Welcome to Campgaw Mountain Reservation!

Campgaw County Reservation Map

Campgaw County Reservation Map

Covering about 1,300 acres, Campgaw Mountain is part of the Bergen County Park System. The park is located in both Mahwah and Franklin Lakes New Jersey.


Basalt Hemlock Trail


Despite its close proximity to the Ramapo Mountains which are comprised of Highlands “basement” rocks, Campgaw Mountain comes from a different geological background.  With a ridge expanding two miles Campgaw Mountain is comprised of basalt and is part of the Watchung Mountains. Elevations range from 300 feet to a maximum elevation of 751 feet atop Campgaw Mountain.


Campgaw Mountain Reservation Ecology


Campgaw Mountain contains several ecological communities including upland xeric (dry) deciduous forest, mesic (moist) deciduous forest and deciduous forest wetlands. Meadow habitat can be found along the power lines within the boundaries of the park.

The below are a sample of a list of birds that have been spotted within Campgaw Mountain:

Campgaw Mountain Trail Lengths

Welcome! Today we are going to see eastern views near a ski lift, and explore an interesting pond! Ready? Let’s go!



Let’s start our journey by heading west on the joint .5 of a mile Yellow Blazed Indian Trail and Blue Blazed .90 of a mile Rocky Ridge trail.

Rocky Ridge Powerline Cut

Rocky Ridge Powerline Cut


Almost immediately the blue blazed rocky ridge trail splits off from the yellow blazed Indian Trail. Let’s take it! We’ll meet up again with the Indian Trail later. On the Rocky Ridge Trail we pass under power lines between two old buildings.

Old Cedar Trail 1

Old Cedar Trail 1

As we walk we go through an intersection with the 2.10 mile Red Blazed Old Cedar Trail.

Skunk Cabbage

Continuing on the blue blazed Rocky Ridge Trail we pass over Fyke Brook (a tributary of the nearby Ramapo River which in itself is a tribute to the Passaic River) and wetlands filled with blooming Skunk Cabbage to our left.

Blue and Green


Soon we pass the green blazed .30 of a mile Beeches trail to our right.

Old Machinery Blue Trail 2

Old Machinery Blue Trail 2

Continuing on and Looking to our right we pass the ruins of some sort of machinery. As we walk, we see some Mourning Doves, and hear both a Northern Flicker and a Blue Jay.

Japanese Barberry Rocky Ridge Trail

Japanese Barberry Rocky Ridge Trail

The Rocky Ridge footpath has now changed to a gravel road which we are climbing. Looking to the sides of the trail we see lots of Japanese Barberry, which has become an established invasive plant in the understory of the forest of Campgaw Mountain.

Old Cedar Trail

Old Cedar Trail

As we near the top of our climb the Rocky Ridge Trail has left the gravel road and is now a rocky footpath traveling along the ridge of Campgaw Mountain (hence the trail’s name!) We pass through another intersection with the 2.10 mile Old Cedar trail.

Basalt Rocky Ridge

Basalt Rocky Ridge

Turning north on the Rocky Ridge Trail we find the landscape has become even more rocky but pleasant and more open like the environment found among the ridges of nearby High Mountain Park Preserve with basalt appearing now and then.

Dutchman Breeches Rocky Ridge Trail

Dutchman Breeches Rocky Ridge Trail

As we walk on the basalt of Campgaw Mountain, we spot some Dutchman Breeches along with some Hepatica flowers growing to the side of the trail. Dutchman Breeches are named as such because the flowers resembles old-fashioned breeches. Hepatica flowers are named as such because the leaves are said to resemble liver. Both are ephemeral flowers found only in the early spring before the leaves on the trees come back. As we admire the flowers we hear a Red-Tailed Hawk screech overhead.

Shagbark Hickory and Eastern Red Cedar Blue Trail

Shagbark Hickory and Eastern Red Cedar

Looking at some of the trees as we walk we pass by Shagbark Hickory and Eastern Red Cedar. We have now arrived in an open woodland. We spot Wineberry, a common invasive plant from Asia sprouting from the forest floor. As we walk we pass several structures for Frisbee golf (aka disc golf) which is set up throughout the park.

Rocky Ridge Trail End

Arriving near the ski lefts the .50 of a mile yellow blazed Indian Trail we left when we first started reappears.

Eastern View 5 with Ski Lifts

Take a look at the view! Here we can see a clear eastern view of surrounding Bergen County.

Indian Trail

Leaving the the Rocky Ridge Trail, we now head east on the yellow blazed Indian Trail and pass the green blazed beeches trail to our left and right.

