Petaloudes
It lives up to its name in all but one important regard: its star attraction isn't actually butterflies. In summer the Callimorpha quadripunctaria, a red- and black-speckled species of day-flying moth known as the Jersey tiger, cluster by the thousands around the low bushes of the pungent storax plant, which grows all over the area. In recent years the number of moths has diminished, partly owing to busloads of tourists clapping their hands to see the creatures fly up in dense clouds—an antic that causes the creatures to deplete their scant energy reserves, thus disturbing them and affecting their reproduction activities (needless to say, it's probably best not to do this). Access to the valley involves an easy walk up an idyllic yet crowded trail through a pretty wood, past a stream and ponds; don't miss the lower half of the trail behind the car park. There are several refreshment points on the route—the best option with the tastiest meals is Butterfly Restaurant Bar, at the end of the downhill trail, which overlooks yet more beautiful green valleys. You must visit at the right time of year to see the moths, typically mid-June to mid-September. Outside of this season, it still makes a pleasant walk, albeit void of moths.
