A Corfu glass bottom boat shows the island’s seabed through glass, from the caves of Paleokastritsa to the islet of Vidos. It features among the Greek tours listed on Greece VIP.
This post covers how the boats work, where they leave from, what passengers see, the sea life, the caves, tickets, children and reviews. Weather, the best time and common questions come last.
What is a Corfu glass bottom boat?
A Corfu glass bottom boat lets passengers watch the seabed through glass without getting wet. On Corfu the term covers an underwater cabin cruise, glass viewing platforms and boats with glass windows.
The best-known version sails from Paleokastritsa on the west coast. Its operators say it is not an ordinary glass-bottom boat.
The booking page for that cruise still carries “glass-bottom boat cruise” in its web address. Its title says underwater cruise.
A Blue Lagoon operator says its glass windows turn the crossing into snorkelling without getting wet.
Glass-bottom boats now run in seaside resorts and lake towns. A petrol-powered version first appeared in 1924.
- Main trip: Paleokastritsa.
- Styles: Cabin, platform, windows.
- Swim: Not needed.
A Corfu glass bottom boat gives a front-row seat to marine life, its operator says.
How does a Corfu glass bottom boat work?
A Corfu glass bottom boat at Paleokastritsa runs in two parts. Guests start on the open top deck, then go down into the underwater cabin.
The top deck shows cliffs, bays and clear water from above. The cabin shows the fish and the seabed.
The boat does not stop during the cruise, so the view moves past the windows. It passes close to the caves for photos but does not enter them.
Reaching the cabin means walking down steps and back up. The boat carries up to 49 passengers.
There is no toilet on board, so the crew suggests limiting food and drink beforehand. Passengers can use the aquarium toilets with their boarding card.
- Deck: Cliffs and bays.
- Cabin: Fish and seabed.
- Capacity: 49.
A Corfu glass bottom boat with a moving view suits short attention spans.
Where does a Corfu glass bottom boat leave from?
A Corfu glass bottom boat leaves Paleokastritsa from a platform behind the aquarium. Corfu Town and Lefkimmi run their own glass-bottom trips.
Online tickets are swapped for a boarding pass at the aquarium ticket office. The A9 bus ends at the large car park nearby.
The operator also sells a combined ticket for the aquarium and the cruise on the same day.
From Corfu Town, a glass-bottom trip crosses Garitsa Bay and circles the islet of Vidos. It leaves free time in the old town.
From Lefkimmi, the southern port, a fast glass-bottom boat crosses to the Sivota islands on the mainland.
- West: Paleokastritsa.
- Town: Vidos trip.
- South: Lefkimmi.

What can passengers see from a Corfu glass bottom boat?
Passengers on a Corfu glass bottom boat see shoals of fish, rocks, seagrass and the sea floor. One reviewer also spotted a barracuda and octopus.
A UK reviewer said the captain placed the boat right above the fish, in crystal-clear water.
A Polish reviewer listed the sea floor, fish, marine plants and rocks. A Spanish reviewer liked seeing deep underwater without getting wet.
Not everyone agrees. Reviewers on a second site found the fish viewing disappointing for the money.
The Vidos trip promises shoals of fish and swaying seagrass from its glass platform.
Visibility depends on calm weather, and one reviewer said bad tides kept a boat from a stop.
- Seen: Fish, rocks, seagrass.
- Bonus: Barracuda, octopus.
- Needs: Calm water.
A Corfu glass bottom boat shows its best views on still, sunny days.
Which sea life lives below a Corfu glass bottom boat?
A Corfu glass bottom boat passes over seagrass meadows, rocky reefs and schooling fish. Posidonia meadows give food and shelter on the scale of coral reefs.
Researchers have studied the Posidonia meadows off the Erimitis peninsula since 2021. They call the area a healthy, rich marine ecosystem that stores blue carbon.
The bogue, a schooling seabream named after its ox-like eyes, rises toward the surface at night.
The peacock wrasse lives around rocks ringed by seagrass, down to 50 metres.
An octopus can spend up to 40 percent of the day in its den. Sightings come down to luck.
Monk seals appear around Corfu from time to time but no longer breed there.
- Plants: Posidonia.
- Fish: Bogue, wrasse.
- Rare: Monk seals.

Which coves and caves line a Corfu glass bottom boat route?
A Corfu glass bottom boat at Paleokastritsa runs past limestone caves and small coves. Corfu is built of limestone, the rock in which caves form.
Boats there name the Blue Eye cave, St. Nicholas cave, the Cave of Love, Marmara cave and Liniodoros cave.
Speedboat trips from the same bay add Limni, Paradise and Stelari beaches.
The Vidos trip describes a wooded island where birds and rabbits roam free, untouched by development. The return leg gives a view of Corfu Town.
The Blue Lagoon lies by the Sivota islands, reached by glass-bottom boat from Lefkimmi. It is said to have sheltered Arabian pirates.
- Caves: Five named.
- Island: Vidos.
- Lagoon: Sivota islands.

What does a Corfu glass bottom boat ticket include?
A Corfu glass bottom boat ticket at Paleokastritsa includes the air-conditioned vessel and a skip-the-line entry. The host speaks Greek and English.
A reservation is valid only for the chosen time slot, and changes are requested ahead. Reduced fares need a valid ID.
Bad weather moves the booking to the next suitable day or earns a refund.
Booking online is recommended rather than required, and it skips the ticket-office queue.
Pets and smoking are not allowed. Guests bring a hat and sunscreen, since one reviewer wanted shade at the harbour.
The operator closes for the winter and reopens the next season.

A Polish reviewer found the floor seating on deck comfortable for small children.
A Hungarian family said the children enjoyed it, and travellers prone to motion sickness were fine.
A French reviewer warned that the cabin shakes and can make guests sick. The operator advises a seasickness pill beforehand. The crew can help if a guest has none.
The boarding points are hard to reach for guests with reduced mobility. One listing calls the cruise stroller friendly but not wheelchair accessible.
- Kids: Family favourite.
- Seasick: Take a pill.