Skunk Cabbage Wetlands

Skunk Cabbage Wetlands

Looking to our left we spot a good amount of Skunk Cabbage as we go down the Indian Trail. Ahead of us is a swamp. Many people think that any wetland they may see is a swamp but this is not the case. A swamp contains woody vegetation whereas marshes do not.

Hemlock Trail

Hemlock Trail

From the Indian Trail we turn left on the orange blazed Hemlock Trail. The Hemlock Trail follows along the shore of Fyke Pond which was created from the impoundment of Fyke Brook.

Fyke Lake

Fyke Lake

As we walk along we pass several smooth bark grey trees. These are American Beech, a slow growing native deciduous tree of the eastern forest.

American Beech Hemlock Trail

Continuing on we pass to our left two massive boulders made of basalt.

Basalt Boulders Hemlock Trail

Basalt Boulders Hemlock Trail

As we pass the boulders a sudden cry pierces the ear: a Blue Jay has noticed our presence and is sounding the alarm that we are in its forest.

Blue Jay

Blue Jay

As we walk we pass by many dead and dying trees from which this trail was named after: The Eastern Hemlock. Most of the hemlocks found in Campgaw Mountain County Reserve are dead or dying due to the Hemlock Wooly Adelgid.  Native to East Asia, the adelgid feeds by sucking sap from Hemlock trees.  This exotic pest was accidently introduced to North America circa 1924 and is currently established in eleven states ranging from Georgia to Massachusetts. It is estimated that 50% of the geographical range of the Eastern Hemlock has been affected by the adelgid. Biological control (i.e. using adelgid predators to control infestations) has been the major emphasis of control since 1997.

Dying Hemlock

Morris County’s Great Swamp Outdoor Education Center!

Morris County Park Commission Great Swamp Outdoor Education Center (with Common Reed)

Welcome to Morris County’s Great Swamp Outdoor Education Center!

Great Swamp Outdoor Education Center

The Great Swamp Outdoor Education Center (GSOEC) consists of a 44 acre portion of the Great Swamp managed since 1963 by the Morris County Parks Department. The GSOEC hosts guided nature walks, school, scout and public educational programs.

Herp Study in Progress

The GSOEC hosts periodic studies of the flora and fauna to determine the overall health of the Great Swamp.

Great Swamp National Wildlife Refuge

The estimated 7,768 acre Great Swamp National Wildlife Refuge  (GSNWR) abuts the GSOEC to the west. The GSNWR is one of 553 refuges administered by the Department of the Interior’s U.S. Fish and Wildlife Service. Lands comprising a National Wildlife Refuge are managed for the protection of wildlife and its habitat.

History of the Great Swamp

The origin of the Great Swamp begins with the melting and subsequent retreat of the Wisconsin Glacier around 25,000 years ago.  Debris from the glacier blocked the passage of an ancient river creating an enormous lake known as Lake Passaic. Lake Passaic is thought to have been 30 miles long and 10 miles wide.  Over time, an outlet was formed near Little Falls NJ draining the lake via the Passaic River. This drainage is still occurring today. Today the Great Swamp forms a remnant component of the once great Lake Passaic.

GSOEC Forest

In the late 1950’s the area now known as the Great Swamp was identified by the NYNJ Port Authority as an ideal location for a new jetport.  The Great Swamp Conservation Foundation mobilized volunteers to protect the Great Swamp. The result was the establishment of the Great Swamp National Wildlife Refuge. The Great Swamp Conservation Foundation later became the North Jersey Conservation Foundation and then finally known as  New Jersey Conservation Foundation.


GSOEC features four short loop trails. Two of the four trails (Orange & Red) are interpretive and follow 16 markers listed in a self guided trail booklet available at the education center. Click here for a trail map!

The total length of the trails is 1.4 miles.

Virtual Tour:

Ready to take a virtual tour of the Great Swamp Outdoor Education Center? Let’s Go!

Stop by the kiosk near the parking lot to pick up a trail map. From the kiosk, head to the education center to view the exhibits on the flora and fauna of the Great Swamp.

Outdoor Education Nature Center with Kiosk

Mammals of The Great Swamp

Endangered in New Jersey

After checking out the exhibits inside, it’s time to start our hike.

Orange Trail Trailhead

Let’s begin our virtual hike by taking the Orange Blazed trail located to the south of the education center. The Orange Trail at .61 Miles is the longest trail present in the GSOEC. It contains Markers 1-10 from the self guided trail.

Marker 1

The first marker, regarding the Red Maple tree, appears shortly after the beginning of the orange trail. Red Maple is the most common tree in the Great Swamp as well as the eastern deciduous forest.

