Situated on the picturesque island of Paros, 7 km to the west of Parikia and in close proximity to the Monastery of Christos sto Dasos, lies a place that has always been known as “Butterflies Valley” or “Petaloudes” in Greek . An idyllic landscape of dense vegetation and abundant spring water, “Petaloudes” is a unique monument of natural beauty.

Well-marked paths winding through the park make it easy to discover all that the Petaloudes has to offer.. The minimal entrance fee is a small price to pay to experience the idyllic setting and escape the heat.

During the months of June to September, swarms of butterflies named Euplagia quadripunctaria, or Jersey tiger moth, settle on this small oasis. They choose this place to spend the last phase of their life.
Resting on the leaves, they can be observed by the guests in their natural habitat. If you are lucky, you might catch them in flight, revealing the vivid red of the underside of their wings, which contrasts with their dark upper side.

For countless years, “Petaloudes” has been a haven for this species, granting it a unique essence. The gates opened to the public in the ’70s, enabling the visitors to relish in the beauty of the natural world. However, it’s crucial to remember that the reserve primarily belongs to the winged creatures. We kindly ask all visitors to be attentive to their environment and refrain from disturbing them in any way.


The valley in which you will find yourself has always been known as “Petaloudes”. This is indeed a true oasis as water comes into the valley from a natural spring all the year around.


Butterflies Nature Reserve is an ideal destination even for families as there is a small playground also ιn the area.


In the beginning of the reserve, we have created a cafe that is in complete harmony with the surrounding environment.
