Swartswood State Park

About Swartswood State Park

If you want to see why people fall in love with Sussex County, Swartswood State Park is a pretty good place to start. It sits across Stillwater and Hampton townships and covers 3,460 acres, which sounds abstract until you’re actually standing on the shore of Swartswood Lake looking at how far it stretches in either direction. This is New Jersey’s oldest state park, dating back to 1915, and the story behind that is worth knowing. A local landowner named George Emmans donated the first ten acres with the simple wish that the land stay open to the public forever, and public pressure eventually forced the state to buy the lake itself from a private owner who’d been charging a dollar a day just to access it. That history still shapes how the place feels today. It was set aside for people, not developers, and it shows.

The Lakes

Swartswood Lake is the headline attraction, and at 519 acres it’s the third-largest natural freshwater lake in New Jersey. What makes it special isn’t just the size though, it’s the fact that only electric motors are allowed on the water. No jet skis, no gas engines roaring across the surface, just the quiet glide of canoes, kayaks, and sailboats. That single rule keeps the whole lake feeling calm in a way that’s rare this close to the New York metro area. A short drive or hike away is Little Swartswood Lake, an 84-acre glacial lake that offers the same peaceful boating and fishing experience on a smaller scale, minus the swimming.

Swimming and Picnicking

The main beach is open with lifeguards on duty Wednesday through Sunday from Memorial Day through Labor Day, and it comes with the basics you’d want for a full day out: changing areas, restrooms, showers, a first aid station, and a concession stand for when the kids inevitably get hungry. Outside of swim season, the shoreline is still worth visiting for the picnic areas and grills scattered around the park, plus a couple of playgrounds if you’ve got young children in tow. Swartswood is included in New Jersey’s freshwater beach monitoring program, and the state posts advisories or closures when testing turns up a problem. NJDEP also runs a separate status system for harmful algal blooms. Between those two and the occasional lifeguard shortage, the beach can close on short notice, so if swimming is the whole point of your trip, check the current status before you load up the car.

Swimming is only permitted while lifeguards are on duty, which ends at 5:30 pm, even though the park is open until 8:00 pm. Unlike Hopatcong State Park and Island Beach State Park, it is highly unusual for Swartswood to have to close due to capacity issues, so don’t sweat that.

Dogs are permitted in the park but are not allowed on the sandy beach area. If you bring your dog, it must remain in the grassy area behind the beach at all times.

Fishing and Boating

Fishing here runs year-round and draws a steady crowd of anglers who know the lakes are stocked each spring with brown, rainbow, and brook trout. Come summer and fall, the same waters produce bass, sunfish, catfish, walleye, perch, and pickerel, and you can fish either from shore or by boat depending on how you like to spend your morning. If you don’t have your own gear or boat, the park offers kayak rentals in season for self-guided tours along the Swartswood Lake Water Trail, which is a nice, low-effort way to get out on the water without hauling your own equipment.

Thousands of Trout Stocked Every Year

The State of New Jersey stocks Swartswood Lake and Little Swartswood Lake with thousands of trout each year. Trout stocking dates and locations are available online.

Anyone 16 years of age or older must have a valid fishing license to fish in New Jersey’s fresh waters, including privately owned waters, using a handline, rod and reel, or bow. A trout stamp is also required to fish for trout or salmon, even if you plan to release your catch.

Kayak Rentals

Kayaks are available to rent on Saturdays and Sundays, with the last boat departing at 3:00 p.m. Single-seat kayaks cost $15 per hour, and double-seat kayaks cost $30 per hour. Rentals are limited to a maximum of two hours.

Life jackets are required, and renters must bring their own. Swimming from the kayak is not permitted. At least one person in each kayak must be 15 years of age or older. Anyone under 18 must have a parent or guardian sign the rental agreement.

Payment must be made in cash at the park office before proceeding to the kayak rental area. Rentals are available on a first-come, first-served basis, and reservations are not accepted. Refunds are not provided for early returns, cancellations, no-shows, or inclement weather.

For additional information, contact the park office at (973) 383-5230.

What You’ll See Out on the Lake

Camping and Hiking

For anyone who wants to stay longer than a day, there are 65 tent and trailer campsites, each with a fire ring, picnic table, and lantern holder, along with three group sites near Duck Pond and six shelters on a shaded ridge for anyone who wants a slightly more comfortable version of roughing it.

There’s no RV hookup on site, but there is a dump station, so it’s still workable for people traveling with larger rigs. There are a good number of both shaded grass sites and fully wooded sites, depending on your preference. Campsites are reserved using the state’s online campsite reservation system.

Camping with a dog is restricted to sites 42 through 45 with a per-night fee and rabies paperwork at check-in.

Hiking is another big draw, with trails winding through the surrounding hills and forest that connect into the broader Kittatinny Valley landscape, and mountain streams like Neldon’s Brook cutting through the property add some nice variety beyond just the lakes. Check out the Swartswood State Park Hiking Map for full trail descriptions.

Wildlife and Winter Activities

Wildlife watching is genuinely one of the underrated reasons to visit. The park has a healthy resident population of bald eagles, and sightings of mature or immature eagles happen often. Regulars bring binoculars as a matter of habit. Beyond eagles, you’ll find other birds of prey, waterfowl, and occasionally larger mammals like black bear and bobcat passing through the connected wildlife management areas nearby. In winter, the park shifts gears entirely and opens up for cross-country skiing, sledding, ice skating, and ice fishing, so it’s genuinely a four-season destination rather than just a summer lake escape.

Nearby Dining

After spending the day on the water or the trails, you won’t have to travel far for a good meal. North Shore House, a restored 1930s lakefront inn on Swartswood Road, serves up locally sourced fare with sweeping views of the lake at its Blue Heron Tavern. A few minutes away, the Hyde-Away Restaurant & Tap Room offers a more laid-back vibe with New American, Latin, and Italian dishes alongside a solid rotating beer selection. Both make for an easy way to cap off a day at Swartswood.

Getting There

Getting there is straightforward if you’re coming from Route 80. Take exit 25 onto Route 206 north toward Newton, about 12 miles, then turn left at the second light onto Route 519 and follow signs from there. Whether you’re planning a quiet afternoon of fishing, a full weekend of camping, or just a scenic drive out to look at the water, Swartswood is one of those Sussex County spots that rewards the trip out, especially since it sits far enough from the highway that it still feels like a genuine escape rather than another crowded roadside attraction.

Entrance Fees

Entrance fees are charged per vehicle from Memorial Day weekend through Labor Day, and go towards helping keep the park well maintained. Admission is free during the rest of the year.

Buses are permitted by reservation only and may visit on weekdays. Frequent visitors may also purchase an annual New Jersey State Parks pass, which provides unlimited admission to all New Jersey state parks for the year. New Jersey residents age 62 and older are eligible for a free lifetime senior citizen pass.
