The Itinerary in Detail: What to Expect

Planning more time in Lefkada? We've covered other experiences worth considering.
Starting Point & First Stop: Papanikolis Cave
The tour kicks off at Port Nidri around 9:30 am. From there, you’ll cruise to the Papanikolis Cave on Meganisi island. This cave isn’t just a pretty sight—it’s steeped in history, believed to have served as a submarine hideout during WWII. The sheer size of the cave is impressive, and it’s a fantastic spot for photos. Expect about 45 minutes of cruising before arriving.
Most travelers will find the cave visit fascinating, especially those interested in wartime stories or natural formations. The experience of seeing a site linked to submarine hideouts adds a bit of intrigue to the day.
Kastos Island: Simple Paradise
Next, you’ll spend around 2 hours on Kastos Island, a tiny but charming place about 8 km long. With fewer than 50 residents, the island offers a peaceful escape with lovely beaches and a slow pace of life. It’s perfect if you’re craving tranquility, and you might find some time to stroll through the narrow streets, browse for souvenirs, or simply soak up the sun.
One reviewer mentioned that Kastos feels like a true hideaway—”blessed with lovely beaches, peace and quiet, and a deliciously simple way of life.” It’s a chance to step back from the busy tourist trail and enjoy unspoiled scenery.
Kalamos: A Mountain Range on Water
The final stop, Kalamos, is not your typical island. Instead, it’s a floating mountain range with tall pine trees growing directly from rocky outcrops. You’ll get about 2 hours here, and it’s a fairly unique experience—standing among pines that reach out over the sea, almost as if they’re insisting on being part of the landscape.
While the views are striking, keep in mind that this isn’t a typical beach destination. It’s more about appreciating the natural beauty and the dramatic landscape. If you’re into nature and scenic vistas, this will satisfy that craving.
What’s Included & What’s Not

The tour covers all fees and taxes, so no hidden costs there. The main expenses not included are transfers from your hotel to Nidri port and back, as well as food and drinks. You might want to bring snacks and water, especially during the hot summer months.
While the actual boat experience can be a highlight, some reviews warn about overcrowding. One guest described it as “the worst boat trip ever,” citing overcrowded spaces and a lack of air conditioning inside the boat, which could make the day less comfortable, especially if you’re sensitive to heat or prefer a more intimate experience.
The boat is fully booked during high season, with a limit set by port authorities, so it’s wise to book at least 18 days in advance if possible. The maximum number of travelers is 150, which means you’ll likely be in a fairly large group.
