Hiking Buttermilk Falls County Park!

Buttermilk Falls Park

Buttermilk Falls Park

Welcome to Buttermilk Falls Park! Located in West Nyack, New York, the park features a scenic waterfall and two western views where on a clear day you can see up to 16,000 acres. The 75 acre Buttermilk Falls Park was purchased by Rockland County with additional acquisitions in 1981. 




Buttermilk Falls Park is location in a portion of the Palisades ridge north of the Sparkill Gap. The Palisades are located along the western shoreline of the Hudson River in southeastern New York and in north eastern New Jersey. Rocks found in the Palisades are known as diabase and were formed during the Triassic period around 200 million years ago.


Buttermilk Falls consists of a mixed-oak forest community including the following species among others:

White Oak

Chestnut Oak

Northern Red Oak

Tulip Tree

American Beech

Black Birch

Maple-leaved viburnum

Bluestem Grass

Buttermilk Falls County Park Trail Map

Welcome! Today, using the above trail map (taken from the Rockland County New York Website), we are going to explore some of the 75 acres that make up Buttermilk Falls Park! Along the way, we’ll see some cascades and check out some cool western views. The total hike is an estimated 1.2 miles. Ready? Let’s go!

Blue Trail Trailhead

From the parking lot we are going to head northeast on 0.9 of a mile blue blazed trail.

Entrance to the Blue Trail

Entrance to the Blue Trail

Entering the park on the blue trail, the path starts flat but we find it is deceiving as we start to climb.

Japanese Knotweed

But before we start any kind of climbing let’s take a quick scan of some of the flora that’s sprouting near the entrance. What’s this plant that sort of looks like little bamboo shoots sprouting up everywhere alongside the trail? It’s Japanese Knotweed, a obnoxious invasive plant which, once established, is generally there for good. Japanese Knotweed forms monocultures, excludes native plants and does not provide any benefit to wildlife.

Blue Trail Steps

Leaving the Japanese Knotweed for now the Blue Trail is taking us up some wooden steps.

However, we soon find that the steps end and now we must drudge up the hillside through a pleasant woodland. All around us is American Beech, Black Birch, Northern Red Oak and Chestnut Oak among other species of trees.



Taking another look at the flora coming up, what’s this 3 leaved spiked covered plant popping up all over the place? It’s Wineberry. Wineberry is native to Asia and is an established invasive plant in the United States.

Continuing on we start hearing the sound of water, a good sign as we must be approaching Buttermilk Falls!

Whew! After all that climbing (it wasn’t that bad) we have arrived at Buttermilk Falls. The stream comprising Buttermilk Falls is a Hackensack River Tributary and joins the Hackensack River just north of the Lake Tappan Reservoir.

Trout Lily Leaves

Trout Lily Leaves

Taking a look around the forest floor we spot the leaves of Trout Lily, a native woodland plant which blooms in early spring. And here you thought all we would be looking at is invasive plants! The “trout” in it’s name is said to come from its mottled leaves which are said to resemble wild trout.

Heading southeast on the blue trail we come to an open area on the trail with Eastern Red Cedar and occasional trap rock.

Blue Trail View 3

Blue Trail View 1


We have also come to the first of two view points. This view has us looking south towards New Jersey and west towards the Ramapo Mountains which are part of the NY NJ Highlands region. It is said that President Teddy Roosevelt rode horseback through this area stopping at this point for a view when he was in the area.

Orange Trail Trailhead

Continuing southeast on the blue trail we pass the .21 of a mile Orange Trail trail head.

Blue Trail Second Viewpoint 2

Blue Trail Second Viewpoint 2

Shortly after we pass the orange trail trail head we arrive at the second westerly viewpoint. What a beautiful day! From an ecological perspective we are currently in a traprock glade/rock outcrop surrounded by dry grass and forb-dominated species.

Dutchman Breeches

Dutchman Breeches

Leaving the second and last viewpoint we continue on the blue trail and pass a small but interesting plant known as Dutchman Breeches. Dutchman Breeches are a native to the eastern US. The flowers (which have since wilted) are said to look like old fashioned breeches hence its name.

Blue Trail Rock Seat

Tired? Want to take a seat? There is a seat carved out of the diabase to our left. Neat!

Blue Trail Trail end


After a series of switchbacks we have come to the end of the Blue trail at the intersection with the white trail. Turning right on the white trail we walk in a north west direction.

White Trail

The White Trail is turning into a pleasant peaceful walk on a wide woods road. As we walk we hear Black-Capped Chickadees, a Northern Flicker and a Hairy Woodpecker.

Old Car White Trail

What’s that up ahead? Someone long ago dumped an old car off of the White Trail.

Rock Wall White Trail

Rock Wall White Trail

Looking to our left we pass by an old rock wall which is a sure sign the land we are walking on was at one time farmland.

