Between July 1845 and September 1847, Henry David Thoreau kept a cabin on this glacial kettle pond, writing the book that reshaped how Americans understood wilderness and simplicity. Thoreau built his cabin on land owned by his friend and mentor Ralph Waldo Emerson on the north shore of this glacial kettle pond, lived there for two years and two months, and wrote Walden, or Life in the Woods from the journals he kept during and after his stay. I went to the woods because I wished to live deliberately, he wrote, to front only the essential facts of life, and see if I could not learn what it had to teach.
Walden was not widely read in Thoreau's lifetime; he died in 1862, largely unknown outside his Concord circle. But in the twentieth century the book became foundational to the American environmental movement — Gandhi, Martin Luther King Jr., and E.O. Wilson all cited it as transformative. The replica of the cabin, reconstructed near the parking area, is smaller than most visitors expect.
The pond itself is a state reservation; swimming is permitted. Look for the cairn near the cabin site where readers leave stones in tribute.
