The VMFA is a great place to check out some art while you're in town! The museum is free (certain exhibits are paid tickets) and it also has a great outdoor area to hang out on a nice day. Their restaurant, Amuse, is very yummy as well!
A 100 acre park filled with gardens and animals (a nature center, farm animals you can feed, and wildlife habitats - including a black bear!) to explore. If you're traveling with kids, this is a great daytime activity. Pack a picnic to enjoy before walking around!
