About Walden Pond State Reservation

May 15, 2015

Walden Pond was once home to the renowned author, Henry David Thoreau. Now part of the Commonwealth of Massachusetts’ Department of Conservation and Recreation (DCR) Forests and Parks system, Walden Pond State Reservation comprises 335 acres of protected open space, where visitors come to experience the pond that inspired Thoreau. They also come to hike, swim, fish, canoe/kayak, and cross country ski.

In 1845, Henry David Thoreau came to Walden Pond to live. He stayed for just over two years. He didn’t come to inspire a myth or a legend, or to create movements, or to make a name for himself. He came instead for the simplest of reasons: to live simply in nature and to discover what it could teach him.

In March of 1845, Thoreau began planning and building his one-room house. He moved in on July 4th of that year. He studied natural history, gardened, wrote in his journal, read, took long walks, and drafted his first book, A Week on the Concord and Merrimack Rivers, a story of a paddle trip taken with his brother in 1839. He also made the first accurate survey of the pond. By no means a hermit, he frequently walked to Concord village, entertained visitors at his house and hired himself out as a surveyor. In September of 1847, Thoreau completed his experiment in simplicity and returned to live in Concord.

Thoreau’s sojourn at Walden started a long tradition of people coming to the pond and its surrounding woods for inspiration and recreation. The emergence of Walden as a public park was in keeping with the belief that nature is meant to be enjoyed by people. Lamenting the deforestation that had taken place around Walden, Thoreau wrote, “I think that each town should have a park…a common possession forever, for instruction and recreation” in an 1859 journal entry.  ”All Walden wood might have been preserved for our park forever, with Walden in its midst.”

In 1922 the Emerson, Forbes, and Heywood families granted approximately 80 acres surrounding the pond to the Commonwealth of Massachusetts with the stipulation of “preserving the Walden of Emerson and Thoreau, its shores and nearby woodlands for the public who wish to enjoy the pond, that woods and nature, including bathing, boating, fishing and picnicking.” Middlesex County was given the responsibility for management of the reservation. In the summer of 1936, some 485,000 people visited Walden Pond, with Sunday crowds numbering as high as 25,000 visitors.

Today, it is estimated that approximately 700,000 people visit the reservation each year.  In an effort to balance public recreation with protection of these resources, the DCR established a ‘people capacity’ at the park to ensure a positive visitor experience and to maintain the integrity of the resources.

By the time the Commonwealth acquired the property in 1922, much of Walden’s forest had been cut down. The woods have since grown back, so that the vegetation resembles the hardwood and softwood mix of Thoreau’s day, including berry bushes, sumac, pitch pine, white pine, hickory, black birch, and oak. Stumps of some of the 400 white pines planted by Thoreau and Emerson, leveled by the great hurricane of 1938, used to be found above Thoreau’s house site.

Wildlife of Thoreau’s time can still be found here. Gray squirrels, chipmunks, and rabbits are common. Skunk, raccoon, and red fox are active at night, but can occasionally be seen shortly before sunset or after sunrise. Kingfishers, blackbirds, chickadees, blue herons, and red-tailed hawks can often be viewed flying among the trees or over the water. In the spring and fall, migratory ducks and geese pass overhead and land in nearby wetlands for food and rest. As noted by Thoreau, the pond “is not very fertile in fish. Its pickerel, though not very abundant, are its chief boast.” The pickerel disappeared around the turn of the century, and the pond is now stocked annually with trout. In addition, sunfish, yellow perch, and small-mouth bass compete for crayfish.

Walden Pond is a 102-foot kettle hole pond formed over 12,000 years ago when the last glacier to cover New England slowly melted away. It is Massachusetts’ deepest natural body of fresh water. As the glacier melted, large chunks of ice broke off and became surrounded with and covered by vast amounts of sand and gravel carried by streams flowing from the glacier. As the blocks melted, they left behind depressions that eventually filled with water. Because of this geological history, most kettle holes like Walden Pond have no streams flowing into or out of them.

A replica of Thoreau’s house, constructed in 1985, and the location of his modest accommodations are available for viewing by the public. Year-round interpretive programs and guided walks are offered. Visitors can enjoy the new state-of-the art visitor center to open in 2017, and drop into the Shop at Walden, run by the Thoreau Society.

The interpretive staff at Walden Pond State Reservation offers a wide array of programs for visitors. Children’s seasonal programs include nature crafts, story time, and the Junior Ranger series. Adult and family activities include poetry readings, tracking and walking programs, and Thoreau talks. Tour themes focus on the natural history of Walden Pond and Thoreau’s life and his impact on society. Accessible hiking and boating programs are scheduled in the spring and summer. When scheduled in advance, school and group tours are available.  Reservations may be made by calling 978-369-3254. Only service dogs are allowed, and there is no bike riding within park grounds (there are bike racks to lock your bike on arrival). Walden Pond is a carry-in, carry-out facility. Please don’t litter.