Boardwalk White Trail

Looking ahead we spot a boardwalk further down the White Trail.

Swamp White Trail

As we walk on it we come to a Red-Maple Swamp to our left. Red Maple (Acer Rubrum) are one of the most common maples found in the northeast and is a common tree in wetlands.

Just past the swamp we have reached the end of the White Trail at the parking lot where we started our hike. And that concludes our hike! I hope you enjoyed it and that it inspires you to visit Buttermilk Falls County Park for yourself!

Tenafly Nature Center & Lost Brook Preserve!

Tenafly Nature Center

The Tenafly Nature Center & Lost Brook Preserve  (TNC & LBP) is a beautiful estimated 380 acre preserve located in Tenafly, New Jersey. The preserve has the Montammy Country Club to the North, Route 9W and the Greenbrook Nature Sanctuary to the east and residential development to the west and south. In addition to featuring relaxing hiking trails, the preserve boasts a 3 acre waterbody known as Pfister’s Pond which attracts a multitude of wildlife.

Pfisters Pond

Outdoor wildlife exhibits include two Barred Owls and a Red-Tailed Hawk. These raptors were previously injured prior to coming to the nature center and cannot survive on their own in the wild. Other attractions include the the John A. Redfield Building which includes the Stephen Minkoff Memorial Library and indoor animal exhibits.

Tenafly Nature Center & Lost Brook Preserve

The land that was to become the TNC & LBP was sold in lots by 1874.  Over time, the land owners could not afford the taxes and the lots reverted back to the town.  The land was purchased from Tenafly by developers in the 1950’s.  In 1958, a plan to construct 225 houses was approved by Tenafly but the plan lapsed.  Developer Bernard Gray proposed building a million dollar country club in 1960 but later backed out.

In 1962, NY developer Norman Blankman proposed to build 300 homes and a golf course on the land.  Tenafly swapped 60 acres of land with Blankman in 1963 to consolidate his land and the boroughs.  The 60 acres became the Tenafly Nature Center. Soon after the consolidation, Blankman abandoned his original proposal and created a plan to develop 5 office buildings and a golf course. This development was rejected by Tenafly’s planning board.  After other development ideas came and went, Blankman sold the land to Centex Developers in August of 1973 for 9 million.  Centex proposed the construction of 1,780 houses, town homes and apartment complexes on the land.  The land, valued at around 8.5 million dollars, was condemned by Tenafly which wanted to purchase the property for preservation purposes.

Green Acres Land & Water Conservation Fund

Tenafly completed the purchase of the land in 1976 using Green Acres funding, bonds and donations from the public. The new preserve became known as the Lost Brook Preserve.  Tenafly Nature Center took over management of the Lost Brook Preserve in 2005 bringing the total acreage of TNC & LBP to 380 acres.

In 2009, the Bergen County board of chosen freeholders announced a $900,000 grant to the Borough of Tenafly to acquire once acre of land adjacent to the nature center.  The nature center’s intent is to let the land revert to forest via succession.  The acre is uphill of Pfister’s Pond whose streams drain into the Tenakill Brook, an important tributary of the Oradell Reservoir which is a source of drinking water for a large percentage of Bergen County.


An estimated 7 miles of blazed trails are waiting to be explored at the TNC & LBP.

Map of the Tenafly Nature Center

The picture above shows all the trails in the Tenafly Nature Center section of the preserve. Click here for a map that also includes trails found in the Lost Brook Preserve.  All trails are directly or indirectly accessible from the estimated .55 of a mile Main Trail which can be accessed from the parking lot of the Tenafly Nature Center.

Main Trail

The Main Trail is the unpaved continuation of Hudson Avenue which heads from the parking lot down to Route 9W. The yellow, white (De Filiipi) and Bischoff Trail are accessible to the north of the Main Trail and the Red Trail, Allison Trail and Little-Chism Trail are accessible to the south of the Main Trail. The Main Trail passes by the historic Lambier House (private property) where Lambier Brook dead ends to the south of the trail.  Beautiful viewpoints of the 3 acre Pfister’s Pond are visible to the north of the Main Trail. Wild Geranium grows along the side of the trail in springtime.

Yellow Trail Trailhead

The 1/3 of a mile interpretive Yellow Trail is the best introduction to the TNC & LBP. Numbered markers found throughout this trail match with this booklet providing excellent information on the flora & geology of the TNC & LBP including topics such as American Chestnut, New York Fern, Diabase Trap rock and much more.

Numbered Marker on interpretive yellow trail

At the end of the booklet there is a quiz to test your knowledge.  The yellow trail follows the western border of Pfister’s pond and features a 50 foot watchable wildlife viewing dock that extends out on the western border of Pfister’s Pond.

