Melissani Cave is a lake inside the earth near Sami, where a boatman rows you across water so clear that the boats seem to float, lit by sunlight through a collapsed roof. This guide explains when the light is best, how the boat tour works, the official ticket prices and opening hours, the discount with Drogarati Cave and how to avoid the queues.
Melissani is a lake cave at Karavomylos, on the coast road between Sami and Agia Efimia. Part of its roof fell in long ago, leaving a wide opening to the sky above a lake of brackish water, about 20 m below ground level. The cave has two parts: the sunlit chamber under the open roof and a darker chamber hung with stalactites, with a small islet between them.
The water is a mixture of rain-fed groundwater and seawater. In 1963 Austrian geologists showed with dye tests that seawater disappearing into the Katavothres sinkholes near Argostoli, on the other side of the island, travels underground and emerges along this coast, passing through Melissani on the way to the sea at Karavomylos. The cave was explored in 1951 by the speleologist Giannis Petrochilos.
In antiquity the cave was a place of worship of Pan and the nymphs. Excavations led by the archaeologist Spyridon Marinatos found a sanctuary of Pan on the islet in the lake, and the finds are held by the Archaeological Museum of Argostoli, which has been closed since the 2014 earthquakes.
The local legend gives the lake its name: the nymph Melissani is said to have drowned herself here because Pan did not return her love. Another version tells of a shepherdess who fell into the lake while chasing a lost sheep. The boatmen often tell one of the stories on the way round.
The effect everyone comes for depends on the sun. When it is high enough to shine straight down through the opening, the light strikes the water and the bottom of the lake, turning it a glowing turquoise-blue and making the boats look as if they hang in mid-air. That happens around the middle of the day, roughly from late morning to early afternoon on a sunny day, and best of all in summer when the sun is highest.
Early in the morning, late in the day, on cloudy days and in spring or autumn the lake is still beautiful but darker, a deep blue-green rather than luminous turquoise. The catch is that midday is also when the coach tours arrive, so in July and August expect a queue at the best time. If the light matters most to you, accept the wait; if not, come at opening time.
From the ticket office a sloping tunnel with steps leads down to a small landing on the lake. There you board a wooden rowing boat with a few other visitors, and a boatman rows a short loop around the lake, past the islet and through the light and shadow of the two chambers. The trip is short, usually a matter of minutes rather than an hour, and the time on the water is the whole visit.
Swimming is not allowed. Phones and cameras are fine, but the light is tricky: turn off the flash and shoot towards the lit water rather than the opening. The tunnel and landing can be damp, so wear shoes with grip, and note that the descent involves steps, which may be difficult for wheelchair users.
The caves are run by the Municipality of Sami, which publishes the prices. In 2026 an adult ticket costs €10; a reduced ticket of €5 applies to children aged 6 to 18, students, over-65s and large families; and children under 6, people with disabilities and permanent residents of the municipality go free. If you show your Melissani ticket at Drogarati Cave, the adult entry there drops from €6 to €4. A €40 priority ticket is also listed. Tickets are sold on site.
Opening hours change through the season and are announced by the municipality at short notice. In 2026 the caves opened for a few days around Easter in April, ran from 10:00 to 16:00 in the first weeks of May, opened daily from 09:00 to 18:00 from 3 July, and from 13 October moved to 10:00 to 15:00, with last entry at 14:30. Outside the main season they may be closed or open on reduced days, so check the latest announcement on the Municipality of Sami's website before you drive over.
Melissani is about 3 km from Sami, 28 km from Argostoli (roughly 35 minutes) and about 7 km from Agia Efimia. There is a car park by the entrance, which gets busy around midday in summer. KTEL buses between Argostoli and Sami pass nearby, but timetables are thin.
Most people combine Melissani with Drogarati Cave, about 6 km away by road, and a swim at Antisamos or one of the east-coast beaches. Many island tours include both caves and the Myrtos viewpoint in one day, which saves the parking but fixes your time at the lake.
Around midday on a sunny day, when the sun shines straight through the collapsed roof and lights the water turquoise. In summer that is also the busiest time, so expect a queue.
In 2026 the Municipality of Sami charges €10 for adults and €5 for children aged 6 to 18, students and over-65s; under-6s go free. With a Melissani ticket, adult entry to Drogarati Cave costs €4 instead of €6.
Not as a single ticket in 2026, but showing your Melissani ticket at Drogarati reduces the adult price there from €6 to €4, so both caves cost €14.
No fixed all-year timetable is published. Hours change through the season, from 09:00–18:00 in high summer 2026 to 10:00–15:00 from mid-October, and the municipality announces each change.
No. Swimming is not allowed; the lake is visited only on the short boat tour with a boatman.
