Sponsored by BRS Backyard Bug Busters ›Paved tracks, ballfields, playgrounds, and wooded hiking trails tucked into West Milford's Highlands.
Arlington Ave in Hewitt dead-ends into something genuinely worth stopping for. Highlands Preserve sits on the edge of the New Jersey Highlands, and the county has done real work here: a paved loop track for walkers and joggers, well-maintained ballfields, a playground that actually gets used, and marked woodland trails that push deeper into the forest canopy.
The trails themselves are the draw for most visitors. Once you step past the treeline, the ground opens up through a mix of exposed rock outcroppings and quiet forest floor, with stretches that feel miles removed from any parking lot. Dogs love it. The mile-in turnaround point most first-timers hit is honestly just the beginning. Regulars who know the route push further and find sections of open meadow and ridge views that justify the trip every single time.
Rated 4.7 out of 5 across nearly 30 reviews, this is a park that earns its reputation by delivering variety. Whether you're here for a morning lap on the paved track or a genuine woodland hike with the family, the preserve handles both without feeling crowded or cut short.
Highlands Preserve offers a full suite of outdoor recreation anchored by its location along the Wanaque Reservoir watershed corridor. The paved perimeter track is smooth, well-marked, and ideal for strollers, cyclists, and anyone logging daily steps. The ballfields are maintained to a standard that community leagues actually rely on, and the playground area gives younger kids a reason to come back on weekends.
The hiking trail network is the preserve's crown jewel. Marked paths wind through mixed hardwood forest, crossing over rock formations characteristic of the New Jersey Highlands geology. Trail signage has improved significantly with recent county investment, though carrying a downloaded map is still smart for first-time visitors who want to push beyond the first mile. The terrain ranges from easy flat stretches to moderate inclines.
Admission is free and the preserve is open year-round, making it one of West Milford's most accessible green spaces. Pack water, bring the dog on a leash, and plan to stay longer than you think you will.
