The Dunnfield Creek Natural Area Trail is one of the most accessible and scenic hikes within the Delaware Water Gap National Recreation Area in New Jersey, beginning just off I-80 Exit 1 on the New Jersey side near Columbia, Warren County. The trailhead sits at the Old Mine Road parking lot with free roadside parking directly at the start. The trail follows Dunnfield Creek upstream through a hemlock gorge, crossing the creek multiple times on stepping stones and footbridges as it climbs 230 meters over 3.2 kilometers to reach Sunfish Pond — a glacial lake and federally designated Natural Landmark resting at approximately 390 meters elevation.
The trail surface is predominantly rocky and root-covered, with exposed river cobble near creek crossings and compacted dirt through the hemlock shade sections. Water bars and basic timber steps appear on the steeper upper portions. Creek crossings can be wet during spring snowmelt and after heavy rain; waterproof hiking boots are strongly advised. The trail is well-marked with green and white blazes and connects with the Appalachian Trail at Sunfish Pond, offering experienced hikers the option to extend onto the Kittatinny Ridge for panoramic views.
The primary attraction is the series of cascades and small waterfalls along Dunnfield Creek, which are most dramatic from late March through early May when snowmelt swells the stream. The hemlock forest provides dense shade and cool temperatures through summer, making this one of the few comfortable warm-weather hikes in the Delaware Water Gap area. The round-trip distance of 6.5 kilometers and elevation gain of 230 meters rates the trail as moderate, appropriate for fit beginners and families with older children comfortable on uneven terrain.
Sunfish Pond at the trail high point serves as a rewarding lunch stop with views across the glacial lake. No potable water is available on the trail; hikers should carry sufficient water from the trailhead. Restrooms are located at the I-80 Exit 1 information center adjacent to the parking area. The trailhead is one of the most popular in New Jersey and parking fills by 9 a.m. on spring weekends. No permits or entry fees are required within the Delaware Water Gap NRA.

- Extend the hike by turning north on the Appalachian Trail from Sunfish Pond for ridge views before returning the same way.
When to visit
Late March through May for peak waterfall flow and spring wildflowers in the hemlock gorge. October for fall foliage. Avoid summer weekends — the trailhead is among the most crowded in New Jersey due to proximity to I-80.
Accessibility
The Dunnfield Creek Trail involves rocky, rooted terrain and multiple creek crossings and is not accessible to wheelchair or stroller users.
