So, I haven't been here in quite some time. There's a reason this is a regional park...it's huge! I've been here multiple times either for personal leisure with my kids or during the Christmas light show each year. We only went to the playground but, wow, they did an amazing renovation to the playground. It's like a fairytale-like playground that seems like it needs its own storybook. The colors... So, I haven't been here in quite some time. There's a reason this is a regional park...it's huge! I've been here multiple times either for personal leisure with my kids or during the Christmas light show each year. We only went to the playground but, wow, they did an amazing renovation to the playground. It's like a fairytale-like playground that seems like it needs its own storybook. The colors are so vibrant and beautiful. There are so many gadgets, slides, barnes, houses; trinkets, and much more! There's so much open space, picnic spaces, pavillions; grills, trails, so on, and so forth. Usually, I have to supplement the entertainment for my kids by being an imaginary monster. However, this time around, they didn't even think of asking me they just ran straight to the playground and started engaging with all its wonderful intricacies. Now that I'm aware of this newfound renovation, this park will definitely make the top two list of playgrounds we visit regularly. You gotta check it out, especially if you have kids and need to entertain them. Let me know your thoughts. I can't wait to hear what you have to say.

Saturday, June 14, 2025 – Juneteenth Festival at Watkins Regional Park What an amazing day! We had the pleasure of attending the Juneteenth Festival 2025 at Watkins Regional Park, and the experience was nothing short of incredible. The celebration brought together art, culture, and community in a powerful way. The festival was a vibrant Arts and Heritage Celebration that honored the spirit of Juneteenth with live bands, horseback rides, delicious food vendors, and a variety of fun activities spread throughout the park. From the music to the cultural showcases, it was a day filled with joy, education, and unity. Grateful to be part of such a meaningful event that celebrates freedom, creativity, and heritage. Looking forward to coming back next year!

Good serene environment for all round picnic and special events. It has sheds and lots of natural tree canopy to keep the atmosphere cool.

Wonderful park with loads to do. Worth the trip from DC. The playground was nice and had a lot for kids to do. Probably better for older kids (4+) than toddlers. The nature center was great! Lots of animals and the people working there were so nice. They let the kids feed the fish while they tended to a turtle in the same tank. They didn’t have to do that, so it was very nice. There are also plent... Wonderful park with loads to do. Worth the trip from DC. The playground was nice and had a lot for kids to do. Probably better for older kids (4+) than toddlers. The nature center was great! Lots of animals and the people working there were so nice. They let the kids feed the fish while they tended to a turtle in the same tank. They didn’t have to do that, so it was very nice. There are also plenty of bathrooms all around the grounds which is great with little kids. The trails were well marked and easy to follow. The Farm had a good variety of animals and the signs were very informative. Over all a great morning spent there.

I had only been to the Wizard of Oz playground before with my grandkids. Today I followed the trails around and got all the way over to the farm. That male turkey was seriously showing off for the female, but I'm not sure you can see her in either of the videos. The nature center was very nice. And there are a couple of interesting cultures on the trail also. I believe they called them "chainsaw s... I had only been to the Wizard of Oz playground before with my grandkids.

The trails are all paved and accessible to all.

Large campground with plenty of space and good-sized rustic sites with fire ring and trash/recycling, very affordable! No electric and only one bathhouse on a long loop, so be careful which site you pick or face a little hike on the shaded path or camp loop road. It was very quiet on a hot July weekend, but at least 10 degrees cooler than outside the park, Fall would be lovely. Bring bug spray for... Large campground with plenty of space and good-sized rustic sites with fire ring and trash/recycling, very affordable! No electric and only one bathhouse on a long loop, so be careful which site you pick or face a little hike on the shaded path or camp loop road. It was very quiet on a hot July weekend, but at least 10 degrees cooler than outside the park, Fall would be lovely. Bring bug spray for skeeters, stay up to watch the fireflies dance. Close to many amenities in a residential area and such a cute park with playgrounds and softball and more! Bathhouse was basic but clean, ADA accessible, and in good condition.

Great beginner dry camping locations have a bathhouse and restrooms. Only few camping spots, so reserve in advance.
