The Santorini beaches are mostly along the southeast coast. A long black strip of volcanic sand runs from Kamari to Perivolos. This is a popular beach destination. On the western side of the island is the flooded volcano crater. It is one long crescent, almost a vertical cliff. There are a few beaches on the northeast side and southwest butt hey are very small. These beaches don’t have access to facilities like the beaches on the southeast coast. 

Santorini Sightseeing

There are many different attractions to visit in Santorini. Santorini itself is a beautiful, unique sight to behold. Santorini has beautiful churches built int the Cycladic style with whitewashed walls and blue domes. Visit the Monastery of Prophet Elias and get better acquainted with the rich cultural history of the islands. 

There are many great museums and archaeological sites. You can visit the ruins of the five Venetian castles and Akrotiri Lighthouse. Take in the majestic views, the beautiful water, and spectacular sunsets. 

 If you are traveling to visit the sights, the views, wineries, food and beautiful sunsets then you don’t need hot weather but pleasant weather. We recommend visiting in late March, April, May, October, and November. These are great times to visit the island. 

There may be light rain so pack a raincoat and some warmer clothing. The weather during these times is still considered warm and enjoyable by most standards. 

Santorini Island Hopping

Santorini has several diverse attractions making it possible to enjoy a vacation here outside of the main summer months. Add Santorini to your list of places to visit during your island-hopping vacation in March, April, early May, late October, and November. These quieter months are a great time to see the islands and miss the crowds. 

Other surrounding islanders are usually less crowded at this time as well so you can group a few together that you would like to visit.

If you are primarily looking for a great deal, consider visiting Santorini during the low season November through March. This is the best time to visit Santorini if you are on a tight budget.

If you want great weather and a cheaper hotel, travel in late May, early June, late September or early October. The first couple of weeks in October can surprisingly bring beautiful weather durian some years. 

To save money on travel to Santorini consider booking a flight to Athens and then taking a ferry to Santorini. The boats in Greece are comfortable and a safe way to travel on a budget. 

When you book a hotel on Santorini take a look at hotel options in Fira instead of the touristy city of Oia. Fira has great restaurants and bars. It may not be as “glam” as Oia but it is more affordable.
