Watchung Reservation Sierra Trail

The Sierra Trail winds through woods along the shores of Lake Surprise and through the Deserted Village of Feltville.

11.0 miles. Trail surface ranges from mild wide paths to roots and rock-filled trail.

Our two cents:

Get a long hike in with easy navigation (one blaze color and well-marked throughout) plus interesting bits like the Deserted Village of Feltsville, a cemetery, and Lake Surprise along the way.

The extensive trail system offers plenty of bail-out opportunities to cut the hike shorter. Considerable traffic noise in many areas. This is more of a take a stroll/jog, have a picnic, walk the dog kinda park.

The park’s site has info about the Village, including a PDF containing all of the interpretive signage at the site.

Bonus: Mostly no hunting – except for Tues & Thurs Oct 1 – mid-Feb and certain days during shotgun season, Jan – mid Feb.


On the park site or print ahead. Trail kiosks contain a brochure with a QR code to their online map.
