Getting around Mykonos can be challenging, especially during peak season. Hiring a car or scooter is the most convenient option, but it can be expensive. Alternatively, you can take the public bus which runs regularly between Chora, Paradise Beach, and other popular spots on the island. Be prepared to pay around €1.80-3 for a single ride and factor some extra time for waiting and delays.
If you have more time, consider adding a visit to the nearby island of Delos, home to some of the most significant archaeological sites in Greece. Alternatively, if you have less time, you can skip some of the sights or combine them into a shorter itinerary. Keep in mind that Mykonos can be overwhelming during the high season, so it's best to book your accommodation and activities well in advance.
