DESCRIPTION: The best of the best! This playground is awesome. As you enter the park you feel like you’re on vacation. There is an ampi-theater with seating, a fountain, a spray ground, and a massive playground. The playground has three structures in a completely enclosed area that has solid surface ground cover. The equipment is all new with tons and tons of climbing and playthings. There are plenty of swings for everyone.

PARKING: Street parking
PICNICKING: There are several tables throughout the park but also plenty of room to lay out a blanket for a picnic.
HANDICAP: There is one handicap swing but this ground surface makes it a dream to maneuver around. There are plenty of playthings down low to be able to have an afternoon of fun.
CLIMBING: Corkscrew poles, climbing walls, monkey bars, ring, swinging rings, log rolls, pedal runners, bridges, tunnels, mushroom caps, spider web climber

WALKING PATHS: Paved throughout the entire park
WATER: Nice fountain in the center of the park that has two levels of spraying
OTHER COOL STUFF: The park has a spray ground that is open to the public. The playground is open daily from 9am to 8pm. At closing, the gates to both areas are locked. The town provides security for each area during open hours.
MAKE A DAY OF IT: I doubt you’ll need to leave but if you want to get out of the sun, there is a shopping plaza right across the street with several stores like Dollar Tree, Chinese food restaurants, Dunkin Donuts, etc.

367 Valley Brook Avenue, Lyndhurst, NJ. Sprayground in Summer open 10AM-4PM. Picture worth a thousand words, great sprayground fenced in for the younger kids, bring a chair if you want a seat, some benches but it can get crowded. You can park on the side of the playground. So both areas are fenced, and there is some shade, but not on all structures.

My son loved this park, and can’t wait to go again. The playground is mainly school-age, 5 and up. Swings for both toddler and older kids. Very nice people there, very NEW park, and excited for Lyndhurst, I loved the volunteers there, they are identified by the police t-shirts and are very dutiful in making sure the kids follow the arrows down the spray tunnel and don’t stand on the spray jets (which my sons seem to enjoy most).