Red Maple Leaves

Red Maple’s flowers are red in the spring and the leaves turn a brilliant red in the fall. Though the Sugar Maple may come to mind when it comes to maple syrup, Red Maple can be tapped for syrup as well. Red Maple should be tapped before budding occurs as the buds change the chemical makeup of the syrup.

Marker 2

Continuing on the orange trail, marker #2 comes into view on the right where a large depression may be found.

Large Depression

The large depression is known as a vernal pond. Vernal ponds do not support fish and may be dry or filled with water. Due to the lack of predators (i.e. fish) the vernal pond provides a safe haven for amphibians such as Wood Frogs, Spring Peepers and Blue-Spotted Salamanders among other species to breed and lay eggs.  Continuing past the vernal pond, two fenced areas appear shortly after on the left.

Marker 3 with Deer Enclosure in background

Marker # 3 explains that these sections of the GSOEC were fenced in 2009 to study how plant communities recover from the damage caused by an overpopulation of white tail deer.

Marker 4 EcoTone

Marker #4 describes an Ecotone. An Ecotone is anywhere two habitats meet and create an edge. The Ecotone present here was created by the Power line right of way. The positive aspects of this man-made Ecotone is  the creation of suitable nesting habitat for the local turtle population in addition to providing a valuable hunting ground for birds of prey. On the flipside, the disturbed ground caused by the creation of the power lines have provided ideal habitat for invasive plants  as Autumn Olive, Multiflora Rose, Garlic Mustard, Wineberry & Japanese Barberry.

Marker 5 The Pond

Continuing in a southwest direction, the dirt path changes to a boardwalk as the trail traverses the wetland area.

Orange Trail Boardwalk

A short boardwalk appears to the right of the main boardwalk which leads to the Pond which is marker #5.

The Pond

Ponds are usually less than 18 feet deep. Eventually as plant matter and other organic material decays, the pond will begin to become a marsh, progress to a forested wetland and finally upland habitat after many years.

Painted Turtles on the Pond

The Pond at GSOEC is manmade and provides habitat for Eastern Painted Turtles, Snapping Turtles, Wood Ducks, Mallards, Belted Kingfisher and River Otters among others. Flora of the Pond includes Yellow Flowered Spatterdock & Duckweed.

Poison Ivy

Continuing on the trail leads to Marker #6 which describes Poison Ivy which is seen here growing as a hairy vine.  Poison ivy contains a clear liquid known as urushiol which causing a burning itching rash in many people.   In addition to a hairy vine Poison Ivy can be found as a shrub reaching over three feet tall or as a trailing vine on the ground.

Several rhymes exist warning of the dangers of Poison Ivy:

“Leaves of three, let them be”

“Hairy rope, don’t be a dope”

“Hairy vine, no friend of mine”

Common plants often misidentified as Poison Ivy include Virginia Creeper and Box Elder Maple among other species.

Despite the negative publicity this native plant receives, Poison Ivy has tremendous value for wildlife.  Native birds such as Eastern Bluebird, Gray Catbird, Dark Eyed Junco and Northern Flicker eat Poison Ivy’s white berries. Mammals such as White-Tail Deer and Eastern Cottontail consume Poison Ivy’s leaves.

Mountain Laurel

At this point of the hike you may notice abundant Mountain Laurel. Marker # 7 appears here.

Marker 7 The Browse Line

Its purpose is to briefly touch upon “the browse line”. The over abundant white- tail deer have stripped all leaves of vegetation from six feet down. If the current trend continues, there may not be a forest here in the future.

From this area, the trail head of the .23 of a mile Blue trail loop appears.

Blue Trail Trailhead

Let’s take a brief break from the interpretive trail to explore this short trail.

Blue Blaze Swamp Chestnut Oak

The Blue Trail Loop goes through an upland area consisting of mostly Mountain Laurel and Swamp Chestnut Oak.

Dried Vernal Pond Blue Trail

The trail encircles a small vernal pond (the vernal pond, seen here at the end of September 2012 was dry).

Blue Trail trailend

Completing the Blue Trail Loop, head back to the Orange Trail and to Marker # 8 which describes the function of a rotting log in the forest.

Rotting Log

Standing dead trees or snags play an important role in the eastern deciduous forest. Woodpeckers including Pileated, Downy and Red-Bellied among others excavate holes in the dead trees searching for tasty insects. These excavated holes in turn create habitat for birds including Black-Capped Chickadee. Fungus will usually invade the dead wood further softening it. Eventually, the tree will fall to the forest floor where it will continue to decay creating a rich organic soil which will support future species of trees.

