The suburb is bounded by Milne Road in the north, Golden Grove Road in the east and Montague Road in the south. The suburb's western boundary runs parallel with, but midway between, Kelly Road and Nelson Road.
Dry Creek runs along the eastern boundary of Modbury North and in flows to the creek are stored in the Kingfisher Wetlands Project, a water catchment area that has provided a habitat for birds, insects and lizards. It is a popular recreational space for walking, cycling, and exercising pets.
