Guardians of the Blue: Theodorou & Lazareta offers a compelling chance to experience Crete’s lesser-known isles and underwater secrets in a relaxed, well-organized setting. This half-day adventure, run by Heliophilia, takes you from the harbors near Chania or Kolymbari through scenic waters to two intriguing islands: Theodorou, famed for its wild Kri Kri goats and WWII wreck, and Lazareta, a tranquil spot with a historical Venetian quarantine station.
What draws me most to this experience are the expert storytelling guides—they bring the islands to life, sharing stories that add depth beyond just sightseeing. Plus, the snorkeling around hidden caves and the chance to see a sunken WWII airplane turn this into an active, memorable trip.
One potential consideration is the duration—just four hours—which means a packed itinerary. Some reviewers have mentioned the lack of extensive food options during such a long half-day, so if you’re a foodie, plan to bring a snack or plan accordingly. Still, the focus on authentic natural beauty and quiet discovery makes this cruise stand out.

Starting Point and Logistics
The tour departs from Kolymbari or Chania’s ports, two convenient locations for most travelers exploring western Crete. The trip lasts about four hours, which is just enough time to soak in the sights without feeling rushed. The boat is a private vessel, ensuring a comfortable, intimate journey, with shaded areas and a sun deck to relax on.
Transport is included from Platanias if you choose the pickup option—an effortless way to start your day without worrying about logistics. Check the availability for specific start times, as this may vary, but typically you can plan for a mid-morning or early afternoon departure.
The First Stop: Theodorou Island – Crete’s Wild Heart
Your first anchor is Theodorou Island, dubbed the “Island of Guardians” for good reason. It’s a protected sanctuary with an air of quiet dignity. Here, the Kri Kri goats, a rare and iconic species native to Crete, roam freely, providing a delightful sight for animal lovers. Don’t be surprised if your guide, especially someone like “Nikos” or “Maria” if you’re lucky, shares stories of how these goats are almost impossible to find elsewhere, making this a special spot.
Beneath the surface lies the sunken wreck of a WWII German airplane—a haunting reminder of history lying silent on the seabed. Snorkeling here feels like swimming through a living museum, with fish darting through the wreckage and the sea revealing its stories in silence. It’s one of those sights that sticks with you—an underwater relic that’s both intriguing and poignant.
A reviewer named Noah emphasizes the value of the guided commentary, mentioning that “the guide, boat, and locations were very nice,” though he notes a minor disappointment about the lack of food during the half-day, which is worth planning around.
The Second Stop: Lazareta – A Slice of Serenity
After exploring Theodorou, the boat heads to Lazareta, a tiny, uninhabited island steeped in history. It served as a Venetian quarantine station, which gives it a surreal, almost ghostly atmosphere today. Its turquoise waters and soft shores make it perfect for swimming, relaxing, and soaking in the quiet.
Lazareta offers a different kind of beauty—one that’s sparse yet striking, with a peaceful vibe that makes you want to linger. This stop is especially appealing for those who enjoy swimming in calm waters and wandering in a place rarely visited by travelers. It’s one of those hidden gems known mostly to local guides or keen explorers, adding a layer of exclusivity.
The Return Journey: Glistening Waters and Reflection
As the cruise wraps up, the boat heads back toward port, passing through more scenic waters. The salt on your skin, the stories in your mind, and the serene views make for a restful end to the trip. The cruise covers approximately 18-20 nautical miles, giving you plenty of scenic vistas without long travel times.
What’s Included and What’s Not
This trip offers fresh seasonal fruit, local snacks, and a selection of Cretan wine, which, in my opinion, adds notable value—especially since many similar tours don’t include food or drinks. You also receive snorkeling gear, a stand-up paddleboard, and access to shaded and open deck areas, making it easy to switch between relaxing and active moments.
The experienced local skipper and storytelling guide are core to the experience. Their knowledge turns what could be a simple boat ride into a storybook journey through Crete’s marine and island history.
Who Will Love This Tour?
This experience is fantastic for nature lovers, history buffs, and those seeking tranquility. It’s particularly suitable for travelers comfortable with a half-day commitment, who prefer a private, relaxed setting over large group tours. If you’re traveling with family, a partner, or friends, the private aspect enhances the intimacy.
People who want active snorkeling, exploring underwater wrecks, and enjoying peaceful island stops will find this cruise fulfilling. However, if you’re craving a full day with extensive food options or a more lively party atmosphere, you might find this limited in scope.
Price and Value
At its core, the tour offers a well-balanced mix of scenic beauty, cultural insight, and outdoor activity for a reasonable price. The inclusion of snacks, drinks, snorkeling gear, and a private guide makes it a good value, especially considering the exclusivity and personalized nature of the trip. Just keep in mind that it’s a half-day experience, so for a full-day adventure with meals and multiple stops, you’d need to look elsewhere.
Final Thoughts
Overall, “Guardians of the Blue” is a delightful way to connect with Crete’s quieter side. The combination of nature, history, and relaxation makes it ideal for travelers who want to see something special without the crowds. The knowledgeable guides, especially, elevate the experience, making it both educational and engaging.
If you’re after an authentic, peaceful excursion that reveals Crete’s secret islands and marine life, this cruise is worth considering. It’s especially suited for those who appreciate a relaxed pace, intimate setting, and stories that bring the islands alive.
