New Jersey may be famous for its Atlantic beaches, but the state also has an impressive freshwater side. There are roughly 1,700 lakes, ponds, and reservoirs across New Jersey, offering opportunities for swimming, fishing, boating, kayaking, hiking, camping, picnicking, and wildlife watching.
The best lakes in NJ depend on what you want to do. Lake Hopatcong is a strong all-around choice for boating, fishing, swimming, and family recreation. Round Valley Reservoir stands out for swimming, hiking, fishing, boating, and wilderness camping. Wawayanda Lake combines swimming with extensive hiking, while Lake Marcia is a good choice for swimming and mountain scenery. Southern New Jersey adds a completely different experience through Pine Barrens lakes such as Atsion Lake and Lake Nummy.
This guide covers the best lakes in New Jersey by activity and region, explains which lakes are suitable for swimming, fishing, boating, or families, and provides practical information about fees, park capacity, water conditions, and seasonal rules.
Information checked: September 2026. Lake conditions, swimming schedules, fees, closures, and access rules can change, so verify current information with the relevant park or New Jersey state agency before traveling.

15 Best Lakes in New Jersey
1. Lake Hopatcong: Best Overall
Lake Hopatcong is one of the first places to consider when searching for the best lakes in NJ. New Jersey State Parks identifies it as the largest lake in New Jersey, with about 2,500 acres of freshwater and roughly nine miles of length.
Its biggest advantage is variety. Visitors can find opportunities for swimming, fishing, boating, picnicking, and family recreation in and around Hopatcong State Park. The park also has a boat launch, playground equipment, sports facilities, and picnic areas.
Lake Hopatcong is particularly suitable if your group cannot agree on one activity. One person can fish, another can enjoy the water, and the family can spend time together at a picnic area.
Best for: boating, fishing, swimming, families, and an all-around lake day.
2. Round Valley Reservoir: Best for Swimming, Hiking and Camping
Round Valley Reservoir is one of New Jersey’s most distinctive freshwater destinations.
The reservoir covers approximately 2,350 acres and reaches about 180 feet deep, making it the state’s largest reservoir and its second-deepest lake. The surrounding recreation area offers boating, fishing, hiking, picnicking, swimming, and camping.
One of Round Valley’s biggest advantages is its wilderness camping. New Jersey State Parks describes it as the only New Jersey state park offering wilderness camping. Campsites are reached by boating or by hiking roughly three to six miles along a steep and rugged trail.
Swimming is available only at the designated lifeguarded swimming area, not throughout the main reservoir.
Best for: swimming, hiking, fishing, boating, camping, and adventurous weekend trips.
3. Wawayanda Lake: Best for Swimming and Hiking
Wawayanda Lake sits inside Wawayanda State Park in northern New Jersey, surrounded by forested hills and extensive trails.
The park offers swimming, boating, canoeing, kayaking, fishing, camping, picnicking, and hiking. More than 60 miles of trails are marked throughout the park, while a 19-mile stretch of the Appalachian Trail passes through the area.
The lake is also interesting for anglers. New Jersey State Parks lists largemouth and smallmouth bass, perch, pickerel, brown and rainbow trout, and occasional lake trout among the fish found in Wawayanda Lake.
For swimming, the park currently lists the beach as open Wednesday through Sunday from 10 a.m. to 5:30 p.m. during the 2026 season, subject to current conditions and park operations.
Best for: swimming, hiking, kayaking, fishing, camping, and nature.
4. Swartswood Lake: Best for a Quiet Natural Setting
Swartswood Lake offers a more peaceful alternative to some of New Jersey’s busier recreational lakes.
Located within Swartswood State Park, the lake covers about 519 acres and is a natural glacial lake. Only electric motors are permitted, so the lake has a quieter atmosphere than destinations where larger gas-powered boats dominate.
The park offers swimming, fishing, boating, canoeing, kayaking, camping, picnicking, and hiking.
