Between the barrier islands and the peninsula are several bodies of water, through which traverses a section of the Gulf Intracoastal Waterway. From north to south they are: St. Joseph Sound between the islands and Dunedin, Clearwater Harbor between Clearwater and Clearwater Beach, and Boca Ciega Bay in the southern third of the county. Connecting Clearwater Harbor to Boca Ciega Bay is a thin, approximately stretch of water known as The Narrows, which runs next to the town of Indian Shores.
