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 mostly across Stillwater and Hampton townships and covers something like 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 roughly 500 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 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. Just keep in mind that swimming can occasionally be closed due to water quality advisories or lack of sufficient lifeguard staff, so if that’s the main reason for your trip, it’s worth calling ahead or checking the current status before you load up the car.
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.
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 a group campsite and a handful of yurts for people who want 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. 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.
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 enough that 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. There’s a modest entrance fee, a few dollars for New Jersey residents and a bit more for out-of-state visitors, which goes toward keeping the park maintained. 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.
