Santorini is one of the most photographed destinations in the world — those whitewashed buildings, blue-domed churches, and magical sunsets fill Instagram feeds daily. But here’s the truth: what you see on Instagram and what you experience in real life can be two very different things.
So many travelers arrive expecting a dreamy, romantic getaway, only to be surprised by crowds, long lines, and little details they wish they had known ahead of time. Santorini is every bit as beautiful as the photos — but only if you plan smart.
To help you avoid the common pitfalls, here are the top mistakes to avoid in Santorini (and what to do instead).
1. Not Planning Around Cruise Ship Schedules
In peak season, thousands of cruise passengers flood the island at once, especially in Fira and Oia. You can avoid the crowds in Santorini by strategically planning your itinerary around the cruise port schedule. For more details on planning your itinerary around the cruise port schedule, check out my post on How to Avoid Crowds in Santorini.

2. Staying in Oia If You Don’t Like Crowds
Oia is Santorini’s most famous town, but it’s also the busiest part of the island. The crowds are so large in Oia that you will likely be walking shoulder to shoulder with people down the narrow alleys. Some hotel room patios are located right on busy walkways, with crowds walking right by your room. (So important to read hotel reviews for this reason!)
If you want a quieter base with the same caldera sunset and blue dome views, consider staying in Imerovigli instead. You’ll still be close to the highlights but with far fewer people outside your door.

3. Trying to Watch the Sunset in Oia Without Dinner Reservations
The Oia sunset is world famous—and that means it’s crowded. If you try to watch from the castle ruins or the main walkways, expect to be shoulder-to-shoulder with hundreds–even thousands–of other people. Personally, there are only two places I would watch the sunset in Oia: from a private hotel balcony or from a dinner table with a reservation. It’s the only way to really enjoy the view without the chaos. If you want to know the best spots, check out my blog post on the top sunset view restaurants in Santorini.
4. Not Checking Out the Beaches
Santorini’s beaches aren’t the powdery white sand you might picture in the Caribbean — instead, they’re volcanic, dramatic, and absolutely worth visiting. Kamari and Perissa both have beach clubs with sunbeds for rent, plus plenty of seaside restaurants and shops.
One of the best ways to explore is by taking the hop-on, hop-off water taxi, which stops at the Red Beach, White Beach, and Black Beach — it was truly one of our favorite experiences in Santorini.
The beaches in Santorini are rocky, so bring water shoes, and if you enjoy the water, consider packing a snorkel mask — we loved exploring the sea caves along the coast.

5. Not Being Prepared for the Hike from Fira to Oia
The hike from Fira to Oia is one of the top things to do on the island, but it’s not something you want to just “wing.” You’ll need to come prepared: wear sneakers (not sandals), pack plenty of water, sunscreen, and a hat — and start early in the morning to avoid the midday sun.

6. Assuming All Hotels On The Caldera Have Sunset Views
Santorini’s caldera faces west, which means it does get the sunset. However, depending on how your hotel is situated, the view might be angled or off to the side rather than a direct sunset view. If having that picture-perfect sunset is important to you, be sure to read hotel reviews carefully and look for guest photos of the actual view to avoid disappointment.

7. Wearing the Wrong Bathing Suit for the Hot Springs
The volcanic hot springs near Nea Kameni are rich in minerals that will stain light-colored fabrics. If you are taking a boat tour that includes swimming in the hot springs, be sure to pack a black or dark bathing suit for that day.

8. Not Having a Plan for a One-Day Cruise Visit
Arriving by cruise in Santorini can be chaotic. Between getting from the port up to town (ride a donkey or wait in long cable car lines) and trying to make the most of your limited time on the island, it’s important to have a plan — this is not something you can just “wing.”
If you’re arriving by cruise, consider booking a tour or planning an itinerary in advance so you can enjoy the highlights without stress.

9. Not Bringing a Voltage Converter
Greece uses 220V and Type C and F outlets, whereas the U.S. uses 120V and Type A and B outlets. If you’re traveling from North America or elsewhere, you’ll need either a voltage converter or dual-voltage electronics like hair tools. Most phones, tablets, and laptops are fine without a converter, but other electronics — like clothes steamers, and curling wands, or other hair tools — will need a converter or must be dual-voltage.Don’t plug a standard U.S. hair dryer directly into a Greek outlet — it will fry your device, leaving you without a way to do your hair for the rest of your trip!
Important things to note:
A voltage converter is different from an outlet adapter. Most voltage converters also work as adapters, but most adapters alone are not converters.
Read reviews for converters — some travelers report that their hair tools still fried. If you’re worried, consider buying dual-voltage hair tools like this dual-voltage hair dryer or dual-voltage flat iron.
Some dual-voltage hair tools require a screwdriver to switch settings. Make sure to adjust them before you travel.

10. Skipping Traditional Greek Villages
Santorini isn’t just about the famous caldera towns like Oia and Fira. Villages like Megalochori, Pyrgos, and Akrotiri offer authentic charm, fewer crowds, and a chance to see a quieter side of island life. Be sure to add at least one of these charming villages to your Santorini itinerary.

11. Not Booking Hotels, Tours, and Restaurants in Advance
Santorini is one of the most popular destinations in Greece, which means accommodations, tours, and restaurants can fill up quickly — especially during peak season. Waiting until the last minute will limit your options and cause you to miss experiences you’ve been looking forward to.
Plan ahead by booking your hotels, tours, and any must-visit restaurants well in advance to make sure you get the best spots.

12. Not Being Mentally Prepared for the Crowds
No one wants to spend a lot of money on the vacation of a lifetime only to be disappointed. If you’re expecting Santorini to be a peaceful, relaxing, romantic getaway but stay in Oia or Fira, you might feel overwhelmed by the crowds.
Even if you choose a quieter town, be prepared for crowds when visiting Oia and Fira — especially at sunset. It will be busy, but with the right planning and expectations, you can still have an unforgettable experience. Go in with realistic expectations, and you’ll enjoy the island’s beauty without frustration.

Final Thoughts
Santorini is one of the most beautiful places in the world, but it’s also one of the easiest places to get caught up in mistakes that make your trip less enjoyable. By planning around cruise ship schedules, booking the right hotel, making dinner reservations in advance, and preparing for experiences like the Fira-to-Oia hike or the volcanic hot springs, you’ll set yourself up for a much smoother (and dreamier) trip.
