Scattered all along the channels of northern Pinellas county are islands known as spoil islands because they were created with the dredged materials (known as spoil) that were dug up when the intracoastal waterway and other local channels were dredged. These man-made islands became a perfect spot for boaters, birds, and other wildlife to enjoy and flourish. While some of them are protected wildlife habitats, most of them are open to visitors and can only be reached by boat. On many of these islands camping is permitted and they make a great weekend getaway spot for campers, especially during the cooler months. Phil Good Tours offers excursions to these islands for day trips, as well as shuttle service for campers who would like to stay overnight.
