Discover the unique glass-bottom boat tour off Kos featuring a mermaid and diver, snorkeling, shipwreck views, and a fun 1.5-hour experience suited for all ages.
Exploring Kos by water offers a fantastic way to see the island’s vibrant coastlines, and the Yellow Submarine cruise provides a lively, family-friendly twist on the usual boat trip. This 1.5-hour adventure features a distinctive glass-bottom vessel, a whimsical mermaid and diver performance, and plenty of chances to snorkel, swim, or simply relax on deck. It’s a tour designed to be fun, engaging, and visually captivating—perfect for families, couples, or anyone looking to add a splash of magic to their day in Kos.
What we love most about this experience is the interactive element: watching the mermaid and diver perform, plus the opportunity to snap photos with them. The boat’s glass bottom allows you to gaze beneath the surface without getting wet—an excellent feature for those hesitant about snorkeling or just wanting a unique view of the seabed. One minor consideration is that the trip doesn’t include food or drinks, so you’ll want to bring your own or plan to purchase from the onboard bar.
This tour suits travelers seeking a lighthearted, family-friendly excursion with a mix of entertainment and opportunity for water activities. It’s also a good pick for those wanting a quick, memorable experience that captures the essence of Kos’s coastal beauty without a full-day commitment.
