Enjoy a peaceful stroll along this pretty nature reserve. As the name implies, this green valley is home to hundreds of butterflies. Wander around waterfalls and along a river networked with wooden bridges, wherever you go beautiful butterflies flutter. Within the reserve, there is a trail to a monastery and the Museum of Natural History to explore too.

This massive, gothic castle is part of what makes the Old Town of Rhodes a UNESCO World Heritage Site. Built at the highest point of the medieval Old Town, the fortress dazzles with open courtyards, towering ramparts, turrets and fortifications. The imposing citadel offers splendid views of the island, and is also home to several works of art.

These unusual beaches only reveal themselves in low tide, connecting Prasonisi Islet with the main island. This long stretch of golden sand splits the Aegean and Mediterranean Seas, affording you the chance to swim in both, though ask anyone from Rhodes and they'll tell you to windsurf on the exposed western side, and swim in the sheltered eastern side.

One of Rhodes' most fascinating historical treasures, this Acropolis dates back over 3,000 years yet still leaves visitors standing in awe and wonder. The site includes many important monuments such as the Temple of Athena Polias and the Temple of Apollo. You can also see a gymnasium, an odeon and a stadium.
