The Biltmore Gardens, designed by one of America's most well known landscape architects, Frederick Law Olmsted are well worth exploring. Guided walks are available during the spring, and you can learn first hand about the All America Rose Garden which features more than 250 varieties. The estate is also home to one of the country's first managed forests.
If you need a more first-hand experience when it comes to life in the late 19th century, then look no further than the River Bend Farm. Blacksmiths and woodworkers will share their crafts with you in a turn-of-the-century reenactment, and there's usually an old-school bluegrass band on hand.
Finally, don't skip the estate's winery: The eight-sample tasting is included with your admission.
