Iona runs along McGregor Boulevard between McGregor and Punta Rassa, bordered north by the Caloosahatchee and south by Summerlin Road. Around thirty-seven per cent of its housing sits empty at any given time, one of the highest seasonal rates in the county.
It also sits close to San Carlos Bay and the causeway, which put it among the harder-hit parts of this belt during Ian. The mix here runs from Gulf Harbour and the gated waterfront communities down to Bayside Estates and the manufactured-home stock, which is an unusually wide range for one area.
