The Manasquan Reservoir is a source of water for municipalities and utilities, as well as a 1,204-acre (4.87 km2) park, located in Howell Township, in Monmouth County, New Jersey, United States.

The reservoir itself, which is dammed from the Manasquan River, is operated by the New Jersey Water Supply Authority, which is a part of the much larger Raritan Basin Watershed.

[10] The trail is signed with blue-colored metal posts and is marked with brown-colored wooden mileposts.

The mile posts run in a clockwise direction (as the viewer looks north), and start at the southern portion of the park.

Moving northeasterly long Georgia Tavern Road, the trail leads to Chestnut Point where parking is available for nearby recreational fishing.

Past milepost 3 (and roughly around mile 3.3) the trail crosses the main utility service road of the Manasquan Water Supply System, after which it makes a sharp southern turn to run alongside Manassa Road.

It does not have a gravel or quarry stone base; the path of this trail is just the ground itself in its natural form.

[9] The parking lot at the eastern end of the visitor center (the lot used by trailers carrying water crafts using the reservoir's lake) opens to a trail that leads to the lake and which eventually connects to the eastern portion of the perimeter trail.

Continuing the trail is a small pedestrian wooden bridge followed by a resting bench facing the lake.

[14] The trail features about a dozen well-labeled indigenous flora and fauna, complete with their scientific name.

It provides access from Howell Township's Oak Glen Park to the Perimeter Trail.

In the back of the environmental center, there is also a hidden loop trail nearby leading to the lake.

An observation deck, with on-deck pay-for-view binoculars, complements the second-floor features of the center.

The western lot provides easy access to the 5.1-mile perimeter trail, children's playground, and a small picnic area facing the lake.

[16] Notable bird and land animal species in the area include: great blue heron, osprey, double-crested cormorant, and the bald eagle.
