Search "Hemlock Falls" on any map app and you will land in nearly the same spot every time: the Tulip Springs lot off South Orange Avenue, or the smaller overflow lot near the Pine Grove Bridge a few minutes down the road. That is the West Orange side of South Mountain Reservation, and many trail guides describe routes to the reservation's best-known waterfall from this side.
Some visitors have mentioned crowding there. One recent Tripadvisor review of the park put it plainly: "Beautiful park, trails, and reservation, but far too crowded for my tastes." A New Jersey Monthly writer who followed an app-recommended route to the falls last October described getting turned around more than once near the trail junctions. The short loop from Tulip Springs to Hemlock Falls, at 1.7 miles and roughly 45 minutes round trip, is the reservation's most-reviewed hike, and visitor reviews include comments about crowding.
Millburn residents also have an entrance to the reservation at Locust Grove.
The Locust Grove Entrance in Millburn
At the bottom of Glen Avenue, across from Lackawanna Place and around the corner from the Millburn Free Public Library, a small sign reading "Locust Grove" marks a driveway into South Mountain Reservation from the Millburn side. The parking lot there sits about a hundred yards from the Millburn train station, close enough that a resident stepping off a Midtown Direct train could walk straight into the reservation without ever getting in a car. The lot fills on busy weekends, and overflow parking is on a residential block.
From Locust Grove, the route to Hemlock Falls is longer. AllTrails lists it as a 6.1-mile loop with 813 feet of elevation gain, taking two and a half to three hours, compared to the 45-minute version from the West Orange side. The routes offer different experiences: a longer hike from Millburn and a shorter walk from the West Orange side.

| Time | 2.5–3 hours | 30–60 minutes |
| Elevation gain | 813 feet | 298 feet |

What the Longer Route Actually Passes
The Locust Grove loop is not just a longer way to the same view. It strings together most of the reservation's namable landmarks in one walk. Heading out on the yellow-blazed Lenape Trail, hikers cross Maple Brook at the cascades locals call Maple Falls, then Beech Brook a bit further on, both minor but genuinely pretty water features that the short Tulip Springs loop skips entirely. Around the 2.6-mile mark the trail reaches Ball's Bluff, where a pair of stone pillars, all that remains of a picnic pavilion built in 1908, mark a lookout over Millburn toward the Watchung Reservation. The falls themselves come into view a half mile later, followed almost immediately by the smaller Hobble Falls, easy to miss if there has not been much rain.
The Lenape Trail itself is worth knowing by name. It is a 36-mile trail that Essex County's park system built to connect 18 parks across 11 municipalities, and the section running through South Mountain Reservation is one continuous piece of a much longer network. A Millburn resident who starts at Locust Grove and follows the yellow blazes far enough is, technically, on the same trail that eventually threads through Maplewood, South Orange, and West Orange without a single road crossing needed to get there.
Comparing the West Orange and Millburn Entrances
None of this makes the Tulip Springs entrance a bad choice. It is simply the default one, because it is closer to the falls and it is what shows up first in a search. The reservation itself covers 2,112 acres across Millburn, Maplewood, and West Orange, and its layout was finalized by the Olmsted Brothers after Frederick Law Olmsted personally scouted the land in the 1890s, with much of the trail and bridge infrastructure built decades later by Civilian Conservation Corps crews in the 1930s. It was designed as one connected landscape, not two separate parks, with access points in Millburn as well as West Orange.
Each entrance offers a different route to the falls.
What Changes This Time of Year
Fall adds a few practical wrinkles worth knowing before heading out from either entrance. The Rahway River section of the Locust Grove loop is one of the better spots in the reservation for foliage, since the trail runs alongside the water for a stretch rather than just crossing it. Waterfall flow at Hemlock Falls depends heavily on recent rain, so a dry September stretch means a quieter trickle, while a wet week turns it into the version most photos show. A hiking guide last updated this spring flags several low sections along the Lenape Trail near the falls as reliably muddy after heavy rain, with stepping stones in some spots and plain mud in others, so trail runners in particular should plan footwear accordingly. Dogs are welcome throughout the reservation on leash.
Where to Find a Trail Map
Given how often hikers report losing the trail near the falls junction, it is worth grabbing a physical map before heading out rather than relying on a phone. The South Mountain Conservancy sells a waterproof trail map that residents can also find locally at Words Bookstore and at the Millburn Free Public Library, along with a companion trail guide booklet that describes each named route individually. For a resident starting from Locust Grove, a paper map and trail guide provide route information for the walk.
The Backyard Most Residents Are Only Half Using
South Mountain Reservation sits inside the daily radius of anyone living in Millburn or Short Hills, but most of what gets written about it describes a park accessed from somewhere else. The version reachable on foot from the Millburn train station rarely makes the list, even though it reaches the same waterfall, passes more of the reservation's actual landmarks along the way, and does not require parking in West Orange.
Knowing which door to use does not require expertise. It requires knowing that the reservation has more than one, and that the Locust Grove entrance is closest to home.
