Buttermilk Falls

About Buttermilk Falls

Tucked away in the rolling hills of Mendham Township, Buttermilk Falls is one of northern New Jersey's most rewarding and quietly kept secrets. The falls tumble over ancient rock in a series of frothy cascades before pooling at the base into a cool, spring-fed swimming hole that feels worlds removed from the suburban sprawl of nearby Morris County. Getting here requires a moderate hike through wooded terrain — steep in places, with roots and uneven footing that demand sturdy shoes — but the payoff is a scene of unspoiled beauty that draws hikers, swimmers, and photographers alike.

The Setting and Landscape

The trail to Buttermilk Falls winds through a dense canopy of hardwoods and hemlock, where light filters in shifting patterns and birdsong replaces the noise of everyday life. As you descend toward the water, you begin to hear the falls before you see them — a persistent, rushing murmur that grows louder with each step. When the waterfall finally comes into view, cascading white over dark, moss-draped ledges and into a shaded stone basin, it's the kind of sight that stops you mid-stride. Spring and early summer bring the falls to their fullest expression, swollen with snowmelt and rainfall, while autumn wraps the surrounding hillside in fiery oranges and reds. Even in winter, the falls transform dramatically, freezing into curtains of glittering ice — a striking, otherworldly tableau for those willing to make the cold trek.

Swimming at Buttermilk Falls

The swimming hole at the base of the falls is intimate and naturally secluded, fed by cold spring water that keeps temperatures refreshing even on the hottest July afternoons. The clarity of the water is a hallmark of spring-fed pools — you can often see straight down to the rocky bottom, where smooth stones shift and glimmer in the light. Swimmers tend to wade in gradually, feeling the chill tighten around them before surrendering to the cool embrace. Because this is an unofficial swimming site with no facilities, no lifeguards, and no safety staff on-site, swimmers are entirely responsible for their own well-being. The depth of the pool can vary with seasonal conditions, so enter carefully and use good judgment, especially with children.

Practical Visit Information and Local Character

There are no fees to visit Buttermilk Falls, though the lack of facilities means you'll want to pack everything you need — water, snacks, and a change of clothes if you plan to swim. There are no restrooms, no parking attendants, and no designated amenities at the site. The trail features moderate difficulty, with steep sections requiring solid footing and genuine attention. Wear hiking boots or trail shoes rather than sandals, and be prepared for slippery rocks near the water's edge. The swimming here is unofficial, so visit with awareness, tread lightly, and pack out everything you bring in. Wildlife sightings — from songbirds to deer — add to the sense that this corner of New Jersey remains blessedly unspoiled.

Plan Your Visit: Buttermilk Falls sits near the charming towns of Mendham and Morristown, both of which offer excellent dining, lodging, and historic sites to round out your day. Morristown in particular is rich with Revolutionary War history and walkable town amenities, making it an easy base for exploration. Allow at least half a day for the hike and a proper swim.
