Exploring Korcula’s Underwater Charm: The Semi-Submarine Experience
If you’re looking for a fun, family-friendly activity that combines a bit of adventure with a good dose of sightseeing, the Korcula Semisubmarine Tour might just be what you need. This 45-minute voyage aboard a uniquely designed vessel offers a chance to peek beneath the waves without getting your feet wet—perfect for those who prefer dry land but still want a taste of marine life. The tour departs from Korcula’s East Port and remains above sea level, while its underwater observatory, situated just 1.5 meters below the surface, reveals the vibrant underwater world right in front of your eyes.
One of the things we love about this experience is its accessibility and safety. The semi-submarine’s design means everyone, regardless of age or swimming ability, can enjoy watching marine life through their personal viewing window. Plus, the fact that you can walk on the deck at any time adds an extra layer of comfort and flexibility—you can choose to stay cozy inside or step out to take in the views of Korcula’s historic Old Town, which looks stunning from any angle.
A potential consideration is the short duration—at just 45 minutes, it’s a quick trip. While this is perfect for a light, engaging excursion, those seeking a longer underwater adventure might feel it passes too quickly. Plus, weather can influence the experience, especially if you opt for the night tour with underwater lights, so checking the forecast before booking is wise.
This tour suits travelers of all ages, especially families with children, curious snorkelers, or anyone interested in a relaxed, scenic exploration of Korcula’s marine environment. If you’re after an easy, well-priced activity that offers impressive views and a bit of underwater magic, this semi-submarine tour is a solid choice.
