This park is not far from the headwaters of Rock Creek, and is a nice quite oasis in the middle of Derwood, MD. Located between Rockville and Gaithersburg in Rock Creek Park, it is nice place to hike, have a picnic, go fishing, in the summer go paddle boating or canoeing. For picnicing you can rent a pavilion near one of the playgrounds. They also have an archery range. You can download maps of the park that show the hiking trails. This a great place to bring the family for a fun day.
