Sherwood Gardens, more commonly referred to as the Tulip Garden is one of the best destinations in Baltimore during the late spring. Thousands of tulips are on display in this residential park, with flowering trees and plenty of other flowers making for a breathtaking visit. Although you're not supposed to eat here, I've seen plenty of people with picnic baskets. When the tulips are in full bloom, look for handouts that list and label each of the displays. This is all free to the public, but parking might be a problem since it's right in the middle of a residential area.
