Monemvasia's Cliff-Top View Would Make Even Butterflies Nervous

Monemvasia is a Gibraltar-sized rock on the Peloponnesian coast of Greece. It's connected to the mainland by a narrow causeway, has a town at its base, and the scant remains of a town and mighty fortress across the summit. As the wind howled on top (pardon that buffeting), we walked to the very edge of a cliff next to an old Byzantine church. From there it's a sheer drop of what seems like a couple thousand feet -- and no railing. You know that feeling you get when peering tentatively over a cliff -- worried that a freak gust will end your trip? (Or do you? Share your most memorable cliff-top stir-the-butterflies-in-your-belly perch.)
