A doline, also known as a sinkhole or cenote in some regions, is a geological formation characterized by a depression or hollow in the ground surface, typically formed by the dissolution of soluble rocks such as limestone, gypsum, or dolomite.
It is located 1 hr from Napflio or 2.5 hrs from Athens
The place is definitely much more interesting seeing from the sky or by a drone, but anyway is somehow unique.
What is there to see ?
From the parking place you can see one of the holes far in the mountains
The parking is in a small pine tree forest and there you will find a tunnel that leads down to one of the holes.
Down in the hole there is a small church.
It is a short stop to see something different but it is not place that you will add as a must see place in your trip to Greece. If you are exploring the Peloponnese region, than you will most likely find your self near this place, so why not ?
