Mill has undergone a fresh $3 million renovation. 4 floors of history. Museum guide gave a helpful (and free) talk about how the mill worked. Take a step back in history to explore this gem. A visit takes as little as 10 minutes. You can also learn more about Rock creek there as well.

Great place to sit outside and read. Parking nearby, space for kids.to run,.a few.picnic.tables. Restrooms presently closed.for repair.

Nice little spot just outside of downtown DC. Good access to rock creek park, right on the water. Has bathrooms and water as well as an open grassy area and picnic benches. Very small parking area but can park further up along the road. All in all decent place to enjoy the outdoors

Lovely and lively! Beautiful walks next to the stream, picnic tables, and the mill itself has interesting history.

So happy I made the stopover here. Great piece of American history. Well maintained and at a great location.

A nice place for walking and running with different trails and a picnic area.

A fascinating and beautiful place to visit with a lot of history to learn. There is a lovely trail and stream with the dam waterfall. Theres the mil house and the barn very close together. A great pitstop...also recommended is the Hillwood mansion nearby.

This is a super cool place to visit. During the summer months they have showings of how the mill works. Everyone is super friendly and willing to tell you about the fascinating history this place has.

Beautiful place that seems to take you back in time. I was hoping to take a tour of the inside but it was closed. Although i was disappointed I got to sit down and watch the stream and enjoy the moment. There are also some informational boards that give you historical facts. There is a parking lot right across the mill and its conveniently close to the national zoo. I parked my car at this parking lot for free and walked to the zoo.

I nerded out way too much here. Well-preserved (and in some areas restored) mill house complete with diagrams and equipment to illustrate their process. Great learning experience for all regardless of age and, naturally, right by the water :)

A Nice and great historic spot in Rock Greek Park! The ranger and volunteer were so welcoming and knowledgeable!

Nice park, peaceful.

Fascinating place. Will revisit in the summer to see the wheel in operation.

Awesome history in DC!

Its not that there is much to see but the old mill is very well preserved and worth a visit.

In a city full of amazing public spaces to spend a picnic lunch or dinner, this might be at the top.

Pierce Mill and the surrounding trials are a joy.

Fun morning.

You can bring your grill and have a nice Sunday afternoon here.

Neat place to walk around and see some historical items up close. Also could be a nice spot for a field trip.

Charming, historic mill in the middle of Rock Creek Park. Easy access to a number of hiking/running trails. There is a small parking lot, bathrooms, and a picnic area. One of my favorite places in Rock Creek Park.

I did my maternity pictures here. It’s a beautiful place. Just very little parking. Great for photos and picnics.

Enjoying this beautiful park.!!

Looked cool as heck but was closed when I was there.

Fun. Friendly. Interesting. Historic.

The staff is incredibly helpful and friendly, the premises are dog friendly, and the building itself is kinda neat.We were actually waved down and invited into the building by a park ranger who wanted to pet our dog. Once we got inside we were invited to cool down in front of a large fan, play checkers, and talk about local DC politics. I cannot say enough nice things about the rangers who were there and I wish I could recall their names, they deserve praise. They were knowledgeable about the area but didnt force a message down your throat if you didnt want to talk about a mill.Personally, I didnt find the mill that interesting, but the staff really made it worth a trip. Looking forward to stopping by next time Im walking along Rock Creek.

A hidden gem if you want to add a unique stop to a day in Rock Creek Park. The park rangers and volunteers are welcoming and knowledgable, and theres plenty of posters, books, and photos to help visitors learn about the interesting history of the building. Check their website for occasional special events including a bi-monthly running of the mill. Bonus: its dog-friendly!

Beautiful little park, lots of trees, a walking path, very peaceful.

Nice and interesting place, well kept by volunteers which twice a month makes the mill work for real. Very nice for kids! Tables outside for picnics

Great way to spend the day.

Grow up living there its home.

Adorable, historic, authentic mill in the heart of Rock Creek Park. This is one on my favorite places to park to hike and run on the trails.

Last mill on Rock Creek wort a visit to see how flour was made back in the day

Beautiful area...has paths and a trail for running, walking; picnic tables, bathrooms.

Learn the history of Peirce Mill.

Great place to get away in the city. Check out the mill, its like a tiny field trip.

A great place to meet up with a running group. There are several trails to follow from this starting point, from easy walking and biking trails to more rugged trail running. Theres also a decent amount of parking spaces and an open lawn for picnicking as well as activities like frisbee or ball tosses.

A great historic building to visit and enjoy in rock creek park

A Real working Pre Civil War -- Flower Mill ... powered by a Water Wheel and large Mill Stones..Run by the Rock Creek National Park Service...Beautiful Park.

Excellent historical reference

Great place for your bathroom break. Always clean!

Tour guides were excellent and knowledgeable. Great spot to picnic nearby afterwards!

Pleasant park and picnic area.

Great parking lot not too crowded during the week. Crowded on weekends. Nice bathrooms. Good soap to wash your hands.

Great little piece of history.

Favorite landmark in Rock Creek Park...

Great place to relax from city life. Easy access to WO&D Trail.

Absolutely spectacular park to hike even better to have a cook out be it romantic and or family gathering

A slice of nature and peace during the shut down

Some fascinating info for the history buffs and the gentle waterfall near adds tranquility to the setting

Fun square dance and Ive heard they have amazing family programs!!!!!

Yep ! Check it out.

The Park Service have done a great job of keeping the mill working, and in providing a real sense of the fact that a major farm was run here, in what is now the heart of the city

Fascinating. Great volunteer guide. Wish wed gone on a day when the wheel was turning.

This is a hidden gem, specially if you like engineering. Park Rangers will tell you all about this ingenious mill and how its design was innovative. Come every 2nd and 4th Saturdays to see it in real operation.

Cool little water fall and a great picture spot
