"Santorini is all about drama and dreaminess. Think whitewashed villages clinging to cliffs, sunsets that stop conversations, and a sea so blue it almost doesn’t look real. It’s the kind of place where I lose track of time—and that’s exactly the point."
I visited several Greek islands for the first time when I was sixteen. They left a lasting impression and my soul longs to go back. I’m sipping chilled Assyrtiko on a terrace in Oia, golden light dancing off the caldera, and the only decision left is which taverna to wander to next—right in the heart of Santorini. Who knew paradise could come with this much charm?
The best time to visit? From late April to early June and again in September through mid-October. The weather is warm but not scorching, the crowds are thinner, and the island feels like it’s yours to discover. During these shoulder seasons, you still get beach days, blooming bougainvillea, and golden hours with space to breathe.
Want peak summer vibes with lively nightlife? July and August bring the buzz, but also higher prices and packed viewpoints. For a quieter, more romantic escape, the early spring and fall months are ideal—mild weather, fewer cruise ships, and stunning views around every bend.

Travel Tips:
2. Getting to Santorini, Greece
Olympic Air provides daily service between Athens and the Monolithos Airport, Santorini’s airport. There are also chartered flights from other places in Europe as well as domestic flights to other Greek islands such as Crete. Aegean Airlines also flies daily between Athens and Santorini. Skala is Santorini’s cruise port: many people arrive in Santorini on cruise ships. It is an exposed port, so cruise ships anchor offshore and passengers are taken to the island on smaller boats. There is a ferry service from Piraeus, Athen’s port, to Santorini two times a day; there are also catamarans that are much faster. Ferries dock at Athinios on Santorini.
3. Getting From the Airport
Santorini has one form of public transportation and that is the local bus system. You can take a local bus from the airport to the main bus station in Fira, the capital of the island. The rental car agencies are located at the Arrival Halls at the airport: here you can rent a car to get into Fira and to visit other places on the island. There are many shuttle and taxi transfer companies that will take you into Fira or to any hotel or village on the island. It is a good idea to pre-arrange transportation if you choose not to rent a car at the airport.
4. Getting Around
One way to get around Santorini is by bus. These can be slow and infrequent, so the bus system is probably not the best choice for visitors who are in a hurry; but it is a great way to see the island and get from Fira to another village inexpensively. If you rent a car at the airport, you can drive around the island to see the attractions. Parking can be difficult in Fira and parking in a no-parking area will result in a steep fine. Many visitors enjoy seeing Santorini by moped. These are easy to rent but remember that you will be sharing the road with fast moving vehicles.
5. Restaurants
Many of the restaurants in Fira cater to visitors who spend just one night and then move on to another Greek island: the food at these restaurants is usually not as good as the food at the restaurants that are frequented by local Greeks and returning visitors. Corner Crepes serve breakfast and quick inexpensive meals; Lithos serves homestyle dishes at affordable prices; and Camille Stafani is a popular local taverna. If you want to venture out of Fira, check out the fish tavernas in Ammoudi which is Oia’s port. Katina is a fish taverna at the bottom of the cliff and, on the way down, Kastro serves fresh fish, pasta, and Greek dishes.
6. Shopping
Santorini is full of souvenir shops, but there are some other more interesting things to look for during your stay here. Kostas Antonious is the island’s best known jeweler; and Porphyra also offers beautiful jewelry creations. The Bead Shop sells pieces that are carved from the island’s lava while Nakis sells amber jewelry some of which have insects embedded in them. Some people go to Oia to buy wine: there is a large selection of wines here including locally produced Santorini wine. Other things to look for include Greek hand painted pottery; books at the Atlantis Book Shop; and pieces of sculpture at Mati Art Gallery.
7. Neighborhood Guide
Santorini is made up of several neighborhoods starting with the capital city of Fira. Here there are cobblestone streets, boutique shops, accommodations, and museums. Oia is a town about ten miles north of Fira and is known for its breathtaking sunsets. After an earthquake in 1956, the residents decided to rebuild their town by carving the buildings into the sides of the cliffs. The white-washed walls of the cave hotels attract photographers and honeymooners. Everything in Oia is more expensive than in Fira. The cities of Kamari and Perissa are known for their black sand beaches while Akrotiri is known for its red sand beach.
8. Getting Married in Santorini
Because of its spectacular beauty, Santorini is a very popular place for a wedding. Foreigners can get married in Greece: there is a fair amount of paperwork that is involved, but after you finish with all of this, it’s time to look for your perfect wedding venue. Some of the popular wedding venues include Le Ciel Santorini perched on the top of the caldera and featuring beautiful sunsets; the Theros Wave Beach Bar with its hidden southern beach location; Dana Villas in Firostefani with its fantastic wedding terrace and views; and the elegant Santorini Princess Hotel with its pool, open air lounge, and superb views.
9. Where to Stay
Santorini offers a wide variety of accommodations, from five star hotels to simple guest houses and inns. Some of its luxury properties include the Andronis Luxury Suites, the Canaves Oia Hotel, the Cavo Bianco, the Katikies Hotel, and many others. There are other special places to stay such as 1864 The Sea Captain’s House with it vaulted ceilings and weathered wooden floors; the family run nine room Astarte Suites located in the least-developed part of the island; the Canaves Oia Santorini set in a former 17th century winery; and the Chromata with its 26 colorful rooms and an infinity pool.
