Mountainside is the Union County town that trades sidewalks for trails. Perched on a ridge in the Watchung Mountains and wrapped around a 2,065-acre nature preserve, this small, affluent borough offers something its busier neighbors can't: genuine quiet, privacy, and space. Mid-century ranches and modern custom colonials sit on half-acre lots along meandering, canopied streets — some backing directly onto the Reservation, a few with Manhattan skyline views. Add top-rated schools and, unusually for New Jersey, a relatively light property-tax bill, and Mountainside makes a quiet but compelling case. The honest tradeoff: there's no train here, so you'll drive or bus to the city rather than walk to a platform.
The Argument in Brief
Mountainside offers privacy, space, and nature at a premium address — spacious homes on wooded half-acre lots beside a 2,000-acre preserve, feeding into top schools, with a property-tax bill that's relatively gentle for the area thanks to its Route 22 commercial base. The catch is the commute: no train station means a bus to Port Authority or a drive to a neighboring town's station. Buy here for the setting and the schools; go in clear-eyed about the car-first commute.
The defining feature of Mountainside is the land it wraps around. The Watchung Reservation is Union County's largest park — more than 2,000 acres of forest, trails, lakes, and history, with the Trailside Nature & Science Center, the Watchung Stables, and miles of hiking and bridle paths. For residents, it's a backyard wilderness: many homes sit a short walk or even directly adjacent to the preserve, and Echo Lake Park adds still more green space. If your idea of home includes trees, trails, and quiet over storefronts and sidewalks, this is the heart of the appeal — explored in our guide to the Watchung Reservation and outdoor living.
Here's the honest tradeoff for all that quiet: Mountainside has no train station. Commuters typically take NJ Transit's bus line 114 to the Port Authority in Midtown — around an hour — or drive a few minutes to catch a train in Westfield, Cranford, Summit, or Berkeley Heights. Route 22 and Interstate 78 flank the borough, putting Newark about 13 miles away and lower Manhattan roughly 25. It's a car-first life, which suits many buyers fine, but it's the single most important practical difference from the county's rail towns. We lay out every option in our Mountainside commute guide.
Mountainside's housing tells a story of mid-century New Jersey growing up. Ranches and split-levels from the 1950s and 60s sit beside newer contemporary colonials and custom rebuilds, most on half-acre lots along hilly, tree-lined streets. The most coveted homes back onto the Reservation or catch a ridge-top glimpse of the New York skyline. It's a low-density, single-family borough through and through — no condos or downtown, just houses and woods. Our neighborhoods and homes guide maps the borough's pockets and what your budget reaches.
Here's the pleasant surprise. In a state famous for punishing property taxes, Mountainside's tend to run relatively light for the area — a benefit of its Route 22 commercial base, where business ratables help offset the residential burden. For an affluent town with large lots and strong schools, that's a genuine rarity worth understanding before you compare it to neighbors.
We break down what you'll actually pay, and how to verify it, in our Mountainside property taxes guide.
Mountainside runs its own small, well-regarded district for the younger grades — Beechwood School for the earliest years and Deerfield School through eighth grade — then sends high-schoolers to Governor Livingston High School in neighboring Berkeley Heights through a long-standing send-receive relationship. It's a structure worth understanding before you buy, and we cover it in our Mountainside schools guide.
For New York and Staten Island buyers craving room to breathe, Mountainside offers a rare combination: wooded privacy, a nature preserve at the doorstep, top schools, and a lighter tax bill than many premium towns — within about 25 miles of Manhattan. The price of entry is real, and so is the car-first commute, but for the right household it's a genuine lifestyle upgrade. We make the full case in moving to Mountainside from New York.
Mountainside is a low-inventory, premium market where homes span a wide price range and the right buyer is often relocating from out of area.

Trading the city for trees and space?
Mountainside is exactly the kind of move many of The Prodigy Team's New York and Staten Island buyers dream about — privacy, a preserve at the back door, and top schools within reach of the city. We work both sides of the water and know how to match a Mountainside home to a New York buyer, and how to sell one to the people most likely to want it.

See What Your Mountainside Home Is Worth
Mountainside is a quiet, affluent borough wrapped around the 2,065-acre Watchung Reservation, offering spacious homes on wooded half-acre lots, top-rated schools, and relatively light property taxes for the area. The main tradeoff is the absence of a train station, so commuting means a bus or a drive to a nearby station.
Mountainside is among Union County's higher-priced towns, with a median sale price roughly around $1 million and a wide range — from the mid-$600,000s to nearly $3 million — depending on size, lot, and condition. Figures vary by source and time period, so confirm current comparable sales for any specific home.
No. Mountainside has no train station of its own. Commuters typically take NJ Transit bus line 114 to the Port Authority in Midtown Manhattan, about an hour, or drive a few minutes to catch a train in Westfield, Cranford, Summit, or Berkeley Heights. Route 22 and Interstate 78 provide highway access.
For the area, they tend to be relatively favorable, helped by the borough's Route 22 commercial tax base, which shares the burden that falls heavily on residents in many other towns. It's an unusual advantage for an affluent Union County community, but you should confirm the current rate and a specific property's bill.
