The Valley of the Butterflies (Petaloúdes) is located in the northwestern part of the island of Rhodes, approximately 25 km from Rhodes Town and 5 km from the resort of Faliraki. It is not an amusement park, but a protected natural area. The main purpose of the reserve is to preserve the population of the Jersey tiger moth (Euplagia quadripunctaria). This species of butterfly is not endemic to Rhodes, but the valley is one of the largest sites of their summer concentration in Europe.
When and why butterflies appear here
The life cycle of these butterflies is tied to ivy. The caterpillars feed on ivy leaves, which grow in abundance in the valley due to the high humidity. Adult butterflies live only a few weeks and do not feed — their main task is mating and laying eggs.
From mid-June to mid-September, butterflies gather in the valley to reproduce. During the day, they sit on tree trunks and rocks in a state of rest. At night, they become active — they fly, mate, and lay eggs.
Important: the number of butterflies varies greatly depending on the weather of the previous season. In dry years, the population drops. Do not expect to see a "carpet of butterflies" — this happens rarely and mostly in years with good humidity.
Territory and routes in the Valley of the Butterflies in Rhodes
The total length of the tourist route is about 1 km one way (up the valley). There are two options for returning:
• The same road down — gentler, takes 15-20 minutes.
• The circular trail over the hill — longer and with a greater elevation change, takes about 40 minutes.
Along the way, you will pass:
• Lower part — wide trail, several wooden bridges, benches.
• Central part — small waterfalls (no higher than 1-2 meters), stone ledges, narrow passages between rocks.
• Upper part — viewing platform with a view of the valley and the monastery.
Kalambos Monastery
At the end of the valley, on a hill, is Kalambos Monastery, built in the 15th century. It is active, but no one lives there permanently — services are held by visiting monks from other monasteries on the island. Inside, there is a small church with frescoes (condition is average, partially lost), a courtyard with orange trees, and a well. The monastery is open from 9:00 to 18:00, entry is free (included in the ticket to the valley).
Best time to visit the Valley of the Butterflies
• June — beginning of the butterfly gathering, fewer of them, but also few people.
• July — peak number of butterflies, but also peak tourists.
• August — still many butterflies, but maximum heat.
• First half of September — butterflies still present, heat subsides, fewer tourists.
• Mid to late September — butterflies fly away or die, the valley is empty.
By time of day:
• 08:00-09:30 — ideal: cool, few people, butterflies more active.
• 10:00-14:00 — worst time: hot, crowds, butterflies stressed.
• 16:00-18:30 — second good option: the sun leaves the gorge, it becomes cooler, people leave.

Reviews and typical disappointments
"I only saw 10 butterflies!" — most likely, you came out of season (before June 20 or after September 15) or on a very hot day (the butterflies flew deep into the forest for shade).
"These aren`t butterflies, they`re moths!" — yes, these are nocturnal butterflies (moths). They are not bright or large. If you were expecting tropical swallowtails, don`t come.
"Too many people" — yes, from 10:00 to 14:00 this is a real problem. The only way to avoid it is to come at opening or after 16:00.
"I expected a valley, but it`s just a stream" — yes, it is a small gorge, not a wide valley. The name "valley" is a convention.
Weather and how it affects butterfly visibility
• After rain — butterflies do not fly, they sit tightly on the trunks. Visibility is good, but photography is difficult (dark).
• In heat (above 35°C) — butterflies fly deep into the forest where humidity is higher. There will be few of them on the route.
• On a cloudy, cool day (22-25°C) — ideal: butterflies sit in open places, some fly.
• In strong wind — butterflies hide in rock crevices, you will see only a few.

Summary: who should go to the Valley of the Butterflies in Rhodes and why

• You are willing to get up at 6 a.m. and arrive by 8:00 a.m.
