Duval Street bills itself as the longest street in the world, running clean from the Gulf of Mexico to the Atlantic. In truth you can stroll it in under an hour, but nobody in Key West lets a good boast go to waste.

The name carries a quiet joke. It honours William Duval, Florida's first territorial governor, who happened to be a teetotaler. He would find his namesake thoroughly lined with bars today, Sloppy Joe's among them, on what is now the island's main commercial drag.

Treasure hunters have a claim here too. On the six hundred block sits the Treasure Salvors Store, selling coins pulled from a Spanish galleon wrecked in 1622. Locals wear them as pendants, calling them Key West Dog Tags.

VoiceMap's self-guided audio tours walk this stretch end to end, threading Hemingway's old haunts, sunken treasure and a governor's ironic legacy into one continuous story.
