Fodor's Expert Review Petaloudes
The "Valley of the Butterflies" lives up to its name, especially in July and August. In summer the callimorpha quadripunctaria, actually a moth species, cluster by the thousands around the low bushes of the pungent storax plant, which grows all over the area. Through the years the numbers have diminished, partly owing to busloads of tourists clapping hands to see them fly up in dense clouds—an antic that causes the moths to deplete their scant energy reserves and is strongly discouraged. Access to the valley involves an easy walk up an idyllic yet crowded trail through a pretty wood past a stream and ponds.
