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 remember that on warm days and holidays, Walden Pond 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. Don’t forget your sunscreen and/or insect repellent. Suitable for all ages.