Fishing is available year-round, with species including trout, bass, sunfish, catfish, walleye, perch, and pickerel.
Best for: peaceful boating, fishing, swimming, kayaking, and scenery.
5. Lake Marcia: Best for Mountain Scenery
Lake Marcia is located inside High Point State Park in Sussex County.
The spring-fed lake covers approximately 20 acres and offers a designated swimming area during the summer when lifeguards are on duty. The beach area includes changing rooms, picnic tables, grills, and a snack stand.
One important difference is that boats, kayaks, paddleboards, and other personal watercraft are not permitted on Lake Marcia. That makes it much more focused on swimming, picnicking, hiking, and enjoying the surrounding High Point landscape.
Best for: swimming, families, hiking, picnicking, and mountain scenery.
6. Greenwood Lake: Best for Boating and a Two-State Lake Experience
Greenwood Lake is unusual because it extends across the New Jersey-New York border.
It is particularly associated with boating, fishing, paddling, and waterfront recreation. Because access points and regulations can differ on the New Jersey and New York sides, visitors should confirm the specific launch, beach, or facility they intend to use.
Greenwood Lake can be a good choice for visitors who want a developed lakeside environment rather than a remote state-park experience.
Best for: boating, fishing, paddling, and a North Jersey/New York day trip.
7. Spruce Run Reservoir: Best for Boating and Fishing
Spruce Run Reservoir in Hunterdon County covers about 1,290 acres and has approximately 15 miles of shoreline. New Jersey State Parks identifies it as the state’s third-largest reservoir after Round Valley and Wanaque.
The reservoir supports motor boating, sailing, canoeing, kayaking, windsurfing, and paddleboarding. Gas and electric motors are permitted, with a 10-horsepower limit, while jet skis are not permitted.
Fishing opportunities include largemouth bass, catfish, sunfish, yellow perch, and carp.
There is an important 2026 update, however: the Spruce Run swimming area is currently listed as closed for the 2026 season. The reservoir also has an ongoing harmful-algal-bloom advisory, so visitors should check the current status before recreating on or in the water.
Best for: boating and fishing, not a 2026 swimming trip.
8. Manasquan Reservoir: Best for Hiking and Nature
Manasquan Reservoir is a strong choice if your idea of a lake day involves walking trails rather than swimming.
The reservoir area is known for hiking, fishing, wildlife viewing, and outdoor recreation. It is better suited to people who want to explore a natural setting than visitors specifically looking for a traditional lake beach.
Best for: hiking, walking, fishing, wildlife, and nature photography.
9. Hooks Creek Lake: Best for Families
Hooks Creek Lake is located within Cheesequake State Park in Matawan.
The six-acre lake has a designated swimming area, and the surrounding park includes a beach complex, changing areas, restrooms, a first-aid station, and a concession area.
Small cartop boats, canoes, kayaks, and paddleboards can be launched at Hooks Creek Lake, with electric motors permitted. The lake also provides freshwater fishing opportunities, including largemouth bass, sunfish, and catfish.
The surrounding Cheesequake State Park adds hiking, picnicking, camping, and nature activities, making it useful for a full family day rather than a swim-only visit.
Best for: families, swimming, picnicking, kayaking, and short outdoor trips.
10. Atsion Lake: Best Pine Barrens Lake
Atsion Lake provides a very different New Jersey lake experience because it is located in the Pine Barrens.
The lake is part of the Atsion Recreation Area, which offers swimming and other outdoor recreation. The park also provides camping and opportunities to experience the surrounding Pine Barrens landscape.
Atsion is particularly attractive if you want freshwater swimming combined with forest scenery rather than the mountain environment found in northern New Jersey.
The current state park page lists summer entrance fees, with different rates for New Jersey residents and non-residents, while the off-season period is free.
Best for: swimming, camping, families, and Pine Barrens scenery.
11. Lake Nummy: Best for Southern NJ Swimming and Camping
Lake Nummy is located inside Belleplain State Forest in Cape May County.
