Thompson Park - Middlesex County

Easy wooded trails with rolling hills and a meandering stream.

2.4 miles. Easy, dirt with roots.

Note: There are also trails south of this section, below Schoolhouse Road, called “Thompson Park Conservation Area” (…and the sections now all connect which allows for loops up to around 8-ish miles).

Not to be confused with the Thompson Park in Monmouth County.

Our two cents:

Really nice short trail plus the option to continue on into the conservation area to up the mileage.

In addition to an off-leash dog park near the trailhead, the main area of Thompson Park contains a lake, a small zoo, playground, and picnic areas.

Usually nice large printed maps in the trail kiosk or print ahead in case.


None that we know of.

This trailhead is next to the dog run area (Perrineville Road to Fir Drive), near the trail kiosk.


A restroom building is near the dog run parking lot.

Longer Variation
: Turn right and start following GREEN instead, cross a wooden plank bridge.

When we hiked this in summer, there were tons of butterflies in the bushes on either side of the plank boardwalk a few steps down on GREEN.


Turn right on GREEN, keep right at the split to start on WHITE, which ends at a parking lot by Manalapan Lake, and then take the dirt park road back to the lot]

Continue on YELLOW. Soon, turn RIGHT to start following ORANGE over a small bridge [YELLOW continues left].

After the bridge, turn LEFT and continue on ORANGE [ORANGE also goes straight, and an unmarked trail goes right].

Pass RED on the left, continuing on ORANGE to return to the lot.
