Stepping into the waters off Porto to explore the U-boat 1277 promises an experience that combines history, marine life, and adventure. This tour is designed for certified divers eager to see one of Portugal’s most renowned wrecks, and it’s been highly rated for its authenticity and the chance to see a WWII submarine still teeming with marine activity.
What we love about this experience is the intimate group size—limited to just six divers—which ensures plenty of attention and safety. The fact that hotel pickup and drop-off are included makes logistics straightforward, removing the hassle of finding a meeting point. That said, it’s important to note this is an advanced diver activity, so beginners or uncertified divers will need to look elsewhere or opt for a supervised “try dive” with a certified instructor.
This tour suits adventurous travelers with a love for history, underwater photography, or marine biology. If you’re comfortable with advanced open water certification, this dive offers a unique glimpse into a WWII relic that doubles as a vibrant marine habitat.

The U-boat 1277 is a WWII German submarine, and exploring its remains offers a tangible connection to history. Located in the Atlantic waters just off Porto, the wreck is well-preserved enough to see key features like the welded steel pressure hull, measuring about 22mm thick, and the combat periscope gleaming stainless steel. This is a rare chance to observe the armor and structure of a WWII vessel in its final resting place.
The boat’s tower is still visible, including the hatch and other structural elements that tell stories of the submarine’s service and sinking. As the reviewer noted, “You can still see in the tower the pressure hull, consisting of welded metal plates approximately 22mm thick, the combat periscope with the shining stainless steel, and the hatch without cover,” which makes it a true historical treasure.
Unlike many wrecks that are photosynthetic ruins, the U-1277 is a thriving reef. Its hull is cloaked in small white anemones, with thousands of them creating a stark, almost magical contrast against the dark metal. Expect to see curious octopuses investigating nooks, lobsters scuttling around, and a community of pink anemones adding bursts of color.
Reviewers highlight how the wreck functions as a habitat, attracting a variety of marine animals. One mentioned how the site is “full of life because the submarine lies like a reef,” which emphasizes how this dive combines history with nature. This is an ideal experience for underwater photographers or those simply wanting to witness marine ecosystems thriving on human-made structures.
Meeting at Marina de Leça, just outside Porto, the tour begins with a brief orientation about the wreck’s history and what to expect underwater. When everyone is ready, the group heads out to the dive site. The entire experience lasts roughly three hours, including briefing, the dive, and return.
The small group limit of six ensures plenty of attention from guides, which is especially important for an advanced dive. The tour operator mentions that if you’re an Open Water diver, you’ll be redirected to alternate diving locations, but for Advanced Open Water certified divers, this is a prime opportunity.
Once underwater, you’ll have the chance to explore at your own pace, guided by professionals who are familiar with the wreck. Expect to see the structure’s key features—the tower, hatches, and sections of the hull—while observing the marine life that has made it home.
Reviewers praise the professionalism and friendliness of the staff, noting that they are well-versed in safety and history. One review specifically called out the guides’ approach as “reallly friendly and professional,” making the experience both safe and educational.
Costing about $161.95 per person, the price reflects the exclusivity of the small group and the specialist nature of the tour. Given the includes (hotel pickup, small group, expert guides), it’s a fair value for those seeking a memorable underwater adventure.
Remember, confirmation is immediate, and cancellations are free up to 24 hours beforehand, which is a flexible policy should weather conditions or personal plans change.
