The Itinerary in Detail

Marianna Shipwreck: A Fascinating Underwater Reef

Our journey begins with a visit to the Marianna shipwreck, located between Naxos and Paros. This spot is a favorite among snorkelers because the wreck has transformed into a vibrant artificial reef. We loved the way the ship’s structure, now encrusted with marine life, creates a bustling habitat for octopuses, small fish, and other underwater creatures. One reviewer mentioned, “It’s like swimming inside an underwater museum, full of life and stories.” The calm waters here provide excellent visibility, making it a perfect spot for snorkelers of all levels to observe the marine environment up close.

Parthena Island: A Hidden Gem Only Approached by Boat

Next up is Parthena, a tiny island crowned by a small chapel and surrounded by crystal-clear waters. The boat drops us just offshore, and we get to snorkel in areas teeming with sea turtles and elusive octopuses. What makes Parthena special is its secluded location and untouched charm—you’re unlikely to find travelers cluttering the beaches here. Multiple reviews note how peaceful and picturesque the area is, with one saying, “It feels like you’ve discovered your own private paradise.” The views from the boat are stunning, with rugged cliffs and the chapel’s silhouette adding to the island’s romantic appeal.

Kastraki Rocks: Jumping from the Rugged Cliffs

Our final stop takes us to Kastraki, a rocky outcrop accessible by boat, where you can make a splash from the cliffs. The rocks provide an adventurous twist to the trip—perfect for those who enjoy a bit of adrenaline, or simply want to see the rugged side of Greece’s coastline. Reviewers have appreciated the opportunity to dive from the rocks, calling it “a fun way to end the trip on a high note.” The area also offers excellent snorkeling, with rocky crevices housing various marine species.
