Statistically speaking, Mountainside is a winning borough. It ranked #1 in Union County and #8 in the state on the 2010 “Best Places to Live in New Jersey” list produced by New Jersey Monthly magazine, and the Mountainside Community Pool was voted #3 Best Public Pool in the state by Inside NJ magazine.
This small borough, measuring about four square miles, shares its borders with upscale towns including Summit, Westfield, Berkeley Heights, Scotch Plains and Springfield Township. The borough has a population of approximately 7,100 residents.
Mountainside’s name was created in 1895, when local farmers decided to separate from Westfield for a “simpler life.” In subsequent decades it remained a quiet, rural town. Much of the commercial and residential development seen in the borough today is the result of a post-World War II development boom.Back to top

Watchung Reservation: A strikingly beautiful 2,000-acre wooded reservation with facilities for horseback riding, hiking and fishing. The reservation features an arboretum, athletic field, bridle trails, cross country ski course, model airplane flying, nature trails, picnic areas, playground, and the deserted village of Feltville.
The Watchung Riding Stable: This state-of-the-art facility is located on Summit Lane in Mountainside and features extensive programs for all ages.
