For the traveller, Rhodes City falls into four more or less distinct areas. The most important by far for most visitors is Rhodes Old Town, still enclosed by its medieval wall. Rhodes New Town, north and west of the Old Town, is an extensive and fairly non-descript modern city. The New Town's eastern waterfront, comprising the Commercial Harbor, the yacht and ferry Mandhraki Harbor, and extensive Elli Beach may count as separate area. Finally, the Acropolis of Rhodes, the ruins of the ancient city, are about 2 km southwest of the Old Town.
The local tourist information office for the Dodecanese Islands is located in Rhodes city at Makariou & Papagou Corner. Telephone 22410 44335-6, Fax 22410 26955.
The only airport of the island is the Diagoras International Airport. From there, you can reach Rhodes city with a bus, car or taxi.
There are regular ferries from the mainland and the islands. Also, there are regular ferries from Marmaris, Turkey. http://www.marmarisferry.com/index_en.php
In the Old Town, the primary method of travel are your feet :)
Rhodes Old Town, a UNESCO World Heritage Site , is one of the best preserved and most extensive medieval towns in Europe. It iss also the location of many monuments and several museums - make sure to get a good map. If you want to see it all, plan for at least a day, and two will not be amiss if you want to see all the museums.
The museum operates a tour of the city walls Tuesdays and Saturdays at 8 am leaving from the Palace of the Grand Masters. This is not really a guided tour: visitors are simply allowed up on the walls to walk along the top of them at their own pace. This walk offers views of the town not otherwise available and is the best way to get an idea of the size of the town and the variety of its architecture.
Mikes (which is not the name Mike's but a Greek name prounounced MEE-kehs) is a hole-in-the-wall place (though with outdoor seating) in a tiny lane near 17 Socratous Street, which serves fish, salad, and wine, and not much else. A very simple restaurant but pleasant, and the seafood is of impeccable quality and well though simply prepared. A good budget choice in Old Town.
Hatzikelis Solomou Alhadef 9 tel +30 22410 27215 is one of the best tavernas, serving innovations on traditional Greek dishes; the stuffed, roasted eggplant is notable.
Laganis Solomou Alhadef 16 is a more traditional taverna with good mezedhes.
The Turkish Cafe at 76 Sokratous is a rare, wonderfully atmospheric survival of old Rhodes in the middle of the tourist hordes. Run by a charming couple, it serves excellent coffee and a small range of other drinks, but not much food except for a few snacks.
