There is a small airport operating on Naxos island with daily flights to and from Athens. So while travelling from India, you will need to fly to Athens (or Thessaloniki, but this route is more expensive and less frequent) and then take a domestic flight to Naxos which has a travel time of only about 35 minutes. The airport is 2 km from the main Naxos town and is a convenient location to find public transport to get you to your hotel - anywhere on the island.
Greece's Cyclades island is popular with tourists from all over the world and hence there are many ferries and cruise ships that travel between the islands - more frequent during summer - but nevertheless available throughout the year. From India, you can fly to Athens and then take a ferry from Piraeus Port. The trip would take roughly 4 to 6 hours depending on the ferry operator you choose. You can also get to Naxos from other Greek islands like Mykonos, Santorini, Paros, Koufonisia and Amorgos. The port is located in the main town of Naxos.
Naxos sees plenty of visitors all year round and hence is a very tourist-friendly island. Their bus service runs smoothly for tourists to get to different parts of the island with no trouble - they run every half hour in the summer and every hour in low tourist seasons.
