Known locally as “The Cranberry,” this geological remnant of a long-ago ice age was one of TNC’s first preserves in Pennsylvania.



Standing out in vivid contrast to the surrounding Pocono Mountains landscape, Tannersville Cranberry Bog provides a snapshot of colder times. Thousands of years ago, a large glacial lake occupied the space of what has since become a thick soup of peat moss.

Affectionately known locally as “The Cranberry,” Tannersville Cranberry Bog is ingrained in the local community and culture, inspiring wonder among students, educators, scientists, nature lovers and photographers who visit each year. Of special interest are some of North America’s most beautiful native orchids, including rose pogonia and the state-endangered heart-leaved twayblade.

While the ice and lake have long receded, the unique ecosystem that remains today serves as the southernmost low elevation boreal bog along the eastern seaboard. It represents an intricate transformation that took place over the millennia and would be impossible to replace if destroyed.

The Tannersville Cranberry Bog Preserve is one of TNC's first nature preserves in Pennsylvania. The preserve in managed in partnership with the Kettle Creek Environmental Education Center who provide educational opportunities for the local community.

Over the years, careful stewardship by TNC and partners including Kettle Creek Environmental Education Center, Pocono Township, the Pennsylvania Department of Conservation and Natural Resources and a local volunteer stewardship committee has yielded great returns as the bog soaks up rain and runoff like a giant sponge—cleansing water and controlling pollution throughout the Pocono Creek watershed.

Exploring Tannersville

Created by the action of glaciers thousands of years ago, the Tannersville Cranberry Bog is a 150-acre wetland and relict boreal bog affectionately known locally as “The Cranberry".

A t-shaped wooden boardwalk extends to the edge of a bog. In the background, tall green trees crowd down to the edge of a narrow body of water.
Delicate pink flowers bloom at the ends of thick leafy branches. The rough back of a tree is visible in the background.

A wide boardwalk made of narrow wooden slats stretches into the distance. Saplings and tall plants press into the sides of the boardwalk.
A still, open body of water in a wetland is edge by tall orange grasses. The tops of the trees visible in the background also show fall colors of red and gold.


  • Access

    Because of its fragile nature, the bog itself can be visited only during regularly scheduled walks conducted by the Monroe County Conservation District's Kettle Creek Environmental Education Center. Private walks are available for groups upon request; dogs are not allowed on the boardwalk trail.

    Public access is always permitted on the North Wood and the Fern Ridge trails. A donation to support management efforts is requested.

    PLEASE NOTE: when traveling to the preserve, please do not turn into the home at 107 Lavender Lane (at the corner of Lavender Lane and Cherry Lane Road). This is a private residence; please respect our neighbor's privacy.

  • Public Trails

    North Wood Trail

    This flat loop trail system passes along the edge of the wetland and through a mature hardwood forest dominated by oak trees.

    The shorter loop along the edge of the ridge offers a better view of the area and the longer loop passes through several areas of ever- green trees and through excellent wildlife habitat. In winter, these trails are good for cross-country skiing.

    Fern Ridge Trail

    This single loop trail rises slowly in the beginning through an oak hardwood forest. Then it follows an old road and eventually proceeds down a slight hill to run along the very edge of the bog with lots of wetland trees, shrubs and ferns including blueberry bushes, yellow birch and red maple trees.

    The Boardwalk Trail remains accessible by guided tour only; dogs are not allowed on the boardwalk trail. Learn more about regularly scheduled hikes by contacting the Kettle Creek Environmental Education Center at 570-629-3061.

  • What to See

    Plants: visitors will find plants such as calla lilies, gold thread and carnivorous sundew and pitcher plants, as well as native orchids such as rose pogonia and the state endangered heart-leaved twayblade. Other endangered plants include bog rosemary and Labrador tea. Shrubs such as leather leaf, sheep laurel and swamp azalea can also be found here.

    Animals: black bear, river otter, bobcat, beaver, porcupines, mink, wild turkey and snowshoe hare can be found here. Canada warbler, wood thrush, scarlet tanager, golden-winged warbler, eastern towhee and whip-poor-will have also been spoted at the preserve.

  • Citizen Science: iNaturalist

    We are creating a citizen science database of all kinds of life—from lichens to ants, mushrooms to plants, birds to mammals and everything in between for our preserves in Pennsylvania and Delaware.

    TNC's roots began with local citizens and scientists concerned about special places and species. That legacy continues today. Across our lands, we are utilizing iNaturalist—a digital platform that gives users an opportunity to share and discuss their findings.

    Of the 14 preserve projects in iNaturalist, nine have observations recorded; help us increase that number and our understanding of the species—good and bad, native as well as invasive—that can be found on TNC lands across the state. This information can also help guide and inform our conservation staff's management and monitoring decisions.
