Exploring Harts Brook Nature Preserve!

Hart's Brook Park & Preserve

Hart’s Brook Park & Preserve

Welcome to the Hart’s Brook Nature Preserve! The preserve features woodlands and wetlands, a master garden and hiking trails. Prior to becoming a preserve the property was known as the Gaisman Estate and was owned by the inventor of the famous Gillette safety razor blade Henry Gaisman. In 1957, Gaisman passed the title of the estate to the New York Archdiocese. In later years, Marion Woods Convent took ownership of 11.5 acres of the estate. The remaining acreage was purchased by the State of New York (who retains 50% ownership of the property) Westchester County and the Town of Greenburgh in 1999.

Virtual Hike

Harts Brook Nature Preserve Trail Map

Harts Brook Nature Preserve Trail Map

Welcome to our virtual hike! Today we are going to cross brooks, pass interesting rock outcroppings and walk around 2 miles on 5 different trails! Our guide will be the trail map shown above.

Red Trail Meadow

Red Trail Meadow

Ready to start? From the parking area, let’s head west briefly entering the forest on the red trail. Paralleling Ridge Road, the Red Trail leaves the forest and walks through an open meadow flanked by enormous Norway Spruce trees.

Norway Spruce Red Trail

Norway Spruce Red Trail

As we walk past the Norway Spruce trees we pass a spur of the red trail to our left which leads back to the parking lot. Deciduous wooded wetlands are appearing to our right as we leave the meadow and re-enter the woods. Wait! What’s that sound? Spring Peepers! Spring Peepers are a small frog common in wetlands and are among the first frogs to call out in early spring. Thus, Spring Peepers are a true harbinger of spring! Their Latin name (Pseudacris Crucifer) is named because of a dark cross which forms an “x” on the frog’s dorsa. Because of their size, Spring Peepers are difficult to locate and we do not see any today.

Green Trail Blaze

Continuing south we have come to the end of the red trail and are at an intersection with the green trail. According to our trail map we will come to a pond if we head east on the Green Trail.

Going to the Pond

Going to the Pond

Let’s go east on the green trail and check it out. After only a few minutes of walking we’ve found that we have left the green trail and are now on the yellow trail. The flora is quickly changing from deciduous forest to evergreens consisting of stately Eastern Hemlocks and Rosebay Rhododendron the closer we get to the pond.

Eastern Hemlock

Eastern Hemlock

The Hemlocks have an overall healthy appearance with very little die-back from the Hemlock Wooly Adelgid. The Hemlock Wooly Adelgid is an exotic pest from Asia 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.

Yellow Trail Bridge

Crossing a wooden bridge over Harts Brook we come to a bench overlooking the pond and its outflow dam.

The nesting boxes were placed here by the nearby Greenburgh Nature Center to provide nesting habitat for Wood Ducks.

Stone Warming House

Stone Warming House

As we continue walking on the yellow trial we pass an old stone warming house which was part of the original Gaisman Estate. Leaving the stone warming house, the yellow trail is taking us east back to a branch of the green trail.

Orange Trail

Blue Trail Stream Crossing


Heading east on the blue trail we find ourselves crossing a brook.

Pine Grove Blue Trail

Pine Grove Blue Trail

Passing close to private residences the blue trail turns northeast and slightly climbs through a grove of White Pine trees.

Blue Trail Seasonal View of Hartsdale Lake

Looking east we can see views of Hartsdale Lake  (part of Scarsdale Country Golf Club).

Blue Trail Asphalt Path

Blue Trail Asphalt Path

As we pass a spur of the blue trail on the left the trail now becomes an asphalt path as we come close to the Maple Avenue entrance to the preserve. From here we follow the blue trail west back to the orange trail.

We are now back at the Green Trail we left a while back. Let’s head north which will take us back to the yellow trail.

Master Gardening

Master Gardening

After only a short distance on the yellow trail we have just stepped out of the woods and are by the master garden area of the preserve. We are now back at the parking lot where we began. Thank you for joining me today on this virtual hike! I hope it has inspired you to check out Hartsbrook Nature Preserve for yourself!

Westchester County’s Cranberry Lake Preserve!

Welcome to Cranberry Lake Preserve!

Welcome to Westchester County’s Cranberry Lake Preserve! Cranberry Lake Preserve (CLP), purchased by Westchester County in 1967, contains 190 acres of deciduous woodland, wetlands, an old quarry, several bodies of water and old ruins.

In the early 1900’s the land that was to become CLP was an active quarry utilized for the construction of the nearby Kensico Dam which holds NYC drinking water.

Kensico Dam


Cranberry Lake Preserve Trail

Trails are open dawn to dusk.  Trail maps are available at a kiosk outside or you can click here for a digital version.

  • CLP features four blazed loop trails. All trails begin and end with blazes featuring the Westchester County Parks logo.  Periodic numbers appear on blazes occasionally which correspond to your current location on the trail map. These numbers are found on wooden posts. (Please note the numbers do not appear on the online version of the trail map)

All trails are accessible by either orange or white blaze connector trails.

To Nature Lodge

Many sections of CLP trails display signs which lead back to the Nature Lodge. Click here for a trail map!

Red Trail

Red Blaze

At 2.4 miles the red trail is the longest trail featured in CLP. The red trail follows CLP boundaries with the exception of the quarry.

