A typical completion time for the Grand Loop drive is between 4-7 hours, depending on traffic and the number of stops made along the way. Although it is possible to complete the drive in one day, it might not be possible to cover all the attractions if visitors stop to explore hiking trails and boardwalks. A more leisurely and comprehensive experience can be obtained by breaking the tour into three sections and exploring each of the Upper Loop, western Lower Loop, and eastern Lower Loop on separate days.
