An In-Depth Look at the Experience

The journey begins with convenient hotel pickup, a detail travelers appreciate as it spares the hassle of logistics.

Once aboard the glass-bottom boat, you’ll immediately notice the relaxed, friendly atmosphere, led by a guide or captain who’s knowledgeable about the sights and marine life, according to reviews.

The Boat Ride & Scenic Coastline

The vessel itself is designed to give passengers excellent views—especially with its glass bottom, which is ideal for those wanting to observe marine life without getting wet. The boat glides smoothly along the coast, revealing stunning coastal landscapes that look like they belong in a travel magazine. If you’re a photographer, you’ll love the chance to capture pictures of rugged cliffs, hidden coves, and lively seabirds.

Turtle Island (Marathonisi)

The first major stop is Marathonisi, better known as Turtle Island. Its unique turtle-shaped silhouette and white sandy beaches make it instantly recognizable. This island is a protected nesting site for Caretta Caretta turtles, which adds a layer of excitement for wildlife enthusiasts. As one reviewer noted, seeing turtles in their natural habitat was a highlight — “Luckily, I also saw a turtle!” — and it’s common to spot them bobbing in the waters around the island.

It’s worth noting that some travelers feel the crowds can diminish the feeling of exclusivity at Turtle Island, especially during peak season. One reviewer mentioned how the turtle beach can get completely overrun with travelers and that they were left sitting for an hour. If avoiding crowds is your priority, early mornings or weekdays might be better, but that’s something to keep in mind.

Exploring the Caves & Snorkeling

Next, the boat navigates around the Keri Caves, a series of dramatic sea caves carved by the waves over centuries. These caves are a major draw for photographers and adventure lovers alike. Many reviewers loved the snorkeling opportunities here, describing it as “beautiful blue water” perfect for exploring marine life. You can stay dry in the glass-bottom boat or choose to jump in if you’re feeling confident — just be sure to bring your waterproof camera.

The caves themselves are a highlight, with some reviewers appreciating the well-organized stops and the knowledgeable guide sharing insights into the geology and history of the area. One reviewer specifically mentioned how the boat stopped near the caves, giving plenty of time for snorkeling and exploring.

Turtle Island & Free Time

The final stop is Turtle Island, where you’ll have about 45 minutes to relax, take photos, or snorkel. Many travelers appreciated the ample time to swim and look for turtles. One reviewer mentioned that “the tour lasted about 3 hours, with enough time to see the turtles and snorkel,” highlighting the value of the time allocated.

Practical Details & Tips

The tour lasts roughly five hours, making it an efficient option for those with limited time. It’s priced at $59 per person, which is considered reasonable given the inclusion of pickup, guide, bottled water, and boat ride. It’s a good deal for those wanting a comprehensive experience without paying for a full-day excursion.

To maximize your enjoyment, bring sunscreen, a hat, sunglasses, and a towel. Having a waterproof camera or phone is also recommended for capturing the scenery and wildlife. As some reviews suggest, the quality of the experience can depend heavily on weather conditions and crowd levels, so flexible planning and early booking are wise.
