Which Should You Visit?
Key Largo and Port Douglas both deliver exceptional underwater access, but their surface personalities couldn't be more different. Key Largo embeds you in authentic Florida Keys fishing culture, where locals still work the water and tiki bars serve grouper sandwiches to sunburned anglers. The diving here means mangrove channels, shipwrecks, and that distinct Caribbean-adjacent ecosystem where manatees drift past coral formations. Port Douglas operates as Queensland's polished gateway to the Great Barrier Reef, complete with resort infrastructure and tour operators who'll helicopter you to remote reef sections. The town itself balances beach sophistication with tropical accessibility—think waterfront restaurants serving barramundi, not fish shacks with plastic chairs. Your choice hinges on whether you want immersive local fishing culture with good diving, or premium reef access with resort-level comfort and dining.
