Length: 3-mile loop
Time: 2 hours
Difficulty: ★★☆☆☆
The Blue Trail at Morristown National Historical Park gets its name from the color coding (blue) on the trail map. However, it is actually comprised of the New York Brigade Trail, the Inner Loop Trail, the Outer Loop Trail, and the Old Camp Road Trail, all of which are open to hikers and horseback riders. The hike I am describing in this review, a 3-mile loop, starts on Jockey Hollow Road by following the New York Brigade Trail southeast. It bypasses the Inner Loop Trail and continues until connecting to the Outer Loop Trail, which then curves southwest to connect with the Old Camp Road Trail via a .1-mile section of the Inner Loop Trail. The Old Camp Road Trail then heads northwest back to Jockey Hollow Road. If you want a shorter hike, take the Inner Loop Trail over to the Old Camp Road Trail. This shortcut knocks a mile off the hike.
The trailhead for the New York Brigade Trail is at the first parking lot on Jockey Hollow Road after entering the Jockey Hollow Encampment Area. This is the general area of where the New York Brigade set up camp for the winter of 1779-80. In addition to parking, there is a restroom facility.

The hike starts behind the restroom building, and from there the trail heads downhill on a gradual slope for a quarter mile towards a small creek called Primrose Brook. At the creek it intersects and temporarily merges for a short distance with the White Trail (aka the Grand Loop Trail). The directional sign at the intersection is not very clear about which way to turn, but if you look closely, you will see a tree on which two blue squares that stair-step to the left have been painted. These paint splotches are known as blazes, and they serve as Hansel and Gretel breadcrumbs for hikers to follow. A double blaze indicates a turn; a stair-step to the left indicates a left turn. And of course blue paint marks the route of the Blue Trail.

Before coming to where the Blue and White trails diverge, there is a small pond with a bench along the shore. This is Cat Swamp Pond, and Primrose Brook supplies the water, but I am not sure if this is done by a natural or man-made dam.
The trails split just a couple of minutes past the pond. To remain on the Blue Trail, stay to the right. Soon thereafter, the trail crosses Primrose Brook and begins climbing uphill, then splits again just a few minutes later. The fork to the left is an unnamed trail that leads to the park boundary. The trail map shows this as a solid, brownish line. Stay straight to remain on the Blue Trail.

The intersection with the Inner Loop Trail comes about .75 mile from the parking lot. As mentioned earlier, if you want to cut the hike short, take a sharp right at this intersection to head over to Old Camp Road Trail, otherwise continue straight towards the Outer Loop Trail, which is where I was heading.

There is one last intersection with another trail that leads to the park boundary before the Blue Trail begins to curve around to the south on the Outer Loop Trail. There are houses in this area, so I am guessing this provides trail access for the local residents. Take a right just past the gate to continue the hike.

The Outer Loop Trail portion of the Blue Trail starts off as a gravel path but quickly becomes a dirt road. From the tire tracks, it appears that park Rangers drive on the trail, which is why a gate was at the entrance.

At the 1.25-mile mark on the hike—a quarter mile from the turn at the gated intersection—is a wayside exhibit and monument marking the slope where a brigade of New England troops under the command of John Stark camped during the winter of 1779-80.
After a few thousand men died at Valley Forge in the winter of 1777-78 partially due to camping in low-lying terrain that was subject to poor drainage, General George Washington’s Continental Army learned to build camps on the slopes and tops of hills. This is why the Stark’s Brigade made its camp on the slopes of Mount Kemble, a small mountain the Inner and Outer Loop trails circle around. The trails do not climb to the summit, but they do rise high enough to provide a view of the valley where houses of suburban Morristown are situated.

Less that .2 mile past the Stark’s Brigade marker is a turnoff for Old Camp Road Trail. Old Camp Road was cut by soldiers during the American Revolution to connect Jockey Hollow Road to Basking Ridge Road, which no longer exists as far as I know. While the hike along the Blue Trail eventually ends up on Old Camp Road Trail, it makes this connection a quarter mile farther down, so skip this turn and continue straight.

As the Blue Trail makes its way to its western intersection with the Inner Loop Trail, the surface gets a little rocky, and the trail begins to gradually slope downhill. Some of the rocks are loose, and stepping on them is like stepping on marbles, so be careful.

At the intersection with the Inner Loop Trail, take a left towards Old Camp Road Trail as directed by the posted sign. It is only .1 mile to the intersection. Once there, take a right to head back to Jockey Hollow Road. Both turns are so sharp that they are essentially U-turns.

On the way to Jockey Hollow Road, the Blue Trail once again merges with the White Trail. At the first intersection, the White Trail dead ends into the Blue Trail from the left, and a hundred yards or so farther down, just after crossing Primrose Brook for a second time, the White Trail splits off to the right. Stay straight at each intersection to remain on the Blue Trail.
When the Blue Trail finally reaches Jockey Hollow Road, it crosses over and continues on the other side. No horses are allowed on this section because the trail becomes much narrower than it has been previously. It parallels the road all the way to the New York Brigade Trail parking lot, so you do have the option to walk back on the pavement if you prefer.
If you do take the trail, shortly after crossing Jockey Hollow Road is an intersection with the Yellow Trail that is marked by a small footbridge that spans a narrow stream. To remain on the Blue Trail, turn right before the bridge—do not cross the stream.

The final quarter-mile stretch of the trail has a surface full of rocks and roots. It also heads up a moderately steep hill. While certainly not a deterrent to anyone who set out to hike a 3-mile trail to begin with, this is undoubtedly the toughest section of the journey.

When I am hiking a trail in a history-themed park such as Morristown National Historical Park, I want to hike a trail that takes me past historical sites so I can get a feel for the events that took place. Despite the fact that the Blue Trail starts off at the New York Brigade encampment site and passes the Stark’s Brigade monument—which can only be reached on foot—it simply isn’t all that interesting. Its width makes it a great social trail since you can walk side-by-side with a friend, but ultimately it’s just a walk through the forest, and one monument doesn’t make up for its shortcomings. I suggest spending your time elsewhere unless you are just out for exercise, and even then I’d recommend the much longer White Trail if that’s what you are after.
