The U.S. Fish and Wildlife Service, which operates the south Georgia refuge, says the visitor center at its main east entrance will be open seven days a week through the end of June. The change is made annually to accommodate higher tourist traffic that begins in mid-winter.
The visitor center will go back to opening only five days a week when visitation tapers off during the hot summer months.
The Okefenokee National Wildlife Refuge covers 402,000 acres of federally protected land near the Georgia-Florida state line.
