Hartshorne Woods Park

Updated:
Trail marker post for the Laurel and Grand Loop trails.

Hike through mountain laurel over rolling hills, enjoy river and ocean views, and check out military bunkers from WWII.

8.9 miles. Packed dirt with roots, a minor amount of rocks. Decent amount of rolling hills but nothing real steep. The trails are multi-use and this is a popular mountain biking spot.

8.9 milesThis hike guide: Detailed instructions, photos, and video follow below.
ShorterLarge trail network allows for many bail-out points; several noted in the description below; or do an individual loop from this lot:
0.7 – Kings Hollow
1.5 – Candlestick
2.5 – Laurel Ridge
LongerRoute could be extended by hiking through Grand Tour and Laurel Valley trails again instead of returning via Cuestra Ridge.
Alternate, shorter:Start from the Rocky Point lot instead and do Rocky Point Loop or just the trails around Battery Lewis and Black Fish Cove.

Our two cents: 

This loop is better for avid hikers wanting to see the whole park.

Casual hikers might want to do a short loop from here or start from the Rocky Point lot and loop to Black Fish Cove and Battery Lewis which packs all the big scenic items into a shorter hike.

There is now a Very Big Gun in Battery Lewis with interpretive panels about the role this area played in WWII, as well as how the gun was obtained and moved. The park’s web site has info too.

Updated: 12/2023 – Minor edits, re-hiked slightly shorter version. Older change log at page bottom.

No-hunting: Except closed on certain dates in Dec./Jan – check park site.


Map:

Paper maps are usually in the trail kiosks around the park, or print out ahead. Follow along on your smartphone with our Interactive Map link above.

Books:

Very similar route is now in Best Day Hikes in New Jersey. A similar but shorter (7.0 m) route can be found in 60 Hikes Within 60 Miles: New York City. A 2.7 mile loop is in 50 Hikes in New Jersey. The park trails are described in the The New Jersey Walk Book.

Hike Directions:

Overview: Laurel Ridge – Grand Tour – Rocky Point – Battery Loop – Cuestra Ridge – Laurel Ridge

We have done our best to describe the route below, but trails are not blazed with colors and instead have signposts at junctions so it can get confusing.

Please have the trail map with you. Our Hartshorne Interactive Map can help track your location along this route.

The trail map uses circles, squares, and diamonds to show biking difficulty only. None of the trails here are ‘difficult’ for hikers.

0.0 – From the Buttermilk Valley parking lot, start following the Laurel Ridge Trail. It is on the right, near the portable toilet.

Laurel Ridge Trail.

0.5 – Pass an unmarked path on the right which leads to Hartshorne Rd. and another parking area called Claypit Creek.

Laurel Ridge Trail.

1.0 – Turn RIGHT and follow a long side trail to an overlook. It ends at a small loop with a limited view. Retrace your steps to this point and turn RIGHT back on to Laurel Ridge.

The view is quite limited, especially with leaves on the trees, so this is skippable (removes 0.3 miles total).

Approaching the limited overlook on Laurel Ridge.

Continue following Laurel Ridge.

2.3 – Turn RIGHT to now follow Grand Tour. [Laurel Ridge continues and leads back to the lot.]

Marker post at the intersection of Laurel and Grand Loop trails.

2.7 – Bear LEFT as the trail splits. The right leads to a cabin and maintenance area.

3.1 – Turn RIGHT at a T-intersection to continue following Grand Tour.

// Shorter: Left leads to the Cuestra Ridge trail and back to the lot if you’ve had enough. //

3.4 – Grand Tour curves to the LEFT. [Pass a sign post for Hartshorne Road on the right.]

3.6 – Turn RIGHT to continue on Grand Tour. To the right is a “connector” post while ahead is a “trailhead” post (and a trail not on the map).

3.8 – Arrive at the Command Loop intersection with two stone pillars on the right.

Command Loop stone marker to the right.

Cross the road and veer LEFT now follow Rocky Point trail (not straight ahead on the paved path).

[Right is the Command Loop road that just leads to a small bit of foundation and piles of dirt so it’s not included here but is an optional add-on.]

// Shorter: Sharp left leads to Cuestra Ridge and a shorter route back. Left is the park road that leads directly to the Rocky Point lot and Battery Lewis. //

4.0 – Bunker Loop junction. Turn RIGHT and follow the paved path around, looping back to this point.

Paved Bunker Loop trail.

The cement entrance to the bunker is visible under a huge mound of dirt.

Peek through the fence to see a little inside.

Continue around the paved loop to where you started. Turn RIGHT to continue on the Rocky Point trail.

4.7 – Turn RIGHT to out-and-back on a short side trail to an limited view over the Navesink River.

Overlook off of Rocky Point trail.

Shortly, the trail splits at a steep section and then rejoins.

5.4 – Turn RIGHT onto the paved path to head towards Black Fish Cove pier, with a picnic table and porta-john.

Return via the paved path. Turn RIGHT, continuing on Rocky Point. There are a couple of unmarked trails here, so it’s a little unclear… basically keep bearing right toward the water and not inland.

6.0 – Turn RIGHT onto the paved path and walk a short ways down to a grassy area with picnic table. 

There is a limited view over the Shrewsbury River to houses on Sea Bright from this area.

Retrace your steps on the paved path. [Pass Rocky Point on the right and will skip the Battery Loop]

Continue straight on the paved path as it goes up to an overlook on the left.

6.3 – Overlook over the Shrewsbury River, houses, to the ocean.

Turn around and head towards Battery Lewis on a dirt path. There is also a paved path (Battery Loop on the map) on the right that leads to the bunkers as well.

Walking towards the gun batteries.

6.7 – Arrive at a paved path t-intersection, with a bunker to the left and right.

Big Gun in Battery Lewis.

Explore the bunkers, the Big Gun, and interpretive signage.

You can wander around however you like… but we went into the left bunker with the gun first.

Then to the right bunker.

Next we took the path to the top of the bunkers for more views.

View from the top of Battery Lewis.

We walked across the top of the bunkers then down a path over the right one to the paved trail, but you can also walk through an open bunker to get to the paved path.

However you go, turn RIGHT onto the paved path and walk toward the Rocky Point parking lot. [There may be a porta-john/bathroom in the lot].

7.2 – Arrive at a T with another paved path, with the parking lot immediately on the left. Depending on how much you walked around the bunkers, your mileage may vary.

Turn LEFT onto the path and walk toward stone pillars with a sign “Authorized Vehicle Only”.

Continue down the paved road.

7.3 – Turn RIGHT onto the Cuestra Ridge Trail at a post with “Buttermilk Lot” also. This is an easy, mostly level woods road.

Follow Cuestra Ridge, ignoring two intersections with Grand Loop. Cuestra Ridge becomes Laurel Ridge and leads back to the parking lot.

Cuesta Ridge trail is a wide flat path.
