Volunteers at the visitors center are well versed in the environmental efforts underway there by the usfws. The trails unfortunately are not well marked. The outside is overgrown. However, the inside has many exhibits for child activities and learning to include butterfly gestation stages. They even have a gift shop along with very upscale native animal exhibits.

We enjoyed walking the trails at this park. Somewhat dull colors in late November, but I'm sure it's really nice in the Spring and Fall. Well maintained.

Really nice place to hike around. Quiet and varied surfaces. Very pretty lake area with blooming lily pads and floating bridges. Great trail for dogs. Safe and cool in the summer. Easy parking. Eager for visitor center to reopen.

On our way to a flight overseas at BWI. We found this after lunch and enjoyed walking in the woods and by a lake before spending hours on a flight. Nice paths,well maintained.

The Patuxent Research Refuge has peaceful, easy trails where you can enjoy the lake, woods, and birdwatching. My husband, our dog, and I had a lovely time. The visitor center is nice, with exhibits about nature and a small book store. You can also go fishing. Admission is free. We hope to get back and check out the northern part of the refuge another day.
