Perhaps the most important pond in American history, Walden Pond is a metaphor as much as a reality…which has actually succumbed somewhat to modernity. It is still worth visiting, circumnavigating, splashing in, and reading more about.
It is amazingly close to Boston and Cambridge. 12 miles away, as I recall.

Don’t miss the other literary sites, graves, homes and such in the Concord/Lexington area.
