Garden Grove is located along the eastern edge of Hernando County Airport and is dominated by US 41, the main road through the community.
Though they list their address as being Brooksville, Garden Grove is the headquarters of the Southwest Florida Water Management District which is across from The Trails of Rivard Golf and Country Club.
The main road through Garden Grove is U.S. 41, which runs southwest to northeast from Masaryktown through Brooksville, the Hernando County seat.
The CSX Brooksville Subdivision runs along the east side of the road, and contains a spur to the airport, which was revived when US 41 was widened.
Two other roads run from west to east; the first is County Road 574 (Spring Hill Drive), which runs along the northern border of Hernando County Airport before terminating at US 41.
