Kelebekler Vadisi (Butterfly Valley)
Named for a day-flying moth, not a butterfly, in a valley whose cliff path has become too dangerous to recommend. Go by boat.
Enough context, no spoilers
Why it matters
Jersey tiger moths cluster here by the thousand each summer, giving the valley its name. The clifftop path from Faralya is a steep, unmaintained scramble that has repeatedly injured hikers and was closed again by rockfall in May 2025; boats from Ölüdeniz are now the standard and reliable access.
What to know before you go
Start with what it's actually named for, because the honest answer improves the visit rather than deflating it. The "butterflies" filling this valley through summer are, for the most part, a single day-flying moth, the Jersey tiger — black-and-cream striped wings that flash scarlet underneath in flight, dense enough in July and August that the valley earned its name from sheer numbers rather than metaphor. That's one thing worth knowing before you go. The second is more practical, and it's the reason this entry is written the way it is: for the last several years, the only reliable way in has been by sea. A footpath does drop into the valley from Faralya, on the clifftop road above, and it still appears on hiking maps and in older guidebooks as a route down. In practice it is a steep, loose, rope-assisted scramble down an unstable limestone face, it has hurt a meaningful number of hikers who underestimated it, and a rockfall closed sections of it again as recently as May 2025. Treat it as closed unless you are an experienced scrambler travelling with someone who has done it before and has confirmed current conditions on the ground — that is a description of what the path is, not just a caution to be careful. Everyone else arrives by boat, and that is not a compromise: the valley is arguably at its best seen from the water anyway, cliffs closing in on both sides as the boat noses toward a beach with nowhere else to land. Shuttle boats run from Ölüdeniz's Belcekız Beach on a fixed timetable, typically two sailings out and two back across the day, with roughly an hour ashore on each — enough for the beach and a swim, tight if you also want the walk inland to the small waterfall, so decide which matters more before you land. There are no permanent buildings beyond a few seasonal drink stalls; bring cash, water and shade, because there is very little of the last one. The valley empties fast once the final boat leaves, so check the return time twice and do not assume a later, unscheduled crossing will be waiting for you.
