TRAIL MAPS:
Bunker Hill Natural Area - Township of Franklin
Griggstown Native Grassland Preserve Trail System - Township of Franklin  (Note that the purple trail is actually blazed with blue markers, it is not a lollipop with a loop, maybe a lollipop with several loops? and contrary to what the map says, dogs are not allowed but you don't see that until you are way over on the other side.)

Status of the trails at the time of this hike:
Bunker Hill Natural Area:
   yellow trail - all mowed and clear
   brown trail - all clear to Ten Mile Run
   blue trail - pretty much clear
   red trail - not cleared, not well-defined, overgrown, heavy blowdowns and thorny invasives
Griggstown Native Grassland Preserve System
   purple trail - which is actually blue, all clear
   brown trail - in the woods could not get through blowdowns heading out but was able to the other way from the orange trail
   yellow trail - all clear (sometimes also blazed orange instead of yellow)
   red trail - all mowed and clear but very soggy
   blue trail - did not hike much of it but looked to be mowed and cleared
   orange trail - mostly cleared, one section of heavy blowdowns

HIKE DISTANCE:  9.5 miles
To make the hike about half the distance, park at the Griggstown Native Grassland Preserve lot (40.435702, -74.609851) and hike those trails without going through the residential section over to Bunker Hill Natural Area. 

THE HIKE:

The trail starts as a wide, mowed path at the kiosk.

Just in case you might forget, you will see this sign very (VERY) often throughout the hike.

In case you forgot to wear your blaze orange...  or hike on Sunday when there is no hunting.

Starting on the yellow trail.

It was a pea soup foggy morning which actually made the hike more interesting.

The brown trail heads through the woods to...

... a rock hop ...

... to scenic shale cliffs at Ten Mile Run.  Retrace back to yellow from this point.  (The brown trail continues to another parking lot but most likely requires fording to cross Ten Mile Run since no rocks were visible.)

The blue trail in Bunker Hill Natural Area.

The red trail crosses Bunker Hill Road.

The red trail goes through a strip of woods between homes on either side.  The trail is not well-defined, not well-maintained, loaded with thorny invasives and blowdowns.

Then it appears as though the trail takes you into peoples' yards.  Continue between the two houses to...

The intersection straight ahead and follow the Greenway Trail signs along Winding Way.

Greenway?

When Winding Way veers to the left and the greenway signs are suddenly nowhere to be found, turn right on the paved road that turns to gravel after a large open area on the right ...

... and cross the bridge to ...

... this private park sign that you have to walk around to find

another Greenway Trail sign.

Follow the retaining wall of the private park around to this clearing on the right, turn right here and follow the faint path through the clearing (no blazes).

Rock hop over Simonson Brook (?)

After crossing the brook the trail in the clearing becomes the brown trai in Griggstown Preserve.

Looking back at the intersection of the brown and purple trails (but the purple trail is blazed in blue).

The purple trail that is blue.

Two benches at the end of the stick of the lollipop where blue splits - but there are more forks along the way all blazed in blue so it's hard to figure out what is what with no accurate map.

Having a snack before we were aware no dogs are allowed here.  There are no signs in this area. 

I figured out the blue trail was the same as the purple trail when I came across the Bunker Hill Environmental Center.

Then farther along at the kiosk at the building ahead a sign saying no dogs allowed and ...

... turn around to find one in the opposite directions.  So we skedaddled on out of there instead of trying to figure out the loops.

The brown trail merges onto a gravel road before it leaves to the right.  When it becomes a footpath I found it to be impenetrable because of the massive blowdowns - I could not find the continuation of the trail after bushwhacking around the largest so I went back to the gravel road and continued on yelloe.  I was able to stay with the brown trail later coming in the opposite direction.

When brown leaves the gravel road, it continues as yellow and yellow leaves into the woods as a footpath just before this large tank.

The yellow trail is sometimes blazed with yellow markers, sometimes orange.  There is an orange trail but that is a different trail.

The yellow trail comes out into a field as a mowed path before meeting up with the red trail.

Some unfinished breakfast on a trail post.

From the red trail, a view of the Sourland Mountains and the Delaware Water Gap.  But not today.

I saw something huge land in a tree and I know it wasn't a turkey vulture (I think it might have been a bald eagle by the size and the way it landed) but a turkey vulture is what I ended up honing in on although I did not know it until I got home and blew the picture up.

The Griggstown Preserve parking lot across the fields.

I did get a red-tailed hawk!

The orange trail has been cleared mostly - still one section about in the middle that was blocked by blowdowns but passable.

Simonson Brook from the orange trail.

Blowdowns on the brown trail.  I found it easier to follow the white hunting warnings than the brown trail markers.

The brown trail leaves the gravel road into the clearing at the blue (purple on map) trail.

Crossing back over the brook where the brown trail ends and the red Greenway Trail begins through ...

... the residential area in between the two houses into the woods.

I had intended to stay on red all the way back to the parking lot but immediately before joining yellow, just before the lot, an impenetrable blowdown.  Had to backtrack to blue then yellow to get around to the other side.

On the yellow trail at the other side of the trail blockage.

There were tons of birds on the yellow trail that weren't there earlier in the morning.
