Situated on the western outskirts of Newark, Mountainside is a leafy borough in New Jersey. Surrounded by parklands, reservations and golf courses, it’s considered one of the top residential areas in the state and the ideal destination to rent an RV.

Mountainside was officially incorporated in 1895 and installed with a Nike missile battery during the late 1950s. Today, it’s an attractive base for RV enthusiasts thanks to its surrounding natural beauty and proximity to the bright lights of Newark and New York City.

Discover Mountainside


The Great Outdoors

Pick up your camper rental in Mountainside and make the short drive east to the Echo Lake Park, a popular recreational destination in Union County. It centers around a sprawling lake where you can go fishing and boating, as well as ice skating during the winter months. Take in the park’s natural beauty along the lakeside walking trail or let your four-legged friend run loose in the dog park. There’s also a shaded children’s playground that features monkey bars and twisting slides, as well as a climbing wall and bridges.

Just to the west of Mountainside lies the Watchung Reservation, which nestles in a valley between First Watchung Mountain and Second Watchung Mountain. It’s the largest nature reserve in Union County and crisscrossed by numerous hiking and horseback riding trails, as well as being home to fishing ponds and the sparkling waters of Lake Surprise. If you’re traveling with kids, they can let off some steam in the Loop Playground or browse the exhibits at the Trailside Nature & Science Center.

Or, you can head north to the South Mountain Reservation near Maplewood, which encompasses just over 2,000 acres on the Rahway River. It was created in the late 19th century by the Olmsted Brothers and has been preserved largely in its wild state, with hardwood forests, meandering streams, and waterfalls to explore. Soak up the views towards New York and the Jersey City skylines or get active at the Treetop Adventure Ropes Course and in the Turtle Back Zoo.

RV Parks

Book a motorhome rental in Mountainside and make the short drive east to the Liberty Harbor RV Park, which is the closest RV park to New York City. Aside from views towards the NYC skyline from its 50 RV sites, there’s also complimentary Wi-Fi, an on-site laundry facility, and a restaurant/bar if you want to eat out.

RVers holding a military ID can book a spot at the Navy Earle MWR RV Park, a tiny camp with just 15 sites that’s located within the military base. Guests are welcome to participate in a range of activities organized by the base while taking advantage of the 20, 30 and 50-amp service RV facilities.

Exploring the City

Pick up your RV rental near Mountainside and visit the Miller-Cory House Museum, which dates to 1740 and is now listed on the National Register of Historic Places. Wander through the period-furnished rooms to learn about life during the 18th century and explore the picturesque gardens that feature typical early American plantings. It’s located in Westfield and just a short drive from the Hanging Tree Historic Site where American soldier James Morgan was executed for killing Reverend James Caldwell in 1781.

If you’re a serious foodie, make the 10-minute drive from Mountainside into Cranford, which is home to a number of gourmet restaurants and eclectic cafes. You can work off your meal while strolling through the township’s historic streets and visit the oldest continuously operated commercial building in New Jersey at Droescher’s Mill. Cranford is also home to the historic Crane-Phillips House Museum that offers a glimpse into what life was like for Victorian-era families.

Mountainside makes a good base for visiting Newark where you can browse the American artworks on display at the Newark Museum or take in a show at the New Jersey Performing Arts Center. Leave your travel trailer rental in Mountainside and jump on a train into the heart of New York City to explore its iconic landmarks and legendary museums.
