Your adventure begins with hotel pickup from one of five convenient locations around Heraklion—Xeropotamos, Karteros, Heraklion city center, Kokkini Hani, or Hersonissos. The air-conditioned transfer ensures comfort as you leave behind the bustling town for a scenic journey down to South Crete.
Traveling through varied landscapes, you’ll pass mountains, traditional villages, and patches of lush greenery. This drive alone adds a layer of enjoyment, giving you a taste of Crete’s diverse scenery before the underwater excitement. Our source indicates that the guides are well-versed in the local terrain, making the trip both informative and visually appealing.
Once at the southern coast, your guide will brief you on the Byron I wreck, which sank in 1985 after encountering bad weather. The ship was carrying 11,000 tons of sugar, and though it’s now resting on the sea floor, it’s become a bustling habitat for marine creatures.
The wreck is about 100 meters long and lies on the seabed, providing ample space for exploration. You’ll swim through this relic, observing the marine life that now calls it home—groupers, octopuses, moray eels, and lionfish, among others.
According to a review, “The instructors Chris and Leah were amazing and really friendly and helpful,” which emphasizes the supportive environment you’ll find. The clear waters and excellent visibility make this an ideal spot for photography and underwater observation.
You’ll enjoy two guided dives during the tour. Each dive is led by an instructor who will ensure safety and answer any questions along the way. The full set of scuba gear is provided, along with safety equipment and oxygen. You can expect to spend roughly 45 minutes to an hour underwater, depending on conditions and your comfort level.
Between your dives, you’ll have the chance to snack on local fruits and drinks, helping you maintain energy for the next round. The guides are known for their attentiveness, making sure everyone feels comfortable and confident throughout.
After your second dive, there’s a brief debrief with your instructor. They’ll help log your dives, answer questions, and chat about the marine sights. This personal touch is appreciated—reviewers highlight the “undivided attention” from guides, which enhances the overall value.
While the tour doesn’t include underwater photography equipment, you might find opportunities to capture stunning shots in the crystal-clear waters. Some participants also opt to rent GoPro cameras (not included), which could be a worthwhile investment for memorabilia.
The day winds down with a scenic drive back to your hotel, reflecting on the underwater wonders and Crete’s stunning landscape. It’s a full 8-hour experience, balancing activity with comfort, perfect for those who want an immersive diving adventure without rushing.

At $203 per person, this tour offers a solid value, especially considering the private transportation, full scuba gear, and guided instruction. The inclusion of snacks, drinks, safety equipment, and insurance adds to the convenience and peace of mind. For certified divers looking to explore a historic wreck with expert supervision, it’s a fair price that combines adventure with safety.
Being a private group experience means fewer crowds, more personalized guidance, and the chance to ask detailed questions. This setup is ideal if you prefer tailored attention and a smooth, relaxed outing.
