Glass Bottom Boat Tour Laganas: Turtle Spotting & Snorkeling

Three hours watching turtles from below the waterline, then swimming in the shallows where they live

A three-hour glass bottom boat tour from Laganas that combines turtle spotting in shallow water with snorkeling at Marathonisi island and Keri caves. The boat has a glass floor so you watch loggerhead turtles (Caretta Caretta) without diving, then stop to swim in clear turquoise water surrounded by white rock formations and golden sand. A live English-speaking guide leads the tour; hotel pickup and air-conditioned transport are included.

Step-by-step itinerary

Glass bottom boat tour and swimming

• Board the boat and learn about turtles
• Spot turtles near Laganas beach
• Swim and snorkel at Marathonisi beach
• Visit Keri area and enjoy the scenery

The Experience

The boat leaves Laganas and heads into the shallow water where loggerhead turtles feed and rest. You'll hear about the Caretta Caretta turtles from the crew as they navigate the area, and the glass bottom lets you watch them move through the water below without getting wet or needing to dive. The three-hour tour is built around spotting, so the pace stays slow enough to actually see them.

After the turtle zone, the boat stops at Marathonski (turtle island) where you jump in to swim and snorkel in water so clear it shows the golden sand and rocks underneath. The water is shallow enough to stand in, and the scenery—green cliffs rising behind turquoise shallows—frames the whole stop. From there the tour moves to Keri, where white rocks line the sides and light brown sand creates depth in the clear water. Both stops let you stay in as long as you want within the tour window.

The boat is air-conditioned and pickup runs from your hotel, so you don't arrange transport separately. Small groups keep the boat from feeling crowded, and you can choose between a private boat or a semi-private option with up to eleven people. The crew handles navigation and timing so the three hours hold all three stops without rushing.

Is this one for you?Choose the private boat if your group wants the turtle spotting and snorkeling without sharing the boat; the semi-private option works if you're comfortable with up to eleven other people and want to split the cost. Either way, the glass bottom boat means you see turtles without needing to dive or be a strong swimmer.

Top questions

What are the loggerhead turtles like when you see them from the glass bottom?

Loggerhead turtles (Caretta Caretta) live in the shallow water around Laganas and feed on the sandy bottom. The glass bottom boat lets you watch them move through the water at their own pace without disturbing them or needing to dive.

Can you actually snorkel at Marathonski island, or is it just swimming?

You can snorkel at Marathonski island in the shallow turquoise water. The crew stops there specifically for swimming and snorkeling, so you bring your own gear or ask about rentals when you book.

How does the glass bottom boat work—do you sit below the waterline?

The glass bottom boat has a viewing area with a glass floor so you can see into the water while staying dry and seated. You're not submerged; the glass lets you watch turtles and the seafloor from inside the boat.

Does the tour include hotel pickup, or do you meet the boat at the dock?

Hotel pickup from your accommodation in the area is included, along with air-conditioned transport to and from Laganas. You don't need to arrange your own way to the boat.

What's the difference between the private boat and the semi-private option?

The private boat is just your group; the semi-private option holds up to eleven people. Both follow the same route and stops, so you choose based on whether you want to travel alone or are comfortable with a small group.

Is three hours enough time to see turtles and snorkel, or does it feel rushed?

The three-hour tour is designed to fit all three stops—turtle spotting in Laganas shallows, snorkeling at Marathonski, and the Keri caves area—without rushing. The boat crew plans the timing so you get time in the water at each stop.
