The tour begins sharply at 9:30 am at Nidri Port, a location easily accessible via public transportation. The convenient meeting point allows guests to gather with minimal hassle, and the tour ends back at the same spot. Participants receive a mobile ticket and will be notified 24 hours before with detailed instructions and the names, gender, nationality, and date of birth of all participants.
The first stop on this journey is the Papanikolis Cave on Meganisi Island, just 12 nautical miles from Nidri. This sea cave gained fame during World War II as a secret hideout for the submarine Papanikolis. The cave’s immense size is striking, with archaeologists believing it once served as a refuge for submarines after their missions. Reaching the cave takes approximately 45 minutes by boat, making it a captivating highlight early in the day.
The Papanikolis Cave features numerous smaller caverns, offering impressive photo opportunities. Its historical connection as a wartime hideout adds an intriguing layer to the natural beauty, making it a top photo stop and conversation piece during the tour.
Following the cave visit, the boat approaches Kastos Island, a tiny island measuring just 8 km from north to south and less than 1 km wide. With only around 50 permanent residents, Kastos offers a tranquil environment with lovely beaches and a slow-paced lifestyle. This stop lasts for about 2 hours, giving guests the chance to stroll through the village, browse local shops for souvenirs, or relax on the beaches.
Kastos is ideal for travelers seeking a peaceful, unspoilt setting, far from crowded tourist hotspots. The island’s small size and untouched beauty provide a genuine taste of Ionian island life, perfect for those wanting to unwind in nature.
The tour’s final major stop is Kalamos, a distinctive island that resembles a floating mountain range rather than a traditional landmass. Its northern side is covered with tall, thick pine trees of a special species, which cling to rocky precipices and stretch all the way to the water’s edge. This 2-hour visit allows for exploration of the dramatic landscape and marveling at the natural resilience of the pine trees.
Kalamos’ unique geography, with its towering pines and rugged terrain, makes it a compelling stop for nature lovers. The island’s appearance of a mountain range floating on the sea offers dramatic views, perfect for photography and quiet reflection.
One of the tour’s key features is the morning swim at Formekula, a pristine beach where guests can enjoy refreshing water and snorkeling. This stop provides an opportunity to unwind in the calm Ionian waters, with the chance to explore underwater life. The beach’s unspoilt nature makes it ideal for relaxing away from crowded beaches, although there are no food or drinks provided, so bringing water and snacks is advisable.
The overall pace of the trip allows ample time for swimming and soaking up the sun, making it suitable for those looking for a laid-back experience in a scenic setting.

The Papanikolis Cave stands out as the most awe-inspiring natural feature of the tour. Its colossal size and historical roots as a WWII submarine hideaway make it more than just a scenic sight. The cave’s multiple smaller caverns and its proximity to Meganisi’s coast make it a popular photo spot and a conversation starter about Greece’s wartime history.
The boat approach offers close-up views of the cave’s massive opening, and many visitors appreciate the chance to see this extraordinary natural formation up close. It’s a highlight that combines history, geology, and stunning scenery in one impressive stop.

During the 2 hours on Kastos Island, visitors can explore the peaceful village streets, browse local shops, or simply relax on the beaches. The island’s simple way of life and unspoilt landscapes set it apart from busier tourist destinations. The small-scale environment encourages quiet walks and enjoying the views, with opportunities to purchase local crafts and souvenirs.
This stop provides a glimpse into traditional Ionian island living, away from modern developments. It’s an ideal spot for those wanting a tranquil experience and authentic Greek charm.
Kalamos is not a typical island but rather a tall mountain range that appears to float on the water. Its towering pine trees grow wild, even at the most precipitous points, creating a striking natural scene. The trees, believed to be a special species, grow directly from rocky outcrops, emphasizing Kalamos’ rugged character.
The 2-hour visit gives time to appreciate the dramatic landscape, with options for short walks or simply taking in the panoramic views. Nature enthusiasts will find Kalamos’ landscape both inspiring and serene, with its untamed beauty offering excellent photo opportunities.
