Valley of the Butterflies, known locally as Petaloudes, is a unique and enchanting natural park located about 25 kilometers from Rhodes Town. This verdant valley is a nature lover's paradise, where a small river runs through dense, fragrant forests of Oriental sweetgum trees (Liquidambar orientalis). The area is famous for the thousands of Panaxia quadripunctaria moths (often called the Jersey tiger moth) that gather here from June to September, drawn by the sap of the trees.
The park features well-maintained wooden paths and stone steps that wind along the riverbank, leading visitors up the valley to a small monastery. The cool, moist environment is a stark contrast to the dry, rocky landscape of much of the island. As you walk, the gentle sound of running water, the rustling of leaves, and the distinctive, slightly sweet scent of the trees create a truly soothing atmosphere. The butterflies, with their striking black and white striped wings with a hint of red, often congregate on rocks and tree trunks, sometimes so densely that they appear to cover the surfaces.
At the top of the valley is the Monastery of the Virgin Mary of Kalopetra, built in 1784. It offers a picturesque resting point and a small museum. The descent provides a different perspective of the landscape. It's important to note that visitors are advised to be quiet and not to clap, as the vibrations can disturb the butterflies. This special place is a testament to the natural wonders of Rhodes and offers a peaceful escape from the busier coastal resorts.
