Discover Portugal’s WWII history with a double dive off Porto, including the renowned U-Boat 1277, marine life, and stunning underwater landscapes.
Exploring historic wrecks is a top-tier experience for wreck diving enthusiasts, and Portugal’s U-Boat 1277 certainly earns its reputation as one of the most iconic in the region. This tour offers certified advanced divers a unique chance to explore a well-preserved WWII German submarine resting at about 30 meters deep, surrounded by Portugal’s vibrant marine life. Alongside the adventure, you’ll also enjoy exploring local reefs or other nearby wrecks, making it a well-rounded underwater journey.
One thing we love about this experience is its blend of history and underwater ecology. The story behind the U-1277, scuttled by its crew to avoid capture at the end of WWII, adds a profound layer to the dive. Plus, the chance to swim around an authentic war relic that’s become an artificial reef is quite special. However, a consideration to keep in mind is that the tour’s depth and technical nature mean it’s only suitable for certified Advanced Open Water Divers (AOWD). Novice divers or non-certified swimmers will need to look elsewhere.
This experience is perfect for divers with a passion for history, wreck enthusiasts, and those seeking a visually striking underwater landscape. If you’re comfortable at depth, enjoy discovering underwater stories, and want to see Portugal’s marine biodiversity, this tour will likely be a highlight of your trip.

From here, you’ll meet your guide and fellow divers, setting the tone for a small, intimate group—limited to 8 participants—which means more personalized attention and less chaos.
Before getting into the water, your guide conducts a thorough safety briefing lasting around 30 minutes. Expect detailed instructions tailored to the specific conditions of the day, including dive profiles, hand signals, and emergency procedures. We found this step invaluable, especially given the depth and complexity of the U-Boat 1277.

The underwater landscape around the wreck is lively, with marine life thriving on the artificial reef, including schools of fish, crustaceans, and coral formations.
Your second dive will be at a nearby reef or a different wreck, selected based on current conditions. Expect a different underwater environment, perhaps a vibrant reef teeming with biodiversity or another intriguing wreck. This variety keeps the experience fresh and engaging, making the most of your half-day adventure.
