Gambrill State Park is a beautiful mountain park, located on the ridge of the Catoctin Mountains in Frederick County. The park has two areas for family activities, the Rock Run area and the High Knob area. The Rock Run area has a campground, a picnic area, and a small pond. The High Knob area has a picnic area, three stone overlooks, three picnic shelters, and a large stone lodge, called the Tea Room. The overlooks provide breath-taking views of the Frederick and Middletown valleys. The picnic shelters and the Tea Room can be rented for special events. The park also has 16 miles of trails for hiking, mountain biking, and horseback riding.
Well maintained trail that has enough elevation changes to give you a good workout but nothing that can't be completed for anyone in fair shape. You can hike just the lower trail or add in the upper trail for an extra 2.5 miles. Today was extremely foggy but there are a couple of overlooks (of what I couldn't tell). Total numbers of miles: 8.0 but I added in a little bit of the Catoctin Trail (blue blazes)
I hiked both the lower and upper yellow trails. Other than North Frederick Overlook, there are no vistas on the yellow trails. In order to get a good view, one should leave the lower yellow trail and enter the High Knob Visitor Center area, rejoin the lower yellow trail afterward.
Hiked this trail with kids - 12 & 7 with a 2 year old on my back. It was great hike. A word of caution though - cross the street when you are in the parking lot and get on the trail there. The trailhead from the parking lot leads to a long, uphill climb and is SOO much easier going the other way. I was thankful for the AllTrails app because it clued me into this and we went the easier way!
