Overview

The USS Spiegel Grove (LSD-32) is one of the largest artificial reefs in the world. Located off the coast of Key Largo, Florida, this massive 510-foot ship was intentionally sunk in 2002. After initially sinking prematurely and landing upside down, a hurricane in 2005 incredibly flipped the colossal wreck onto its starboard side, making it much easier to dive.

What you’ll see

The wreck is teeming with marine life that has colonized the structure:

  • Goliath Groupers
  • Barracudas
  • Horse-eye Jacks
  • Massive schools of silversides

The Dive Experience

Because of its depth (the top of the wreck is at about 18m, and the bottom rests at 40m) and the strong currents in the area, this dive is strictly for Advanced Open Water divers. Penetration of the wreck is possible, but should only be attempted by divers with specific Wreck Diver or Cave Diver certifications.

Getting There

Dozens of dive charters operate out of Key Largo and run daily trips to the Spiegel Grove, making it one of the most accessible world-class wrecks in the United States.
