The Botanical Gardens is immediately accessible off Interstate 74, and near Interstate 57 and Interstate 72.
More specific instructions follow.
This is the exit for Illinois Route 47, Mahomet and Gibson City. Unless you are familiar with the area, do not take Exit 174. Although you will see a sign for Lake of the Woods Park at Exit 174, the most direct route is to use the next exit, which is Exit 172. It is about seven miles to the Botanical Gardens from here. The Botanical Gardens is about a mile out of town just inside the west side of Lake of the Woods Park.
