Gambrill State Park

The Yellow Poplar Trail Loop offers a deep dive into the tranquil, dense forests of Gambrill State Park, providing a peaceful escape from more crowded trails. You'll wind through varied terrain, encountering sections carpeted with vibrant yellow-green bracken ferns and, in late spring, blooming mountain laurel. While not boasting grand vistas, the route's charm lies in its remote feel and the immersive experience of hiking through quiet, natural woodlands, making it a favorite for those seeking solitude.

To start your hike, head to the parking area at the High Knob Nature Center, which serves as the primary trailhead for this route. The trail is open to hikers, mountain bikers, and horseback riders, so be mindful of shared use. Given its length and moderate difficulty, starting earlier in the day is advisable to allow ample time, especially if you plan to explore the nearby North Frederick Overlook.

This 6.8-mile (10.9 km) moderate loop, with 804 feet (245 metres) of elevation gain, takes approximately 3 hours and 6 minutes to complete, making it the longest trail in Gambrill State Park. It traverses Catoctin Mountain, the easternmost ridge of the Appalachian Mountains in Maryland, offering a unique geological context. The trail's quiet nature, even on busy days, sets it apart as a prime option for a longer, reflective forest hike.

This loop in Gambrill State Park offers a classic woodland hiking experience, winding through a mature hardwood forest before opening up to expansive views. The trail leads you to the North Frederick Overlook, a significant highlight that provides panoramic vistas over the eastern ridgeline of Catoctin Mountain and towards Frederick city. Expect varied terrain, including rocky sections and some steep hills, which add to the moderate challenge of this 4.6-mile (7.4 km) route.

Planning your visit is straightforward; the park is well-maintained and popular for day trips. While the North Frederick Overlook is car-accessible, this hike provides a more engaging way to experience the park's beauty. Consider starting early or late in the day to catch sunrise or sunset views from the overlook, which are particularly stunning. The park also features picnic areas, making it a great spot to relax after your 2-hour and 6-minute adventure.

Gambrill State Park, located on Catoctin Mountain, boasts over 16 miles of trails, with this particular route offering a good balance of effort and reward. The North Frederick Overlook itself is a piece of history, one of three native-stone overlooks built by the Civilian Conservation Corps in the 1930s. This trail is a solid choice for those seeking a moderate outing with a rewarding viewpoint, showcasing the natural features of Gambrill State Park hiking.
