Weighing Mountainside against nearby towns? See how it stacks up on price, schools, and commute → Find Your Town

Want space, nature at your back door, and lower taxes than your pricey neighbors — minutes from two of the best downtowns around? Mountainside delivers. This peaceful, wooded Union County borough wraps around the Watchung Reservation, offering larger lots and a quiet, upscale feel while keeping Westfield and Summit just minutes away. A favorite for buyers who want privacy and green space without going remote.

🏡 Why buyers love Mountainside
✅ Nature in your backyard. The borough borders the 2,000-acre Watchung Reservation and Echo Lake Park — hiking, biking, horseback riding, and trails right at hand.
✅ Space and lower taxes. Larger lots than neighboring towns, plus noticeably lower property taxes than Summit or Westfield — a big reason the market here is so competitive.
✅ Strong schools. Mountainside runs its own K–8 district (Beechwood and Deerfield), with high schoolers attending the highly-rated Governor Livingston in Berkeley Heights.
✅ Minutes from the best downtowns. Mostly residential and quiet, but the shops and restaurants of downtown Westfield and Summit are a short drive away.

🚉 The commute
Mountainside has no station of its own, but you're spoiled for options. The 114/114X express bus runs a one-seat ride from Route 22 straight to Port Authority (about 60–75 minutes). Or drive a few minutes to Summit (3 miles north) for frequent direct trains to Penn in 45–55 minutes, or to Westfield (3 miles south) for the Raritan Valley Line. Between them, real flexibility.
