Santorini, the crescent-shaped gem of the Aegean Sea, is one of the most captivating islands in the world. Famous for its whitewashed villages, iconic blue domes, and dramatic caldera cliffs, this Greek island also hides some of its greatest treasures offshore. Exploring Santorini by boat offers an entirely new perspective—one of plunging cliffs, hidden beaches, volcanic wonders, and the sparkling expanse of the Aegean. Whether you’re seeking a romantic sunset sail, a luxurious private yacht cruise, or a fun-filled catamaran day trip, Santorini’s boat tours provide unforgettable experiences for every type of traveler.
Why Explore Santorini by Boat?
Santorini is an island best appreciated from the sea. The unique crescent shape, formed by a massive volcanic eruption in the 16th century BC, becomes fully visible only from offshore. Cruising along the caldera allows you to witness the island’s dramatic cliffs rising vertically from the sea, topped with postcard-perfect villages like Fira, Imerovigli, and Oia. You’ll also gain access to spots that are otherwise unreachable—secluded beaches, the volcanic islets of Nea Kameni and Palea Kameni, therapeutic hot springs, and hidden coves. On a boat, you escape the crowds, breathe in the sea air, and enjoy the magic of Santorini on your own terms.
Types of Boat Tours and Cruises in Santorini
Boat trips in Santorini cater to a range of interests and budgets. Options include shared catamaran cruises, private luxury yacht charters, traditional wooden sailing boats, and even high-speed RIB tours. Most trips last between 5 and 8 hours, although shorter and multi-day itineraries are also available. Here’s a breakdown of the most popular types:
1. Catamaran Day Cruises
Catamaran cruises are among the most popular ways to explore Santorini by sea. These modern, stable vessels offer comfort, ample deck space, and excellent sailing performance. Most catamaran cruises follow a similar itinerary: departure from either Vlychada Marina (south) or Ammoudi Bay (north), stops at Red Beach and White Beach for swimming and snorkeling, a cruise around the caldera, a visit to the hot springs near Palea Kameni, and views of the volcano. Some tours include a BBQ lunch or dinner onboard, along with unlimited drinks. Morning cruises are great for sunbathing and swimming, while sunset cruises are perfect for romance and photography. Notable companies offering catamaran tours include Spiridakos Sailing Cruises, Sunset Oia, and Caldera Yachting.
2. Private Yacht Charters
If you’re seeking exclusivity and flexibility, a private yacht charter is the ultimate way to experience Santorini by boat. You can choose from motor yachts, sailing yachts, and catamarans, with options ranging from a few hours to full-day or multi-day charters. Private tours allow you to customize the itinerary—whether that means visiting lesser-known beaches, spending more time snorkeling, or arranging a gourmet meal on board. Many yachts come with a crew, including a captain and chef, ensuring a premium experience. This is an ideal choice for honeymooners, families, or groups celebrating special occasions.
3. Traditional Wooden Boats
For a more authentic Greek experience, hop aboard a traditional wooden “kaiki” sailing boat. These charming vessels offer a nostalgic feel and often operate semi-private or small group tours. Some follow similar routes to catamarans, while others offer special themed excursions, such as wine-tasting at sea or sunset dinners with live music. The pace is slower, allowing you to relax and truly absorb the scenery. It’s also a more affordable alternative to private yachts while still offering a personalized feel.
4. Volcano and Hot Springs Tours
Santorini’s volcanic history is central to its identity, and a dedicated volcano tour is a must for those interested in geology, history, or adventure. These tours typically depart from the Old Port of Fira and include a boat trip to Nea Kameni island, where you can hike to the volcanic crater. The terrain is otherworldly—black lava rocks, sulfur vents, and panoramic views of the caldera. After the hike, the boat heads to Palea Kameni, where you can swim in the thermal waters that range between 30°C and 35°C. The sulfuric mud is said to have therapeutic properties for the skin. These tours are often run on traditional wooden boats and last around 3 to 4 hours.
5. Sunset Cruises
Sunset in Santorini is legendary, and watching it from the deck of a boat is a magical experience. These cruises typically start in the late afternoon and last until after the sun has dipped below the horizon. Some sunset cruises follow a similar route to the day tours, with swimming stops and a visit to the hot springs, followed by dinner and wine on board. Others focus solely on enjoying the scenic coastline and the sunset, often with champagne and soft music to set the mood. Watching the sun sink behind Oia, with the cliffs turning golden and the sea bathed in pink, is an experience you’ll never forget.
6. Multi-Island Sailing Adventures
For those who want to explore beyond Santorini, multi-island sailing trips are a fantastic option. These longer tours, which can range from one day to several days, often include stops at nearby Cycladic islands like Ios, Folegandros, Anafi, or even Naxos and Paros. You can either join a small group sailing tour or charter a private yacht for a personalized itinerary. These trips are ideal for sailing enthusiasts or travelers wanting to explore more remote and untouched locations in the Aegean.
Top Departure Points for Boat Trips
Santorini has several key departure points for boat tours:
-
Vlychada Marina: Located on the southern coast, this is the most common departure point for catamaran and sailing cruises. It offers easy access to Red and White Beaches.
-
Ammoudi Bay: Located below Oia, it’s a picturesque port and a popular starting point for sunset cruises and private charters.
-
Athinios Port: While primarily the ferry terminal, it’s also used for some private charters and larger cruise ships.

Old Port of Fira: Accessible by cable car or footpath, this historic harbor is the starting point for most volcano and hot springs tours.
What to Pack for a Boat Trip in Santorini
When preparing for a boat trip in Santorini, pack light but smart. Essentials include swimwear, a towel, sunglasses, a wide-brimmed hat, reef-safe sunscreen, and a light cover-up for sun protection. Don’t forget your camera or phone for photos, and if you’re prone to motion sickness, consider taking precautions like Dramamine or wristbands. Most cruises provide snorkeling gear, food, and drinks, but check in advance to see what’s included.
Best Time of Year for a Boat Tour
The best time to enjoy a boat tour in Santorini is from late May to early October, when the weather is warm, the sea is calm, and the days are long. July and August are peak tourist months, so boats can get crowded—booking in advance is strongly recommended. For a quieter, more intimate experience, consider visiting in the shoulder months of June or September. During these months, the weather is still ideal, and the sunsets remain just as enchanting.
