The Alphonse XII. Forget the big, deep wrecks for a moment. This one sits in a mere two metres of water, a splintered wooden hull spread across the shallows. We love it for how accessible it is, even for snorkelers, but it’s the history that really pulls us in. This was a Spanish cruiser, torpedoed by the US Navy in 1898, and you can still see the massive keel, ribs, and scattered hull plates. It’s a real contrast from the dramatic drop-offs elsewhere. Here, the light plays through the water, illuminating the dark wood and the shimmering schools of silvery fish that now dart through the wreckage. You can trace the outline of the deck, picking out details where the ship broke apart. Our favourite part is how the wreck has become an artificial reef, attracting curious French grunts and sergeant majors. It’s not about penetration or tricky navigation; it’s about a gentle exploration of history and the surprising amount of life that has claimed this old warship. It’s perfect for a relaxed second dive or for those days when you just want to soak up some shallow history.

The Alphonse XII was a Spanish transatlantic mail steamer that met its end during a pivotal moment in history: the Spanish-American War. In 1898, while a US naval fleet blockaded the key harbors of Cuba, the Alphonse XII found itself trapped. Rather than allow the valuable vessel to be captured and used by the American forces, the Spanish crew made the difficult decision to scuttle their own ship, sending it to the bottom to deny it to the enemy.

Today, the wreck lies in the crystal-clear waters off Isla de la Juventud in a mere 2 meters of water. This extreme shallow depth makes it less of a scuba dive and more of an incredible snorkeling and free-diving site. You can easily swim down to explore the ship's skeletal remains, which are scattered across the sandy bottom. The boilers and parts of the engine are still recognizable, now completely encrusted in coral and patrolled by curious reef fish. It offers a unique and accessible window into the dramatic events of the late 19th century.
