Cruises from Jacksonville offer the perfect blend of beachfront and urban exploration. Get the best of a laid-back beach town and a buzzing city when you book a Carnival cruise from the beautiful port of Jacksonville, Florida. The Sunshine State’s largest city has a redeveloped and revitalized downtown, full of upbeat shopping and lively restaurants, bisected by the scenic St. Johns River and its Southbank Riverwalk. Jacksonville is a gateway to the islands of the Bahamas but you’ll also have 20 miles of sandy beach life and endless acres of wildlife parks to enjoy before you board your Carnival cruise from Jacksonville.
