Thoreau took the naturalist beliefs of Transcendentalism out of the realm of theory and into practice when he left the comforts of town and built a rustic cabin at Walden Pond. Now a state park, the glacial pond is surrounded by acres of forest preserved by the nonprofit Walden Woods project.
The site of Thoreau’s cabin is on the northeast side, marked by a cairn and signs. Parking costs $5.
