The Spiegel Grove Off Key Largo.

A Wreck Trek Passport Program spotlighting the Florida Keys Shipwreck Trail now awaits divers visiting the Keys.

Certified divers can explore the destination’s most appealing feature—a string of sunken vessels and artificial reefs—and be awarded for logging back-to-back wreck dives or dives on subsequent visits through Jan. 1, 2012.

Divers taking up the challenge receive an Official Florida Keys Wreck Trek logbook upon reserving trips with participating dive shops. The passport highlights nine shipwrecks from Key Largo to Key West including Spiegel Grove, Duane, Bibb, Eagle, Thunderbolt, Adolphus Busch Sr., Cayman Salvager, Joe’s Tug and Vandenberg, the Shipwreck Trail’s southernmost addition.

After one wreck dive in each district of the Keys is accomplished, divers receive a personalized collage of wrecks suitable for framing. Upon completing all nine wreck dives, qualifying divers are entered into a drawing for one of several grand prizes including dive equipment and dive-and-stay lodging packages.

Each wreck dive varies in skill level. Shops may ask divers to present a logbook or dive computer to be reviewed for air management skills and depth profiles from previous dives. Refresher courses are offered.
