Optional Excursion Belle Meade Plantation.
Travel back in time with a memorable visit to the historic Belle Meade Plantation! Enjoy a guided tour of the beautifully restored 1853 Greek Revival Mansion, where every room offers a glimpse into the elegance and charm of the Old South. After the tour, we will have time to stroll the picturesque estate grounds, explore the outbuildings, and wander along the peaceful walking trails. Then, treat we will treat our taste buds to a Southern lunch, a smooth bourbon tasting, and a complimentary wine tasting at their on-site winery—an ideal way to savor a little Southern hospitality.
