South Santa Rosa County comprises the area from Holley and Navarre in the east to Gulf Breeze at the western end of the Fairpoint Peninsula, and along U.S. Highway 98. A section of Santa Rosa Island, containing the unincorporated community of Navarre Beach, is also part of South Santa Rosa County. Major bodies of water including Santa Rosa Sound, Pensacola Bay and East Bay strongly influence the housing and life style of citizens in the southern part of the county. This fast-growing region serves primarily as "bedroom communities" for Pensacola to the west and Hurlburt Field, Fort Walton Beach, and Eglin Air Force Base to the east. The U.S. Navy presence is marked by Whiting Field, and NOLF Spencer Field.
