Get outside of four wheels and skip the traffic! The Cross-Bay Ferry is a high speed ferry that connects downtown St. Pete to downtown Tampa via the calm waters of Tampa Bay. For just $8 each way ($5 for Seniors, Military and College Students, and $3 for ages 5-18), you'll embark on an approximately 50 minute journey over the water. Docks are located at St. Pete's Vinoy Basin in St. Pete and the The Florida Aquarium in Tampa.
