Seriously one of the coolest historical tours we've ever had. I have been going here for the Montpelier Hunt Races since high school (shout out to the McClellans, the Bonds, Lucia Page, and Molly Seeley!) If you don't have time for a tour, it's worth a drive by.
Beautiful place to peruse some plants, grab lunch, ice cream, and a bottle of win (strongly recommend you purchase a bottle of Crose).
