My GPS got all kinds of confused and took me across the Route 22 bridge into PA so might be a good idea to take the brochure directions along.

THE HIKE:

Take the blue-blazed Warren Highlands Trail at the chain.  There is no way to walk around so you have to crawl under the chain.

It starts out as a rutted road...

... then follows an overgrown gas pipeline.

The trail gets better once it leaves the pipeline and enters the woods.

Ah, finally, some real trail!

Views of the Delaware River are very limited in the summer but in the winter there should be a decent stretch of trail with river views.

The trail continues uphill.

The orange-blazed Fulmer Mine Trail.

Stone work on the Fulmer mine trail that, according to the brochure, was possibly a former mine or shelter.

Fulmer Mine or the "Ice Caves."

Back on the Warren Highlands Trail through a rhododendron thicket.

Found one bloom that wasn't completely shot yet but we did miss full bloom which would have probably been end of June/early July.

The yellow-blazed Marble Hill Road Access Trail.

This trail crosses over some washouts and a small creek.

The red-square-on-yellow trail (not on the map) connects back to the blue-blazed Highlands Trail.

A large old growth tree.

A power cut ...

... with a nice view west into Pennsylvania.

Finding this on the trail creeped me out - HATE HATE HATE knives!  No way was I carrying it with me to dispose of it and it was all moldy and disgusting so I flung it into the woods in hopes nobody will ever find it again.

The trail becomes overgrown again...

... as it follows along a corn field.

Just around this right turn...

unexpected views of the countryside.

It was cool and cloudy so it made a nice break spot.

Farther downhill from the corn fields, some old stone ruins.

The trail follows the farm road.

Where the trail leaves the farm road it becomes very overgrown but it only leads down to Belvidere Road in a short distance so this was our turn around point.

Heading back uphill through the farm.

Back in the woods, a Merrill Creek Reservoir sign.

The red-blazed Lopatcong Municipal Park Access Trail.  Dogs are not allowed in that park, the reason we did not park there.

The Delaware River view, which is not a view at all in the summer with foliage in the way.

A little bit of the Delaware River on the right.

I had noticed this sign down on River Road so I left the trail and road walked a short distance to see what it was but unless you have an appointment, there is nothing to see.  All gated and locked up.

Just a short distance back to the car on River Road but it bypassed the overgrown gas pipeline part.

From the parking area I saw a large bird land on the fence way over at the other side of the Aqua New Jersey property so I zoomed in to see what it was.

He took off again after just a minute or two.

This one stayed behind.
