Forming one of the Cyclades group of islands, the Greek island of Ios is located in the Aegean Sea and lies around mid way between the island of Naxos and the island of Santorini. The island's terrain is characterised by hills and cliffs that lead down to the sea on most sides of the island. Located on the north west coast is the island's port which is only a short distance from the village of Chora. The trip between Chora and the port can be made on foot which will take you along a steep donkey path, and takes around 15 minutes. The village is characterised by narrow paths and streets most of which have now been taken over by bars, restaurants, shops and night clubs to cater for tourists.
There are ferries from the island's port to Piraeus and Rafina with a crossing time of between 4 1/2 hours and 8 hours, depending on ferry type, route and destination. During the summer months Ios is also connected by ferry to the other islands of the Cyclades.
Kythnos is a Greek island that is located very close to Attica and is part of the Cyclades group of islands. The island, sometimes called Thermia because of the thermal springs on the island, is one of the lesser visited islands of the Cyclades but is popular with visitors because of its thermal springs. There is a modern spa located in Loutra, with two hot springs in the area. The spring of Ayio Anargyroi and the spring of Caucasus, where the temperature of the water reaches 52C, are famous for their therapeutic effects and have been since ancient times.
The island's harbour is located at Merihas and the island's capital is called Hora and are both located in the north of the island. In the south, only the areas by the bay of Ayios Dimitrios and Panayia Canála are inhabited. This is where a famous monastery is located within a pine forest.
Ferry services from Kythnos depart to the Port of Piraeus or to the port of Lavrio. The crossing to Piraeus takes approximately 3 hours by conventional ferry and approximately one hour by high speed ferry. The crossing time to Lavrio takes about 2 hours. Kythnos is also connected by sea with the islands of Serifos, Sifnos, Milos, Santorini, Sikinos, Folegandros and Kea.
