Travel to a far-flung corner of Peloponnese, where the Caves of Diros reveal underground secrets.
Descend into an underground cave that has existed since before the Neolithic era. View the dramatic stalactites and stalagmites formed from millions of years ago, their earthy hues a stark contrast to the crystalline aquamarine seawater.
Get on a boat to sail around this hair-raising cavern, where a lattice of winding waterways fans out into the eerie darkness. This is what the locals call the road to the shadowy Hades. It’s yours for the day.
