A beautiful national park! If you want a gorgeous view, leisurely walk, or moderate hike then you can find that here. Parking is $20 per vehicle and there's often a line to get in so arrive early and carpool if you can. Check out the NPS website to learn more.
This is a great nature preserve with fun trails and a rewarding waterfall view at the end! It's free to enter, but there are only two small parking lots so you have to get lucky with parking. Compared to Great Falls, it's smaller with less amenities, but also less crowded.
For those who want to eat, drink, and shop! Leesburg Historic District has lots of hidden gems. Get coffee or brunch from cafes like SideBar, Shoe's Cup and Cork, or Cowbell Kitchen and then walk it off by browsing boutiques like Muz & Rose or Wldwst.
