We highly recommend doing a free walking tour of Athens! This is a great way to see the city, often with a local tour guide. These tip-based tours combine a budget experience with a local perspective!
Explore Chora (Naxos Town) with its beautiful, classic Grecian whitewashed houses. Visit the Temple of Apollo, an ancient Greek Temple. Take a Village Road Trip through the various towns on the island. Hike Mount Zas for a beautiful sunset. Explore the Cedar Forest of Alyko. And of course...try the local cuisine!
Just a 30 minute ferry ride from Naxos, Paros island is another beautiful Greek Isle. If you have obtained an International Driving Permit ($20 from your insurance company), you can rent Quad Bikes and explore the island!
