Another Volcanic island with spectacular rock formations and hot springs. Bikes or car useful if not essential. Slightly industrialized with mineral mines but don't let that scare you away. This is a beautiful island with fantastic beaches like Chivadolimni, Lagkada and Apollonia where you can take a boat to the island of Kimilos. The main village of Plaka is made up of the cubic white houses which the Cyclades are known for. The island is rich with archeological sites including Christian catacombs, a roman ampitheatre, Venetian castles and museums. Those of you who took art history should recall that the famous Venus de Milo was found here. For the story of my adventure in Milos click on the above link. Daily boats to and from Pireaus connect the island to Sifnos, Serifos and Kythnos. It's about a 7 hour trip to Pireaus. There are also 3 boats a week to Ag. Nikolaos in Crete and one or two a week to Folegandros, Sikinos, Ios and Santorini.
 
The very small island of Kimolos , accessable by daily ferry from Milos town of Polonia and by ferry 3 times a week from Pireaus is quiet, has excellent beaches, thermal springs and no gas stations.
