Fodor's Expert Review Marsh-Billings-Rockefeller National Historical Park

Vermont's only national park is the nation's first to focus on conserving natural resources. The pristine 555-acre spread includes the mansion, gardens, and carriage roads of Frederick H. Billings (1823–90), a financier and the president of the Northern Pacific Railway. The entire property was the gift of Laurance S. Rockefeller (1910–2004), who lived here with his wife, Mary (Billings's granddaughter). You can learn more at the visitor center, tour the residential complex with a guide every hour on the hour, and explore the 20 miles of trails and old carriage roads that climb Mt. Tom.
