We are staying 3 nights near Kardamyli. We want to go to Foneas beach and Diros caves while there. Has anyone on this forum been to them and can you recommend anything else to do or see while there?
I have not been to the two places you are suggesting, but I did go to Kardimyli on our recent Rick Steves tour of the Peloponnese. Honestly, there is not a lot to do in the area other than hiking or going to the beach. Rick bills it as a vacation from your vacation.
We loved Greece!
I did not visit those places. I did some hiking, and on a rainy day, we drove up to Mystras, as we had intended to stop there en route from Nafplio and ran out of time. It was a long day trip, but I am glad we did not miss it.
You need a resource on the Mani--the recent Bradt guide is really comprehensive for the Peloponnese.
There are some scenic drives and lots of Byzantine churches to see if you are into that kind of thing. There may be something of interest to you in Kalamata. It just depends on how much driving you wish to do--but like the previous poster, we mostly relaxed, hiked, and went to the beach while in Kardamyli.
