must be noted that the Billy Goat B trail downstream is currently closed due to damage). But whoever is making these stupid rules shouldn't be in the business of making rules at all. Thankfully some rebels were taking the trail in the northernly direction, as well they should.

The lake itself is gorgeous, and always so picturesque.... I have hiked the Lakeside Trail a few times, which is about three miles and mostly wooded, with two creek crossings (one easy, the other more difficult, requiring stepping on stones that could be slippery or even, at times, underwater). The first time we hiked the trail we did get lost as we skipped the difficult creek crossing and ended up going straight, and almost right back out of park...so bring water to drink and wear (or bring) a pair of shoes that can handle the creek water (it's not safe to swim--so I'm assuming, or wade around--in). UPDATE: Part of the Lakeside Trail has construction going on around it (near the easier stream crossing) and last time we encountered it we decided to turn around rather than trying to get around the mess...but there are other parts of the trail to explore, including hiking along the path that' intersects with Rock Creek Trail (or you can go around the other end of the Lakeside Trail, close to the Avery Park entrance...) Usually when we're here we don't do the entire trail, anyway, but turn around at various points, depending upon how long we want to walk. Although the park does get busy on weekends (and it can be difficult to get a parking spot at the Avery Park lot) the further along the trails you go the less people you'll encounter. Weekdays are also pretty peaceful. I look forward to visiting the Meadowside Nature Center when it reopens--this is located at the other park entrance at Muncaster Mill Road.

But I also start at Carderock for a change or if that is how the race is set up. I don't do much in the park itself. But I see it is a lovely, underused facility (which I don't want to ruin). There is, as people have mentioned, a military facility nearby. I wonder as I drive around, if they are conducting surveillance or if you'd get in trouble for doing something such as taking photographs. I've never had an issue though, if you were wondering. I have gotten lost, however, because it's not quite clear (and GPS is not precise) how you get to where you want to go once you take the exit. I recommend Carderock highly for a hike. I believe it also is a nice place to hang out, even if you don't get to the trail (but why would you go here and not at least take a gander at the water).

First, the park includes waterfalls, pine trees, granite cliffs, and babbling brooks. Second, the Visitor's Center area has restrooms, staff who can answer questions, and a simple "old-school" ice cream and snack shop. Third, the river trail and waterfall outlooks provide amazing scenery without much effort - just a bit of walking. What more can you ask for? It's $20 per vehicle (for 7 days of use), or if you have an annual national park pass ($80), it's valid here. On the last Saturday of May 2026, it was crowded but parking was still available in the additional parking lot (second one past the visitor center) around 11:50am.

Great Falls & National Parks, Oh my!! (US National Parks) worth an Annual Pass…read more Do you like easy walking trails? Beautiful views? A front seat to nature...ducks, frogs eagles and other animals await your visit to Great Falls Park. It's really 2 parks in 1, or is that 1 park cut into 2? Let me explain, Great Falls is a national park that sits in the border of Maryland and Virginia. The trails were relatively easy, in regular sneakers. Apparently, if you get up in the morning you can see an amazing array of wildlife and a huge amount of birds. There's even a man made waterfall, areas to enjoy water sports and fishing. It cost $20 per car, $15 per motorcycle and $10 on foot. It cost $35 for Annual Pass (only for Great Falls Park and C&O Canal National Historical Park). There's also an America the Beautiful--the National Parks and Federal Recreational Lands Pass, which cost $80 for US residents and citizens. For nonresident it cost $250. There are even a senior citizen resident annual pass for $20 and lifetime resident pass $80. For the cost of a one year annual pass, you can visit many times in a year. It's cheaper than paying each time you go...if you are into physical fitness, trails, nature and the great outdoors. Did you know the US National Parks include a rainforest and a Spanish Fort located in Puerto Rico, a US territory. Yes, for such a small area Washington, DC has 30 National Parks (including historic sites, memorials, and parkways). But wait there's more, The Greater Capital Region (DC, MD and DC) has 86 Parks in total with all parks and sites maintained by the US Parks Department. Are you going to Great Falls or will you hit all the US Parks this summer? Get a pass and get out in nature.
