Grand Tour Trail/Laurel Trail Loop
This loop hike traverses remote sections of this park, passing the highest point in Monmouth County and a viewpoint over the Navesink River.
Parking
Take the Garden State Parkway south to Exit 117. Bear left beyond the toll booths and continue on NJ 36 for 11.5 miles. After passing through Atlantic Highlands, turn right at the exit for Red Bank Scenic Road, then turn right at the stop sign onto Navesink Avenue. Continue for 0.3 mile to the Buttermilk Valley parking area for Hartshorne Woods Park, on the left side of the road. (Do not turn right at the intersection of Memorial Drive and Navesink Avenue in Atlantic Highlands.)
Most trails in this park (including the two that make up this hike) are open to joggers, bicyclists and equestrians. Although park regulations provide that bicyclists must yield to all other trail users, hikers should be alert for approaching bicycles on narrow trails. Hikers must yield to equestrians.
From the parking area, proceed ahead to a large trail map posted on a kiosk and turn left onto a wide gravel road that proceeds north, parallel to Navesink Avenue. The road soon curves to the right and ascends gradually through an oak forest, with some mountain laurel. Reaching the crest of the hill, it descends to a junction, marked by signposts, in about half a mile. Here, you should turn left onto the Grand Tour Trail, which follows a narrower gravel road. (A signpost designates this trail with a black diamond, indicating that it is rated as "challenging"; however, the rating system is designed primarily with bicyclists in mind. For hikers, the trail is of no more than moderate difficulty.)
Soon, the trail bears right at a split-rail fence. It ascends gradually on a winding, eroded footpath through mountain laurel thickets, and crosses a crushed-stone service road. Near the top of the hill, it again crosses the road. The elevation at this junction, 268 feet above sea level, is the highest on the trail. Just to the left - at the southwest corner of the fence that surrounds a water tower - is the highest point in Monmouth County, 274 feet above sea level.
Follow the Grand Tour Trail as it descends on a gravel road, soon crossing the Cuesta Ridge Trail, which follows a wider gravel road (there is no signpost at this intersection). The Grand Tour Trail continues to descend gradually (with one rather steep section) until it reaches a junction where the gravel road curves to the right. Continue straight ahead as the trail narrows to a footpath and enters the remote Monmouth Hills section of the park.
The winding trail passes through stands of holly, goes under a power line, and continues through an area with tangled vines. After curving to the right, the trail reaches a junction marked by a signpost. Here, a side trail leaves to the left, but you should continue ahead, following signs to the "trailhead." The trail passes some more holly trees and tangled vines and soon reaches another junction marked with a signpost (this junction is not shown on the park map). Here, the trail turns right and soon again crosses under the power line.
About two miles from the start, the trail arrives at a junction, marked by a post for a map (at this writing, the map is missing). Here, you should turn left and proceed uphill past several huge trees, then continue to ascend on a winding path to the crest of a hill. The trail now begins to descend, passing a wooden cabin on the left, and reaches another intersection. This is the lowest point on the trail, 40 feet above sea level. Here, the trail turns right on a gravel road, passing houses to the left. Soon, the gravel road curves to the right, but you should continue straight ahead on a footpath, passing through mountain laurel thickets.
In another quarter of a mile, to the left of the trail, watch carefully for a tulip tree that appears to be growing out of a horizontal log. The most likely explanation of this unusual feature is that the tree was blown over when young, but its roots remained intact and an upward-pointing branch continued growing as the new trunk. About 300 feet beyond, the trail passes a split-log fence to the right, and it climbs to reach a junction with the Laurel Ridge Trail. Here you should turn left and follow the Laurel Ridge Trail, which proceeds along the side of a hill, with views through the trees of the ridge to the east. It continues through mountain laurel thickets, then passes holly trees and tangled vines.
After about three-quarters of a mile, the trail curves sharply to the right and begins to ascend, now heading northward. Leveling off on the crest of the ridge, it reaches a junction (marked by a signpost) where a side trail to the left leads to the Claypit Creek Overlook. Follow this side trail to the overlook by a split-rail fence. When there are no leaves on the trees, Claypit Creek, the Navesink River, the Oceanic Bridge and the Rumson Peninsula are visible to the southeast.
After enjoying the view, return to the main trail and turn left. The Laurel Ridge Trail now begins to descend, first on a broad switchback, then through mountain laurel thickets, until it reaches a Y -intersection, with paved Hartshorne Road directly ahead. Here, you should take the right fork and follow the trail as it heads north. After descending rather steeply, you'll return to the trail sign at the Buttermilk Valley parking area, where the hike began.