The lake was created from a former cranberry bog and is now used for swimming, boating, fishing, and outdoor recreation. Belleplain also provides more than 40 miles of trails for hiking, biking, and horseback riding.
Swimming is permitted during the summer when lifeguards are on duty. The beach complex includes changing facilities, restrooms, first aid, and playground equipment.
Small boats and personal craft such as canoes, kayaks, and paddleboards can be launched, while powered boats are limited to electric motors.
Best for: swimming, camping, hiking, paddling, and southern New Jersey nature.
12. Merrill Creek Reservoir: Best for Fishing and Wildlife
Merrill Creek Reservoir is a better choice for people who want a quiet nature and fishing experience rather than a conventional swimming beach.
It is among the freshwater destinations worth considering for anglers and visitors interested in wildlife and hiking.
New Jersey Fish & Wildlife maintains detailed information about publicly accessible lakes and reservoirs, including fishing species, boat access, ramps, swimming areas, and other characteristics.
Best for: fishing, hiking, wildlife, and peaceful scenery.
13. Budd Lake: Best Natural-Lake Option
Budd Lake in Morris County is commonly recognized as one of New Jersey’s notable natural lakes.
It is a useful choice for people who specifically want a natural-lake setting rather than a large state-built reservoir.
Because public access and recreation can differ from one part of a lake to another, confirm current swimming, boating, parking, and fishing rules before planning a trip.
Best for: a natural-lake setting and North Jersey recreation.
14. Sunrise Lake: Best for a Family Beach Day
Sunrise Lake is a family-oriented recreation option in Morris County.
It is known for its swimming and beach activities, with seasonal attractions that can make it more appealing to families with children than a remote fishing reservoir.
If you’re choosing between several New Jersey lakes for a family day, consider the age of your children, available facilities, parking, admission costs, and current operating schedule rather than focusing only on the lake itself.
Best for: families and a traditional summer lake day.
15. Lake Mohawk: Best for Scenic Lakeside Atmosphere
Lake Mohawk in Sussex County offers a different type of lake experience from the state’s public recreation areas.
Its appeal is strongly connected to its surrounding community, waterfront setting, and scenic atmosphere.
Because access and recreation rules can be more restrictive than at public state-park lakes, visitors should confirm whether the specific activity they want—such as swimming, boating, or fishing—is available to the public.
Best for: scenery and a lakeside community atmosphere.
Best Lakes in NJ for Swimming
If swimming is your main goal, do not assume that every lake allows public swimming.
New Jersey State Parks states that swimming on state park property is permitted only in designated areas when lifeguards are on duty. The current state swimming schedule should be checked before leaving home.
Best Swimming Lakes for Families
Good places to investigate include:
- Lake Marcia
- Wawayanda Lake
- Round Valley Reservoir
- Swartswood Lake
- Hooks Creek Lake
- Lake Nummy
- Atsion Lake
- Lake Hopatcong
The best choice depends on whether you want a simple beach day or additional activities such as hiking, camping, kayaking, or fishing.
Current 2026 Swimming Schedule
For several major state-park lake swimming areas, the current 2026 schedule lists:
- Round Valley Recreation Area: Wednesday–Sunday, 10 a.m.–5:30 p.m.
- Swartswood State Park: Wednesday–Sunday, 10 a.m.–5:30 p.m.
- Wawayanda State Park: Wednesday–Sunday, 10 a.m.–5:30 p.m.
All three are currently listed as closed Monday and Tuesday for swimming.
Schedules can change because of weather, staffing, water conditions, or other park circumstances.
Best Lakes in NJ for Fishing
New Jersey is particularly strong for freshwater fishing. Fish & Wildlife says the state has more than 400 publicly accessible lakes, ponds, and reservoirs. Its official database provides information about fish species, boat ramps, car-top launches, swimming areas, and other features.
Lake Hopatcong
Lake Hopatcong is a versatile choice for recreational fishing and other water activities.

