Harbour Island is situated adjacent to Downtown Tampa across the Garrison Channel. Nearby areas are Davis Islands and Channelside. The Tampa Convention Center is located across the Harbour Island Bridge and Channelside is just across Beneficial Drive, both within quick walking distance.
Today, the island consists of mostly private residential areas, including high-rise condos with views of the Hillsborough Bay and Downtown Tampa skyline, apartment complexes, houses, single-family homes and large homes, as well as a yacht club. The island has a Westin Hotel. Jackson's Bistro Bar & Sushi restaurant spans 20,000 sq. ft. and includes special event space, Sunday brunch, waterfront dining, and a Friday and Saturday nightclub. There are also smaller shops and cafes at the northernmost strip.
