The Acropolis in Athens
Regardless of whether you are a history buff, someone who enjoys looking at ancient architecture, or are just looking to explore some of Ancient Greece, this place is an absolute must during your visit. The Acropolis is one of the most visited places in Greece, and as such, you should expect crowds. But regardless of the crowds, it will be completely worth it for the unbeatable views. Pictures do not do the structure justice, and when you marvel at the size of the Parthenon you will understand why!
You Should Know
We also suggest purchasing an Athens city pass depending on how many days you will be in the city. The pass will offer you reduced tickets to this attraction as well as others and will get you into some completely free.
The Temple of Hephaestus
Located in the Thissio neighborhood of Athens, the Hephaestus Temple is said to be one of the most important structures in Greek history. Built by the same architect who designed the Parthenon the pretty columns and Pentelic and Parian marble decorations are what bring in the masses. This temple, as with all temples in Greece, was erected in the name of the Gods, and in this case, the God Hephaestus, who was the god of fire.
Best Time To Visit
We suggest visiting this temple during the day so that you are able to take in a natural beauty that surrounds it. It is also easier to travel during the day. The crowds will still be numerous regardless of the time of year.
You Should Know
Getting to the temple is simple enough if you take the metro to the Thissio neighborhood of Athens. From here it is just a 10-minute walk to the temple itself. While the entrance fee is 30 Euros, this cost will cover 5 days' worth of visits to multiple sites (similar to the Acropolis admission). There are a few restaurants in the area of the temple that you can stop at for a delicious lunch or dinner break.
Elafonisi Beach
Named one of the best beaches in the world, Elafonisi Beach is one that you need to see to believe. The beach has been named a nature reserve and is on the channel between the mainland and Elafonisi, an island famed for its unique pink sands and sand dunes. The water is clear and shallow and has a lagoon-like image. The sandbars make it possible to actually walk from the mainland to the island without even getting your feet wet!
Best Time To Visit
We suggest visiting the area during the early morning before 10 am. The sunrises over the beach are breathtaking, and the first group of visitors does not usually arrive at the beaches until around 10 am. 
Rethymno Old Town
The third-largest city in Crete has quite possibly the best-preserved old town on the island. The city was originally built behind walls, with tight cobblestone alleys laid on in the 14th century when Crete was in the hands of the Republic of Venice. In the heart of the city is the Neratze Mosque, which was originally a Venetian Church, before it became a mosque for almost 300 years. It is now Rethymno's municipal Odeon and is the stage for many concerts and performances. You will find all kinds of unique architecture in this beautifully preserved city.
Best Time To Visit
We would suggest visiting any time of the day. The city does not tend to get too crowded with people focuses more on tourist attractions. This little gem is something that needs to be seen but hasn't quite yet been recognized for its true beauty.
You Should Know
Being in one of the oldest cities in Crete means plenty of older thinking inhabitants. In this city, you will want to ensure that you are being extremely respectful of their culture and standards. We suggest sensible clothing, and nothing too revealing. When entering any of the older churches we suggest quiet reflection and conservative clothing styles. There are also plenty of restaurants in this city where you can enjoy some incredible local delicacies.
Ancient Acropolis of Lindos
Another Greek city, another Acropolis from the Ancient world. If you are looking to experience some rich Greek history then this is the place that you need to see. After settling into Lindos village follow the road that will lead you up a 116-meter high rock to see the Acropolis. Once there you can marvel at the ancient structures including walls, battlements, and a temple dedicated to Athena Lindia. You can immerse yourself in the monuments which truly makes you feel like you are experiencing every aspect of the Acropolis.

The acropolis does tend to get busy in the late mornings and afternoons, so we suggest visiting in the earlier morning hours before 11 am. Have a quick bite to eat in town and then head up to the acropolis for a few hours.

Santo’s Winery
If you are going to be on vacation then you might as well enjoy a few drinks while you're here, and we can't think of a better place than Santo's Winery in Santorini. At Santo's, you can try a wide variety of delicious Greek wines, along with plates of olives and other little bites to nibble. This would be the perfect way to spend a relaxing and lazy afternoon while waiting for your cruise to depart for its next port. You will get to enjoy a lovely view of Santorini while sipping those wines as well.

Alefkandra
Also known as Little Venice, Alefkandra is near the western tip of the Old Harbour. When you arrive you will notice that the area of Alefkandra is made up of a web of little car-free alleys. The alleys are lined with dark marble paving stones and painted in the same white paint as the houses in the area. The reason it is known as Little Venice is because of how close everything is to the water. Often sitting less than a meter above sea level is a slew of restaurants the have tables lining the seaside for glorious views.
Best Time To Visit
We suggest visiting this area at twilight. The sunsets on Mykonos are some of the most incredible sunsets you will ever see and watching that sun descend behind the windmills is truly breathtaking!
You Should Know
Being right on the sea can mean that you may get a little wet. The sea breeze can be unpredictable, as can the waves. We suggest checking the weather in the area before making the choice to venture too close to the water unless you don't mind a little splash!
Anyone you ask will tell you that the absolute best time to visit Greece is in the spring and early summer months (mid-April to mid-June), or in the autumn (September to mid-October). When visiting at these times you often avoid the summer high season, which comes with crowds of people and inflated prices. While lodging won't be a concern, Easter weekend can be pretty busy, and many museums and other tourist areas are closed for the entire weekend. You will also find that visiting in the spring and in autumn will provide you with some of the best weather. During the months of July and August, the temperatures can be unbearably hot and you might find yourself enjoying shelter indoors rather than exploring the areas around the ports.