Best Lakes in NJ for Boating and Kayaking
Best for Motorboating
Lake Hopatcong and Spruce Run Reservoir are strong choices for visitors interested in motorized boating, subject to current regulations.
Spruce Run allows electric and gas motorboats up to 10 horsepower and prohibits jet skis.
Best for Kayaking and Canoeing
Wawayanda Lake, Swartswood Lake, Round Valley Reservoir, Hooks Creek Lake, and Lake Nummy are worth considering for paddling.
Rules differ by location. For example, Swartswood permits only electric motors, while Lake Marcia does not allow boats, kayaks, or paddleboards at all.
Check Wind Conditions
Round Valley and Spruce Run have a specific wind-related boating restriction. When wind reaches or exceeds 25 mph, boating operations must stop and boats must leave the water.
That is one reason checking the weather is essential before launching a boat.
Best Lakes in NJ for Families

Look for:

Greenwood Lake crosses the New Jersey-New York border and offers boating and waterfront recreation.
Wawayanda Lake

Actual driving time from New York City can vary substantially with traffic, especially on summer weekends, so check current navigation conditions rather than relying on a fixed travel-time estimate.
Are Lakes in NJ Free to Visit?
Some are free during parts of the year, while others charge seasonal entrance or parking fees.
New Jersey State Parks commonly apply entrance fees from Memorial Day weekend through Labor Day, with different rates for residents and non-residents at many locations. Some parks are free outside the main summer fee period.
For example, current state information lists seasonal entrance fees at:
- Hopatcong State Park
- Round Valley Recreation Area
- Swartswood State Park
- Wawayanda State Park
- Spruce Run Recreation Area
- Atsion Recreation Area
Fees can differ by weekday, weekend, holiday, residency, and type of vehicle.
Before traveling, check the individual park’s current fee schedule.
When Is the Best Time to Visit Lakes in NJ?
Summer
Summer is the best season for traditional lake activities such as swimming, kayaking, boating, and beach days.
It is also the busiest period.
New Jersey State Parks warns that popular swimming areas can reach capacity during summer weekends and holidays. When a park reaches capacity, vehicles and visitors can be turned away.
Spring
Spring is excellent for hiking, fishing, birdwatching, and enjoying cooler weather.
Swimming may not yet be available, and water temperatures can remain cold.
Fall
Fall is one of the best seasons for scenic lake trips in northern New Jersey.
Forested destinations such as Wawayanda, Swartswood, and Round Valley can be particularly attractive when foliage changes.
Winter
Some lakes remain useful for hiking, wildlife viewing, ice fishing, or other cold-weather activities where specifically permitted.
Never assume frozen water is safe for walking, skating, or other activities. Check official conditions and rules before entering ice.
What to Know Before Visiting a New Jersey Lake
Check Whether Swimming Is Actually Allowed
A lake can look perfect for swimming while still prohibiting it.
At New Jersey State Parks, swimming is permitted only in designated areas while lifeguards are on duty.
Check the Current Water Conditions
Water conditions can change during the season.
New Jersey DEP monitors lakes and provides information about harmful algal blooms and other water-quality concerns.
If an official advisory is posted, follow it rather than relying on how clear or clean the water appears.
Check Park Capacity
Popular swimming areas can fill to capacity during hot summer weekends and holidays. NJDEP recommends checking its park operating status before traveling.
Check Weather Before Boating
Wind can affect both safety and whether boating is permitted.
At Round Valley and Spruce Run, boating must stop when wind reaches or exceeds 25 mph.
Check Fishing Requirements
If you’re planning to fish, confirm whether you need a current New Jersey fishing license and whether the waterbody has special rules.
NJ Fish & Wildlife provides official information about freshwater fishing locations and regulations.
Check Boat Launch Rules
Not every lake permits every type of boat.
Some locations allow gas-powered boats, some restrict motors, and some prohibit watercraft altogether. Lake Marcia, for example, does not permit boats or personal watercraft, while Spruce Run allows specified motorized and non-motorized boating.