Marker 9 Phragmites Marsh

Proceed  east  to Marker # 9 The Phragmites Marsh. Phragmites (aka Giant Reed) is a giant species of grass which can grow from 10-20 feet.  Phragmites thrives in disturbed areas. Phragmites found in the Great Swamp are native to the eastern deciduous forest. Phragmites are considered invasive because of its aggressive growth and tendency to overwhelm all other vegetation.

Marker 10

Outdoor Study Area

From here the trail leaves the boardwalk and heads south to marker # 10 which passes an outdoor study area and leads to a Wigwam replica.


The Lenape Native Americans (the original people) created Wigwams as shelter from saplings, tree bark and Cattail Mats among others. This replica would have been big enough for two people. Marker #10 is the last marker for the orange trail.

Orange Trail Trailend

After heading back from the Wigwam, turn right on the Orange Trail and follow the trail a brief distance to its terminus.

Prayer of the Woods

The “Prayer of the Woods” sign is found right before the start of the Red Trail. After reading the Prayer and taking in its message, turn right to start hiking the .39 mile Red Trail to continue the interpretive trail.

Red Trail Trailhead

The first marker on the Red Trail is #11 which identifies trees found in the Eastern Deciduous Forest.

Marker 11 Deciduous Forest

Trees found in the Eastern Deciduous Forest include the below among others:


Black Oak

Pin Oak



The term “deciduous” indicates that the trees comprising this type of forest lose their leaves each fall and grow new leaves in the spring.

Marker 12 Transmission Lines and Marsh

Continuing on the red trail leads Marker #12 “Transmission Lines and Marsh”.

Red Trail Power Cut

Here, vegetation is periodically removed or trimmed back so as to not interfere with the power lines. This wet marsh provides habitat to Wood Ducks, Mallards, Muskrats and Red-Wing Blackbirds among others.

Red Trail to Education Center

From here turn left at the sign leading to the education center to go to Marker # 13.

Marker 13 Stream

The Red Trail approaches Marker #13 as it crosses a stream.

Red Trail Stream Crossing

Sediments and rocks on the stream bottom provides habitat for a variety of Crayfish and Macro-invertebrates. Marco-invertebrates lack backbones and can be seen without the aid of a microscope.  Certain macro-invertebrates such as Caddisflies are pollutant intolerant. Presence of pollutant intolerant macro-invertebrates are one way to indicate the health of a stream. Macro- invertebrates eat many different things depending on the species-there are predators, scavengers, and herbivores among them. In turn, macro-invertebrates are a source of food for various turtles, fish and frogs.

Marker #14 The Wet Meadow

Continuing on the red trail leads to Marker #14 which discusses“The Wet Meadow”. The Wet Meadow is a man-made habitat created by a power-line cut and is home to field mice, star-nosed moles and various hawks & owls among others.

Marker #15 American Beech

Marker #15 leads to an American Beech Tree. The smooth gray bark of the American Beech Tree usually invites individuals to carve their names and other messages into the trunks. Carving in a tree trunk is similar to a cut on your finger. However, unlike your injured finger, a tree cannot put a band-aid on its wound. The carved bark is an open door for disease.


Beechdrops, seen here in this picture, lack both leaves and chlorophyll and is a parasitic plant of the American Beech Tree.

#16 The Swamp

Marker #16 The Swamp

The final marker on the red trail briefly discusses the importance of the Great Swamp. The land comprising the Great Swamp is a mix of meadows, upland woods, marsh and brush covered swamps. Only 40% of the Great Swamp is wet either part of the year or all year long whereas 60% of the Great Swamp  consists of upland forest & meadows.

Red Trail End

You are now at the end of the Red Trail.

Green Trail Blaze

At the end of the red trail head north to catch the beginning of the short .20 of a mile Green Trail near the parking area. The Green trail traverses in a short loop in an upland portion of the GSOEC.

Mushrooms Green Trail

Check out these mushrooms found growing in September 2012!

Asian Long Horn Beetle Detector

In the parking area near the end of the Green Trail you may notice a black box hanging from a tree. The Black boxes are used to detect for the presence of the Asian Long-Horn Beetle, an invasive species from Asia.

Wildlife Blind

After the Green Trail is complete, it’s time to visit the Observation Blind located off the parking lot which views the Pond looking west.

Turtles on the Pond from Wildlife Blind

This concludes our virtual hike! I hope you enjoyed it and it inspired you to take a trip to see the GSOEC for yourself!
