Great choice of Naxos. The island has so much to offer and your 12 days will be full of things to see and do.
How are you planning to get to Naxos. It can be reached by ferry from Rafina and Piraeus and is serviced by Sky Express and Aegean airlines. I always try to get to my first island on the day of arrival and leave Athens to the end of the trip. Certainly do make sure you are in Athens at least a day before your return flight. We always fly to get to Naxos as quickly as possible.
We like to find studio hotels with at least a hot plate fridge kettle, dishes and cutlery. This allows us to shop locally for breakfast food and morning coffee. We often have a Greek Salad with fresh Greek bread for lunch and always eat out for dinner. Watching sunset from a seafront bar and having late dinner is a wonderful experience on Naxos.
We love St George beach because it is part of Naxos town so we get a beach holiday and all the activities of town just a short 10 minute stroll around the headland. However since you will be there in August you might consider staying out at one of the west coast beaches for a few days until the bulk of the European crowds have to return for school and work. There are three very good beaches about 7km from Naxos town on the west side of the island. Our favorite is Plaka beach. It is at least 3km long and has nice sand. It is serviced by a string of hotels and tavernas. The further south you go the less infrastructure there is. We stay at Three Brothers hotel. Its close to the beach. Almost every room has sea view and it is well priced.
Recently we have been starting our vacation at Plaka and spend 3 to 5 days then head into St George beach for the town portion of our trip. There are several good small studio hotels at St George.
Exploring other islands. Paros is essentially the only close by island that can be done by regular ferry. Its just the way the ferry routes are set up. You can get to Paros in the early afternoon and return on the late night 10ish Bluestar. There are two excursion Boats Alaxander and Naxos Star. They both do full day trips to Santorini, Delos and Mykonos and the Small Cyclades Islands.
On Naxos there are lovely mountain villages where you will see what Greece used to be like. In particular we always go to Chalki and Aparanthos and Filoti. Last September winds kicked up making beaching not very nice and we took the KTEL bus to Chalki two days in a row for hikes. There is a round the island bus tour that is quite good.
Last September we found a new tour company that does small group programs max 7 people. Our tour was a visit to a Goat and Sheep farm where we fed the goats and made cheese and had a Greek farm lunch. Later we visited a winery and did rather generous 7 bottle wine tasting. Be sure to look for Philema tours. The owner Elaini designed several unique itineraries that included local farmers, wineries and olive oil producers and marble quarries. More on this tour in the next post.
