Zante Sun Travel · Laganas, Laganas Bay
Zante Sun Travel's boat is a hybrid: quick between stops, with a glass floor for the slow part, and it starts with the turtles before anything else. Pick it for the price and the order of the day, as long as you're staying in Laganas or Kalamaki, the only places it picks up.
At $28, this is the lowest from-price for a turtle trip on the bay in 2026. You get a new glass-bottom speedboat that's quick between stops and slows down for the turtles. The day runs the opposite way to most: turtle spotting comes first, then a swim at Marathonisi's Golden Beach, about 20 minutes at the Keri Caves and 20 more at the Myzithres rocks.
Turtles first means you're not watching the clock to get to a beach. A guest wrote that "ending the tour with plenty of time to watch the turtles" was the best part, so the order may vary by departure. Either way, turtle watching has rules: the 2018 code allows two boats per turtle and 10 minutes each, from at least 15 m.
The listing is thin in places. The itinerary barely goes beyond pickup and drop-off, the guide's languages aren't listed, and it includes food and drinks while also telling you to bring your own. Bring water and a snack anyway. At Keri the boat goes into the larger caves when the weather allows. And pickup is Laganas and Kalamaki only: from anywhere else, the Best of Zante glass-bottom boat has a wider pickup area.
Collected in Laganas or Kalamaki and taken to the boat.
