Join a park interpreter at the Thoreau house replica for fun and informative learning about Henry David Thoreau’s life and his stay at Walden Pond. Please refer to a park trail map available at any of the kiosks for specific locations. On holidays and weekends, Walden Pond State Reservation often closes because of visitor capacity. Visitors are strongly encouraged to call the park headquarters (978-369-3254) and listen to the voice message before planning a trip or attending a program. Suitable for all ages.