Watchable Wildlife Grant Site

The trail then heads east and south to rejoin the Main Trail in a loop fashion.

De Filippi (White Trail)

The eastern side of Pfister’s Pond is accessible via the .4 of a mile white trail (aka De Filippi) trail.  The white trail is accessible from the Main Trail or the western terminus of the Bischoff Trail. The trail traverses north near the eastern border of Pfister’s Pond passing the De De Filippi shelter on boardwalks before turning east and then turning south to connect either to the Bischoff Trail to the east or the Main Trail to the south.

Bischoff Trail

The 0.6 white/red blazed Bischoff trail is accessible from the White trail from the west or off the Main Trail near 9W. From the Main Trail, the Bischoff Trail heads north and passes over a stream draining a small pond.

Bischoff Trail Swamp

From here, the trail turns west and passes to the south of the pond and traverses near Montammy Country Club to the North and the historic (private) Lambier house to the south.

Lambier House

The Bischoff trail then terminates when it meets the white trail.

Red Trail Trailhead

The .3 of a mile Red Trail, accessible from the Main Trail, heads south before turning east and north paralleling the east brook as it empties Pfisters Pond on its way to the Tenakill Brook.

East Brook

Many wildflowers such as Spring Beauty, Dwarf Ginseng, Trout Lily, Canada Mayflower and others appear on this trail in the spring.  The purple trail trailhead is accessible to the east of the red trail. The red trail continues north and terminates into the Main Trail.

Purple Trail Trail Head

The .5 of a mile Purple Trail heads southeast from the Red Trail and crosses over the east brook and the Blue Spur (short .2 of a mile trail which leads to Highland Avenue).

Blue Spur Trailhead

Once past the blue spur trail, the purple trail continues southwest crossing over Lambier Brook before terminating into the Allison Trail.

Allison Trail

The yellow blazed 1.4 mile Allison Trail is accessible from the north via the Main Trail, the east and south via the Little-Chism Trail and the west from the purple trail. Heading southwest from the Main Trail the Allison Trail passes wetlands and interesting rock formations.

Massive Rock Formation Allison Trail

These formations are made up of rock known as diabase which was formed when molten lava cooled underground.  The trail then traverses southeast where it briefly follows the Little-Chism Trail.

Little-Chism Allison Trail

From here the trail  crosses the Green Brook before heading southwest once more paralleling the Green Brook to the west and its wetlands before terminating into the Little-Chism trail near East Clinton Avenue.

Allison Trail End Near East Clinton Avenue

An interesting trail that is accessible from the Allison Trail is the 0.6 of a mile orange blazed Haring Rock Trail.

Haring Rock Trail Trailhead

This trail traverses the western portion of the preserve. Heading south from the Allison Trail, the Haring Rock Trail travels in a meandering fashion passing wetlands to the east. The trail terminates at the Haring Rock.

Haring Rock

The Haring Rock is a glacial erratic named after a Dr. John J. Haring who made sick calls in the area around the turn of the century on horseback. Doctor Haring often stopped at this rock to rest. An interesting fact about this glacial erratic is that it was originally located east of its current position on top of traprock where the Jewish Community Center is located. When the Jewish Community Center was developed the rock was moved to its current location. It was discovered that the rock would not stay put in its original position and was instead cemented in place upside down. The Haring Rock Trail ends at this rock and the Seely Trail begins here.

Seely Trail Trailhead

The 0.3 yellow/orange blazed Seely Trail is accessible from the Haring Rock Trail & connects to the Little-Chism trail once it crosses Green Brook.

Green Brook Crossing Seely Trail

The short trail traverses near East Clinton Avenue in the southern boundary of the preserve.

Little-Chism Trailhead

At 2.1 miles, the red blazed Little-Chism Trail is the longest trail featured in the TNC & LBP.  The Little-Chism Trail is accessible from the Seely Trail in the south of the preserve near East Clinton Avenue, the Allison Trail in the southern boundary near Route 9W or from the north off of the Main Trail. Exploring the trail starting from the Seely Trail terminus, the trail heads east near wetlands and turns north briefly leaves the preserve and traverses next to Route 9W before heading back to the forest.

Little-Chism Trail by Route 9W

Continuing north, the trail crosses over Lost Brook where a dam is visible.

Lost Brook

The trail joins with the Allison Trail briefly after it crosses Green Brook near more wetlands.

Green Brook Little-Chism Trail

Both the Green Brook, Lost Brook are tributaries of the nearby Hudson River. The trail then passes the trail terminus for the short Sweet Gum Trail (which leads to the nearby members only Greenbrook Sanctuary to the east).

Sweet Gum Spur Trailend

The trail continues heading north crossing over two additional tributary streams before terminating at the Main Trail near Route 9W.
