A Deep Dive Into the Lefkada Undiscovered Islands Boat Trip

Starting Point and Duration

The tour kicks off early at Nydri harbor, around 9:30 am, with a roughly eight-hour outing. This timing gives you plenty of daylight to enjoy the stops and the boat journey without feeling rushed. The group size is capped at 100 travelers, so it’s not too crowded, but large enough to be lively. The boat itself provides shade and umbrellas, ensuring you stay comfortable as you cruise along.

The Journey and Itinerary Breakdown

First Stop: Papanikolis Cave

Our adventure begins with a photo stop at the Papanikolis Cave on Meganisi. This spot is known for its dramatic rock formations and a bit of history—it’s a cave that once served as a hiding place during wartime. The visit lasts about 15 minutes, giving enough time for photos and a quick look. It’s a great way to set the tone for a day filled with striking scenery.

Review highlight: One traveler, Steve_S, called the day “extremely enjoyable,” noting the “breathtaking scenery” and the “crystal-clear sea,” which really helps set expectations for the kind of views you’ll encounter.

Second Stop: Fermékoula Island and Lighthouse

Next, you’ll stop at Fermékoula Lighthouse, a tiny island called Formekoula, for about 35 minutes of swimming and snorkeling. This is the highlight for many—crystal waters and a peaceful setting. Since it’s a home for Mediterranean seals, it’s quite a unique spot, and the shallow waters make it accessible for everyone.

Practical tip: Bring beach shoes, as the pebbles can hurt, as a reviewer pointed out, but the snorkeling here is worth it, with many describing the waters as “crystal clear.”

Third Stop: Kastos Island

The boat then anchors at Kastos, a quiet island known for its delightful harbor, simple life, and peaceful beaches. You get about an hour and a half for lunch, which can be a highlight if you like authentic Greek tavernas and fresh seafood. During this time, you’re free to explore, eat, or relax at your own pace.

Onshore dining isn’t included, but the town’s charm makes it a fun place to wander. If you’re hungry for good value and a laid-back vibe, you’ll enjoy this stop.

Fourth Stop: Lake Kastos Beach

Post-lunch, the boat heads to Lake Kastos Beach for about an hour of swimming. This is a lovely, quiet spot for relaxing and snorkeling again. The shallow waters and peaceful surroundings mean you can unwind and enjoy the last bit of sun.

Review insight: The calm waters and scenic views are what most travelers seem to love about this part of the trip.

Fifth Stop: Asprogiali Beach

Continuing the island hopping, the next stop is Asprogiali Beach for another hour of swimming and relaxing. It’s praised for its spectacular beaches, offering another opportunity for sunbathing and cooling off. If you’re a beach lover, this will feel like a real treat.

The Return Journey

On the way back, the boat passes by Scorpios and Madouri islands, both famed for their beauty and historical significance. You can snap some photos from the boat—no stops here, but it’s a chance to appreciate these iconic spots from afar.

The trip wraps up back in Nidri around 5 pm, giving you a full day of adventure, relaxation, and exploration.

What’s Included and What’s Not

The tour price includes snorkeling equipment and umbrellas, which is handy for spending hours in the sun and enjoying the water. The snorkeling gear is shareable, so don’t expect individual sets, but enough to give everyone a chance to explore underwater.

Food and drinks are not included, so plan ahead. Many travelers bring snacks or plan to eat during the free time in Kastos. The boat doesn’t serve meals, but the opportunity to dine in the harbor town is a plus for those who want fresh local cuisine.

The Experience and What You’ll Love

The reviews highlight the stunning scenery—the transparent waters, dramatic caves, and peaceful islands. One traveler called the day “good value for money,” emphasizing the variety of stops and the friendliness of the crew.

People also appreciate the relaxed pace, with plenty of swimming opportunities and free time to explore. The crystal-clear waters seem to be a recurring highlight, so if swimming and snorkeling are your things, you’ll be happy here.

Considerations Before Booking

If you’re someone who needs a full meal included, this trip might not be ideal, as lunch is on your own. Also, if you’re prone to seasickness, keep in mind that boat trips can be affected by weather—though the tour provider offers a full refund or rescheduling if canceled for bad weather.

Beach shoes are recommended for comfort on pebbly beaches, and bringing sun protection is a smart move, especially since the boat has umbrellas but limited shade.

Who Is This Tour Best Suited For?

Travelers looking for a relaxed, scenic day with opportunities to swim, snorkel, and explore small Greek islands will find this trip appealing. It’s suitable for anyone comfortable on a boat and eager to see some lesser-known, peaceful spots away from the crowds.

If you enjoy a good mix of sightseeing, water activities, and local island charm, this trip offers a well-rounded day out. However, if you’re craving a full meal or prefer a guided tour with included dining, you might want to explore other options.