Blue Trail

Blue Blaze

The Blue Trail loops around both Cranberry Lake and South Pond for a total distance of 1 mile.

Cranberry Lake

Cranberry Lake is a natural body of water formed around 18,000 years ago by glacier activity. The lake is fed by an underground spring.

Ground Pine

Ground Pine can be found growing along the Blue Trail.

Yellow Trail

Yellow Trail Trailhead

The Yellow trail traverses rocky upland and a section of Cranberry Lake.

Purple (History) Trail

Purple Trail Trailhead

The Purple Blazed History trail is a self guided trail which explores most of the preserve including the quarry. The self guided trailmap can be found by clicking here.

Exploring CLP

While CLP’s trails are open dusk to dawn, the nature lodge and its parking area are closed most days by 5PM. It is strongly recommended that you park in the designated parking area near Old Orchard Street if you plan on hiking past 5PM.

It is from the Old Orchard Street parking entrance that the below description starts out from on the way to explore CLP. Let’s go!

Eastern Chipmunk Cranberry Lake Preserve

From the parking area, walk up the road to the nature lodge.

Cranberry Lake Preserve Nature Lodge

Just to the west of the nature lodge is an interesting wetland with a dock.

Wetlands Near Nature Lodge

It was here that I saw this snake.

Head inside the nature lodge to check out the exhibits and pick up a trail map.

Inside Cranberry Lake Nature Lodge

From the nature lodge, head south to take the yellow trail down to an Orange connecting trail.

Here there is a sign advertising Cranberry Lake. The orange blazed connector trail leads to a jointly blazed yellow/blue trail with Cranberry Lake straight ahead.

Yellow Blue Blazed Trail near Cranberry Lake

Follow the Yellow/Blue blazed trail south with Cranberry Lake to your left.

Bent Bridge

Continuing south, take the Orange Blazed Connector trail which will appear to your left near a wooden boardwalk known as Bent Bridge.

View of fen from Bent Bridge

Bent Bridge provides a good opportunity to check out the fen located to the south of Cranberry Lake. In the summer, white water lilies appear on the water.

Stone Chamber

Leaving Bent Bridge, the Orange blazed connector trail leads to a man-made “cave” known as the Stone Chamber.

Looking outside from inside Stone Chamber

The ruins surrounding the stone chamber were the property of a farmer named Thomas Cunningham. The Stone Chamber is a very neat little man-made “cave” of sorts that is fun to explore.

Ruins outside Stone Chamber

From here, the orange blaze connector trail leads past more stone ruins to the Purple Trail (aka History Trail). The path here follows an old railroad which separates the fen from South Pond.

South Pond

You are sure to hear splashes in the warmer months of frogs jumping in the water as you walk by.

Head east on the Purple Trail to a bench strategically placed in front of a beautiful cascade.


It’s a good spot to rest and relax in a peaceful setting.

To Quarry

From the cascade, continue east on the Purple Trail following signs for the quarry.

Abandoned Tennis Court

An abandoned tennis court will appear to your right.

Quarry Pond

The tennis court was part of the Birchwood Swim club which used the Quarry Pond for Swimming.

Tulip Poplar & Milkweed Abandoned Tennis Court

Nature is slowly reclaiming the tennis court. Birchwood Swim Club was discontinued in 1997.

Fish Quarry Pond

Once past the quarry pond the purple trail heads past old railroad car wheels which were used to haul granite during the quarry operation.

Railroad Wheels

The Purple Trail continues heading north climbing over the rocky quarry.

Quarry Trail

The height here is an estimated 450 feet above sea level.


Derrick anchors which once held heavy quarry machinery are still fastened in the rocks along the trail.

Old Automobile on Purple Trail

From here, the trail starts to descend the quarry and heads west passing an old abandoned car.

Continuing north the Purple Trail comes across the remains of a stone cutting shed.

Stone Cutting Shed Ruins

After exploring this area, follow the Purple Trail south until it meets with the red trail. From here, take the red trail southwest with Cranberry Lake to your right. Continuing south, retrace your steps until you pass the cascade with the bench at an intersection with the Purple Trail that you previously took into the Quarry territory. Continuing south, the red trail passes South Pond to the West.

South Pond

South Pond is man-made and was created during quarry activities.

Bird Tower on South Pond

A Bird Observation tower appears to your left. This tower provides great views of South Pond.

Remains of Stone Crusher

The red trail passes near the remains of a stone crusher foundation. The stone crusher was capable of crushing up to 1000 cubic yards of gravel per day when the quarry was active.

Signs for NYC Watershed appear to east of the trail.

Hush Pond

From here, the red trail turns west and temporarily leaves CLP & enters White Plains watershed land and passes Hush Pond to the south.

Stone Wall by Red Trail

From Hush Pond, the red trail passes a couple of connector trails and turns north following an old stone wall delineating NYC watershed property from CLP. According to David Steinberg who wrote a description of Cranberry Lake Preserve in his book “Hiking the Road to Ruins” the lower, crude, sharper-tipped walls are of colonial origin and the larger, cut-stone flat-topped walls are NY DEP watershed boundaries dating from the 1960s.

Indian Pipe

It was here that I found Indian Pipe growing when I visited in June of 2012. Continue following the red trail north with the wall to your left until you reach your car.
