Twin Wrecks, Tenerife: shallow wreck diving near Puerto Colón

The Twin Wrecks consist of two small boats positioned only a few metres apart on a relatively flat, sandy seabed. Unlike larger shipwrecks that rise high into the water column, these hulls sit low to the bottom, creating a specific type of landscape where the vessels are the primary points of interest. The topography around the wrecks provides very little natural relief, meaning the hulls themselves serve as the main structural habitat for local marine life. One of the two wrecks has experienced more significant collapse over time, while the other remains in relatively better condition for exploration.

Approaching the site by boat from the Puerto Colón or Costa Adeje area, you will find a location that is notably sheltered. The descent is straightforward, as the wrecks lie at a consistent depth between 18 and 22 metres. Because the seabed is primarily sand, your buoyancy control is essential to avoid silting up the area around the hulls, especially when navigating close to the structures. The layout allows for easy navigation between the two vessels, offering a repetitive but engaging dive profile that focuses on the details of the wreckage.

The site functions as a concentrated hub for macro life, as the presence of the hulls provides shelter and surfaces for various invertebrates. You will often find crabs and lobsters tucked into the crevices of the more collapsed wreck, taking advantage of the small overhangs. Shrimps are also common throughout the site, often found hovering near the structures or moving across the sandy patches between the boats. For those with an eye for smaller details, the proximity of the wrecks makes it a productive spot for close-up photography.

Beyond the small creatures living within the hulls, larger residents are frequently encountered in the surrounding water. Stingrays are known to patrol the sandy bottom, often partially buried or gliding quietly near the edges of the wrecks. You may also see barracuda and amberjack cruising the perimeter of the site, taking advantage of the structure to hunt. These larger fish add a sense of movement to the dive, patrolling the open water just above the sandy floor.

The environment at Twin Wrecks is characterized by its calm and predictable nature. The site is situated in a way that provides protection from heavy swell, which contributes to the consistently high visibility reported by divers. This makes it an excellent location for those looking to practice precise buoyancy or for photographers who need a stable platform to capture the fine details of the marine life. The lack of significant current ensures that you can spend your bottom time exploring the hulls without fighting against the movement of the water.

While the site is easy to dive, the density of life around the hulls requires a methodical approach. Moving too quickly or creating large bubbles near the wrecks can easily spook the more sensitive residents like seahorses. Taking the time to hover steadily allows you to observe how the fauna interacts with the man-made environment. The combination of the twin hulls and the sandy expanse creates a unique micro-habitat that differs significantly from the deeper, more vertical profiles found elsewhere in Tenerife.
