Day Cruise

On the sun-soaked island of Kos, a unique marine experience awaits visitors eager for a fresh perspective on island life. Sea Explorer’s Day Cruise offers a 90-minute journey aboard the distinctive 17-meter vessel known as the "Yellow Submarine." Departing from Kos’s bustling main port at Akri Kountouriotou Street, this trip blends casual aquatic adventure with engaging opportunities to observe local seascapes and underwater life. The "Yellow Submarine" is not your typical boat tour.

Its design encourages guests to jump into the crystalline Aegean waters for a swim around the vessel, lending a refreshing break under the Mediterranean sun. The cruise features a certified diver who accompanies the group underwater, capturing vivid photos that reveal the island’s underwater realm — from colorful marine fauna to nearby shipwrecks nestled close to the shoreline. These images offer a rare glimpse beneath the waves, making the day memorable for families and friend groups alike.

Kos itself is steeped in history, famed for its ancient ruins and traditions dating back to classical Greece. The coastal waters reflect this heritage, dotted with remnants of maritime past and teeming with vibrant marine ecosystems that support various fish and invertebrates unique to the region. Sea Explorer stands out as a local leader in blending ease of access with memorable active excursions.

Situated in one of Greece’s Cycladic gems, this cruise invites guests to engage directly with the island’s marine environment without the need for advanced skills or rigorous preparation — accessibility meets adventure. From candid swimming and photography to panoramic harbor views framed by distant mountains, the Day Cruise promises both relaxation and connection. For travelers looking to soak in the Aegean’s beauty with a splash of adventure, this voyage delivers an unmatched taste of Kos’s coastal charm.
