Tour Details

Discover the essence of the Sithonia Riviera with a full-day cruise that blends adventure, natural beauty, and hidden history. This 7-hour boat trip in Halkidiki is the perfect way to experience the jewel of northern Greece — the stunning Toroneos Gulf.

We set sail from the picturesque marina of New Marmaras, a lively seaside town known for its charm and views of Mount Itamos. Our first destination is the iconic Kelyfos Island—a turtle-shaped islet steeped in legend. Its crystal-clear waters and rocky seabed make it an ideal spot for snorkeling and paddleboarding.

As we cruise along the untamed Sithonia coastline, you’ll witness dramatic cliffs, lush pine forests, and secret beaches you can only reach by boat. Next, we navigate through the magical Spalathronisia—a cluster of uninhabited islands with untouched beauty, perfect for swimming in secluded coves.

The journey reaches its climax at the awe-inspiring Porto Koufo—Greece’s deepest natural harbor. Surrounded by steep rock faces, this quiet bay once served as a secret base for submarines during WWII. Today, it’s a peaceful haven where you can swim, relax, and explore the small fishing village, all while soaking in stories from a rich maritime past.

Whether you’re an explorer, a nature lover, or simply seeking serenity on the sea, this cruise in Sithonia is the ultimate way to experience the hidden treasures of Halkidiki.
