Hiking in Monksville Reservoir: trails, map and practical info

Monksville Reservoir sits in the heart of Highlands region of northern New Jersey, tucked within Ringwood State Park. It's a wide, open body of water surrounded by forested ridgelines, and the trails that run along its shores give hikers a genuinely scenic experience that feels a world away from the surrounding suburbs. Whether you're looking for a peaceful morning walk or a longer outing with views over the water, this spot delivers.

The Setting

The reservoir itself was created in the 1980s when the Wanaque River was dammed to expand the regional water supply. What resulted is a large, irregularly shaped lake that now anchors the landscape of this part of Ringwood State Park. The surrounding terrain is classic New Jersey Highlands — rocky, wooded, and rolling — with mixed hardwood forest covering most of the hillsides. In the warmer months, the tree canopy fills in thick, and the trails feel enclosed and shaded. When the leaves drop in fall, the views open up considerably, and the reservoir becomes much more visible from the higher ground.

The area around Monksville Reservoir is also well known among anglers. Largemouth bass, striped bass, and walleye are among the species that draw fishing crowds to the shoreline and boat launches. If you're hiking here on a weekend, don't be surprised to see as many people with fishing rods as with hiking boots.

The Trails

The trail network around Monksville Reservoir connects with the broader system within Ringwood State Park, which means you have options depending on how much ground you want to cover. The paths near the reservoir range from flat, easy shoreline walks to more rugged routes that climb the surrounding ridges for elevated views over the water.

The terrain underfoot is typical of the Highlands — expect exposed rock, tree roots, and uneven ground in places, especially as you move away from the water's edge. Good footwear is worth it here even on shorter outings. The trails are generally well-marked, and the park's trail system uses a color-coded blaze system that's easy to follow once you get your bearings at the trailhead.

One of the draws of hiking in this area is the combination of water views and forest immersion. You're rarely walking along a completely open shoreline — instead, the trail weaves in and out of the trees, offering glimpses of the reservoir between the trunks before pulling you back into the woods. It gives the hike a varied feel that keeps things interesting.

Wildlife and Nature

The forests around Monksville Reservoir support a solid variety of wildlife. White-tailed deer are common, and you're likely to spot them early in the morning or near dusk. Birdwatching is a real draw here — ospreys and bald eagles have been spotted hunting over the reservoir, and the surrounding woods host a range of songbirds and woodpeckers. The mix of open water and mature forest creates good habitat diversity, which translates to more wildlife sightings than you'd get in a purely forested park.

The reservoir itself attracts waterfowl, particularly during migration seasons. Bring binoculars if you have them — scanning the water from a high point on the trail can be rewarding.

Practical Information

Monksville Reservoir is part of Ringwood State Park, which is managed by the New Jersey Division of Parks and Forestry. Parking is available at several access points within the park. As with most New Jersey state parks, there may be seasonal parking fees, so it's worth checking the current fee schedule before you go.

• Dogs: Dogs are permitted in Ringwood State Park but must be kept on a leash at all times.
• Fishing: A valid New Jersey fishing license is required to fish at Monksville Reservoir. There is also a boat launch area for those who want to get out on the water.
• Restrooms: Facilities are available at various points within Ringwood State Park, though availability at specific trailheads can vary by season.
• Cell service: Coverage can be spotty in the more forested sections, so downloading an offline map before you head out is a smart move.

Getting There

The reservoir is accessible from Sloatsburg Road and other access roads within Ringwood State Park in Passaic County, northern New Jersey. The area is reachable by car from the surrounding communities, and the park's main entrances are well-signed from the local roads. There is no direct public transit access to the trailheads, so a vehicle is essentially required.

What Makes This Place Worth the Trip

What sets Monksville Reservoir apart from a lot of other hiking destinations in northern New Jersey is the combination of open water scenery and genuine Highlands terrain. You're not just walking through flat woods — there's elevation change, rocky ground, and real views if you pick the right route. The reservoir adds a visual anchor that most purely forested parks in the region don't have.

It's also a spot that works well across different seasons. Spring brings wildflowers and migrating birds. Summer offers shaded forest hiking with water views as a reward. Fall is arguably the best time, when the hardwoods turn and the reservoir reflects the color. Winter, when the trails are snow-covered and quiet, has its own appeal for those who don't mind the cold.

If you're based in northern New Jersey or the greater New York metro area and looking for a half-day outdoor escape that feels genuinely removed from the urban environment, Monksville Reservoir and the trails of Ringwood State Park are a solid choice.
