US Route 604

Warren County, NJ


US Route 80 west to Exit 25; turn at the first right onto the exit for the International Trade Center; drive .7 of a mile and turn right onto Continental Drive North; drive 1.1 miles and turn left onto Route 604 south; drive 4.2 miles and turn left into Saxton Falls parking area.


The Musconetcong River Valley narrows to less than one-eighth of a mile at Saxton Falls, south of which its opens back up, this time to one to two miles.  (Wacker 1968:4)


By Saxon Falls the lock lifted the boats to higher ground on the North Side of the road. This is Guard Lock 5.

A dam was erected here in 1830 as a feeder for the 30.6 miles stretch from here to the Delaware River (Phillipsburg). An average of 34.17 cubic feet per second of water was drawn from storage in Lake Hopatcong, Cranberry Lake, and Bear Pond. The property and 3.33 miles of right away was bought from Nathaniel Saxton.

A new dam was erected here in 1927 under Governor A. Harry Moore. The President of the corporation was Howard F. McConnell.


10/25/00 Michael St. John and I took a walk north along the Musconetcong River from Saxton Falls. We passed a boarded up house by the river with "The Brackmanns" printed on it.
Walking along the river we noticed that there must have been a cutting crew that had recently came through the area. As usual with cutting crews, they had no concern about botany or vegetation and indiscriminately cut everything down, including beautiful Iris species and swamp rose.

We could not walk very far (maybe 15 minutes) because there was a big water-filled gap in the causeway connecting the river with the former canal bed. There is a nearby house and they had an illegal wire fence blocking off foot traffic from access to the river. When the cutting crew came through they probably threw the fence aside. We speculated that to get even with the cutting crews, the house owners removed the board that undoubtedly was here and that once spanned the water-filled gap in the causeway. We thought the house-owners probably threw the board into the river. We had a laugh-filled lunch by the dam at Saxton Falls, because there in the water, caught on the rocks below the falls, was the board (with the anchoring bolt still attached) that the angry home-owners probably threw into the river. We speculated that this type of vandalism was probably self-defeating because it will cause hikers to delay around the water gap while figuring out how to get over the gap, thereby spending more time around the house property.

Brian Morrell has a website on the Morris Canal Trail and he says that you can take the Saxon Falls Mine Trail. By Saxon Falls the lock lifted the boats to higher ground on the North Side of the road.

Following the towpath east, you can cross over the canal by using a tree as a "natural bridge" . Climbing to the top, you can see a number of mine shafts. One was over 35 feet deep and 15 feet across.

The Highlands Trail route will proceed from Route 15 to the Sussex Branch Trail, which it will follow to Allamuchy State Park. From Allamuchy State Park, two potential routes diverge. The Hunterdon Highlands route heads south through Saxton Falls to Schooley's Mountain, which it follows to Voorhees State Park and Spruce Run Reservoir. From there it follows Musconetcong Mountain to the Delaware River near Riegelsville. The Warren Highlands route heads west to Jenny Jump Mountain, which it follows south to Buttzville and Oxford Furnace. Then it picks up Scotts Mountain and Marble Mountain to complete the trip to the Delaware River at Phillipsburg.
