The Alistrati Cave is the longest terrestrial cave system in Greece and one of the country’s most impressive subterranean wonders. During our visit, we venture nearly one kilometre deep into the mountain’s interior, walking through chambers adorned with spectacular speleothems — stalactites, stalagmites, and delicate helictites — all formed over millennia by mineral-laden waters.

If conditions are favourable, we may observe bats roosting within the cave system, offering a rare glimpse into the secretive world of these ecologically important mammals.
After emerging from the depths, our exploration continues along the richly biodiverse Aggitis Gorge, carved by the river of the same name. The riverine habitats along the Aggitis River support a wealth of Mediterranean flora and fauna. Among the wildlife we may encounter are: Hermann’s tortoises (Testudo hermanni), sheltopusik (Pseudopus apodus), Black-headed Buntings (Emberiza melanocephala), Sardinian Warblers (Curruca melanocephala) and many other reptile and bird species characteristic of the Balkan Peninsula.

This tour combines subterranean geology with riparian ecology, offering an immersive experience through two strikingly different yet ecologically connected worlds — one hidden beneath the earth, the other thriving along the sunlit banks of a wild river.
