What is Spiegel Grove?
Spiegel Grove is a shipwreck at Key Largo, Florida, that was originally a US Navy Thomaston-class dock landing ship. The vessel, named for President Rutherford B. Hayes’ house, had a noteworthy service history before being transformed into an artificial reef. The ship was deliberately sunk in 2002, as planned by the state of Florida. The ship unexpectedly sank too quick during the sinking operation. As a result, it wound up on the ocean floor inverted, with the bow visible above the water. Hurricane Dennis, however, corrected this in 2005 by flipping the vessel to its intended position. The Spiegel Grove wreck has a depth range of 70 to 130 feet (21 to 40 meters), making it an intriguing dive within the Florida Keys National Marine Sanctuary.
History of Spiegel Grove
The USS Spiegel Grove’s operational life centered mostly around tactical operations off the east coast and in the Caribbean. The ship took part in several major tasks, including “Solant Amity II,” a goodwill mission transporting relief supplies along the African coast, and “Operation Steel Pike I” off the coast of Spain. It also aided the Mercury-Atlas 7 manned space flight. Spiegel Grove was decommissioned and placed in the James River “mothball” fleet in 1989.
The USS Spiegel Grove was turned into an artificial reef off the coast of Key Largo, Florida, in 2002, after a thorough cleaning and deliberate preparation for safe diving access. The ship was sunk by allowing water into her ballast tanks, but an unexpected premature sinking caused her to capsize. Despite the fact that she was lying on her starboard side, marine life began to colonize the structure, with corals, barnacles, sponges, and fish transforming it into a thriving ecosystem.
In an unexpected twist of fate, Hurricane Dennis in 2005 rolled the Spiegel Grove back into its proper upright position. Today, this thriving artificial reef is home to a big variety of marine species and serves as a unique and popular dive site, contributing to ocean conservation efforts and bolstering the local tourism industry.
Diving into Spiegel Grove
The USS Spiegel Grove lies six miles off the Florida Keys, on Dixie Shoal. As it is six miles off the coast, you can only access it by boat. The wreck is located inside the Florida Keys National Marine Sanctuary, with the wreck’s top deck approximately 60 feet beneath the water’s surface, while its expansive hull reaches depths of 135 feet. The dive site is not suitable for beginner divers, and only divers holding an advanced certification (or higher) can dive the site.

The sheer magnitude of Spiegel Grove, with a length of 510 feet and width of 84 feet, makes it one of the most impressive dive sites in the Keys. It’s said that even after a hundred dives, divers may still discover unexplored sections of this artificial reef, which can sometimes disappear into a blue-green haze on less clear days. Divers can also get lost on the wreck, as it’s just so big.
Almost instantly following its sinking, Spiegel Grove became a beacon for marine life, attracting everything from large groupers to a schools of tropical fish. The wreck’s considerable size offers a more extensive habitat than any natural reef structure in the area. Coral growth has progressively enveloped the ship, fostering a vibrant ecosystem with thousands of species of fish and marine life
Clear days enable sights down to the sandy bottom at around 130 feet depth, while mooring buoys provide safe and environmentally acceptable boat tie-offs. Exploring Spiegel Grove delivers not only a one-of-a-kind diving experience, but also insight into nature’s transformational power over man-made structures.
Exploring the Spiegel Grove Wreck
The Spiegel Grove wreck offers an incredible diving experience with its various sections and areas of interest. As one of the largest wrecks to become an artificial reef, it provides an awe-inspiring sight for divers of different experience levels. The wreck sits upright on the sandy bottom, with the bow accessible at around 95 feet and the stern at 80 feet. Most mooring lines are set at about 70 feet, allowing for easy access to different parts of the ship.
The wreck’s superstructure is designed with divers in mind, featuring swim-throughs at regular intervals. These passages offer a glimpse into the ship’s interior, where history and excitement collide. Inside the wreck, divers must exercise caution and proper training to avoid hazards and ensure their safety. The ship’s crane arms, adorned with colorful sponges and corals, make for stunning photography subjects. Divers can encounter an array of marine life while exploring the Spiegel Grove. Tropical reef fish fill the water column, while larger pelagic species roam the area. Barracudas, jacks, spadefish, sharks, Goliath grouper, queen angelfish, and nurse sharks are among the common inhabitants.
The wreck’s size makes it simply impossible to explorer the whole dive site in one dive, in fact – you would need at least 4 dives for a general total impression and even way more dives to really say you know your way around the wreck. Navigating the Spiegel Grove wreck poses some challenges and requires proper precautions. Divers must be advanced level certified due to the depths involved. Proper dive planning, understanding the currents, and using the wreck to their advantage are crucial to having a safe and enjoyable experience. It’s recommended to have a dive guide, who can lead you to the best spots and easy swim-throughs.
Safety Considerations
When diving the Spiegel Grove, safety is of the foremost importance. Divers must have advanced level certification due to the wreck’s depths. Regular diving experience and knowledge of wreck diving techniques are also essential.
Dive operators and guides play an important role in ensuring safety. They conduct thorough briefings covering entry, exit procedures, navigation, air management, and emergency protocols. Divers must pay close attention to these briefings and ask for clarification if needed. Emergency procedures should be well understood and reviewed before each dive. Divers should always have the required safety equipment with them, such as dive computers, lights, and signaling devices.
A safe dive requires effective air management. The rule of thirds is followed, with one-third of the air and time reserved for the return trip and emergencies. To avoid decompression sickness, it is critical to check air consumption and bottom time on a regular basis.
Penetration into the wreck is an intriguing experience, but comes with risks. Exploring closed chambers or tunnels requires proper training. Divers should never enter regions where they cannot see daylight at the exit or where they cannot be within close proximity of their diving buddy.
Hazards within the wreck, such as entanglement risks, demand cautious movement and a good buoyancy. Divers must be aware of surroundings to avoid accidents. Interactions with marine life should be conducted with respect and safety in mind. Divers must refrain from touching marine life and wreck structures and avoid collecting souvenirs.
