You can also explore the Pioneer Farm a five-acre site where Washington's progressive farming practices came to life and walk among the English-style garden and grounds. Be sure to pay homage to the president and first lady at the Washington Tomb.At your prebooked time, head to the mansion, an iconic, red-roofed residence that began as a modest farmhouse in 1735.
