The partially collapsed roof of Melissani Cave acts like a natural skylight. To see the brackish water turn its famous shade of turquoise, you need direct sunlight hitting the lake. Timing your visit is the most important part of your trip.
What time of day is best for Melissani Cave?
You should arrive between 11:30 and 14:00.
During this window, the sun is high directly above the cave. The sunlight beams through the collapsed roof and hits the lake surface. This causes the water to glow a brilliant turquoise color.
What causes the blue water in Melissani Cave?
Direct sunlight refracting through the deep, clear brackish water creates the bright blue effect.
The lake is up to 39 meters deep. The water travels 15 kilometers underground from the Katavothres sinkholes. When the midday sun hits this deep, clear water, it creates the glowing color.
What are the best months to visit?
June to September are the optimal months for visiting Melissani Cave.
The cave is open daily from May to October. However, the summer months offer the strongest direct sunlight and the clearest skies. This guarantees the best lighting inside the cenote.
| Month | Status | Sunlight Quality |
|---|---|---|
| May | Open daily | Good |
| June to September | Open daily | Peak |
| October | Open daily | Fair |
| Nov to April | Closed | None |
How long does the cave visit take?
The mandatory wooden rowboat tour lasts approximately 10 to 15 minutes.
You will walk down a sloping pedestrian tunnel to the lake's edge. This takes about five minutes. Then, you board a small boat for your guided tour across the 160-meter long lake.
How do I time my arrival perfectly?
Rent a car and drive yourself to arrive right at peak sunlight.
Driving takes 35 to 40 minutes from Argostoli. Ample free parking is available right outside the cave in Karavomylos. Arriving by car lets you skip the fixed schedules of the large tour buses.
Can I see Drogarati Cave on the same day?
Yes, Drogarati Cave is only 3 kilometers away.
You can buy a combo ticket for both caves for 13 EUR. Drogarati is 60 meters underground and stays at a constant 18 degrees Celsius (64F). Because Drogarati does not rely on sunlight, you can visit it before or after your midday Melissani tour.
