Begin your journey from the port and set sail to the remarkable Nea Kameni Volcano, a captivating destination that showcases both active and inactive craters. Enjoy a guided hike to the top for panoramic views of Santorini's iconic Caldera. Next, visit Palaia Kameni, home to naturally warm Hot Springs, where you can swim in mineral-rich waters and experience the rejuvenating volcanic mud baths. The boat will pause near the small bay of Agios Nikolaos, giving you ample time to take in the unique environment and enjoy a refreshing swim.
Continue your adventure to Thirasia Island, where two hours of free time allows you to explore, swim in the crystal-clear waters of Korfos, and dine at charming local taverns while capturing stunning photographs of the island’s picturesque bay. On the return journey, sail along the dramatic volcanic cliffs of Oia and the Caldera, offering unforgettable photo opportunities of the breathtaking scenery. Finally, a bus transfer from Athinios Port takes you to the traditional village of Oia, where you can wander its narrow streets and witness the world-famous sunset, creating memories that will last a lifetime.

We had a private catamaran half day tour and it was perfect and magical! The crew was helpful and welcoming! The boat luxurious and spacious! The food was delicious and the swimming stops were lovely! They were very good with our food allergies :) a must!!!

We joined Sunset Oia for a Luxury Catamaran Day Trip around the caldera and it was one of our favorite experiences in Santorini. Getting there was easy — after tendering ashore, we rode the cable car up to Fira and met our transfer right on time. (Tip: Grab coffee and pastries at Svoronos Bakery next door while you wait!) The check-in process at the marina was impressively organized — guests are grouped by color-coded tours, and the staff were professional, friendly, and efficient. The catamaran was spotless, the crew engaging, and the itinerary covered all the highlights: Red Beach, White Beach, and the volcanic hot springs. The onboard meal was fresh and plentiful — grilled skewers, Greek salad, dolmadakia, and local wine flowing freely. The mix of scenery, swimming, and relaxation made for the perfect Santorini day. Truly a first-class experience with a team that knows how to blend hospitality and precision.

Love love LOVED our Sunset Oia experience. We booked for two on Viator after literal weeks of deliberation on whether or not we should spent that amount of money for a sunset cruise (approx $145 USD each), not platinum booking, just regular. This trip was our favorite thing we did on our 2-week Greece vacation and possibly ever. - The staff was so kind and accommodating, we felt so taken care of before we even stepped foot on the boat to when it was time for us to be dropped off to our hotel by the Sunset Oia driver. - The boat itself was bordering the definition of luxurious, and very clean. - They did not overbook the catamaran and there was lots of space on board with the other passengers to where it felt basically like a private booking. So amazing!! - Locations were calm, and not overcrowded. When we went to swim there was only about 1 other boat in the waters, and it was the weekend. - Food was plentiful. Buffet style with options for seconds including the full-size protein options. It was also delicious. Top 3 foods we ate in Greece. So worth it I would go back to Greece and Santorini just to do this everyday. lol!

Beautiful catamaran, friendly crew! We had the best time and the lunch that was served was magnificent! We would love to take another trip! The swim spots were so unique and the captain positioned the boat for a most amazing sunset! Loved every minute of our trip!

I cannot recommend Sunset Oia Cruises enough — this was the highlight of my trip to Santorini! ⭐⭐⭐⭐⭐ (POV of a Solo female traveller.) Pickup was seamless, with a comfortable, air-conditioned van and wide seats (even at 300 lbs, I fit perfectly). Our driver was safe and professional. We did the morning tour, which I *highly* recommend over sunset — vehicle and pedestrian traffic for sunset was horrendous as we were leaving. All communication beforehand was prompt and kind, as well as easily accommodating. The boat was spacious and clean, with three swim stops and an absolutely delicious buffet lunch — fresh, high-quality, and way more than enough food for everyone! (Souvlaki of chicken/pork/veggies; dolmas; tzatki/greek salad without fillers like lettuce; pita) Drinks like water, soft drinks, and white wine are included but beer is €4 and cocktails are extra. They only accept cash. > One small suggestion: ginger ale would be a great addition to the drink menu, especially since ginger helps calm seasick stomachs. The crew worked hard, but Fotini was truly exceptional. She was constantly working while other employees took breaks or sat on their phones; and she handled even the most absurd and entitled guest behavior (“Can you calm the waves? Can you turn off the wind?”) with grace and professionalism. She was not only proactive but a natural leader — solving problems before they even arose. If I still owned my company, I would immediately hire Fotini — even if it meant paying for her visa sponsorship, flights, and accommodations, to move to Canada. Her work ethic and dedication are priceless. Companies spend huge amounts of money trying to train and build employees like her, but with Fotini, these qualities are simply who she is. Sunset Oia is very lucky to have her, and they should do everything they can to keep her. If tips are shared, she’s the one who truly earned them. **Advice for future guests:** -Reapply sunscreen after every swim — many people didn’t and ended the day painfully sunburned. -Bring aloe vera, extra towels, a waterproof phone pouch, and a portable charger. -In case you get seasick, bring medication with you. I didn’t think I’d need it, but I really wish I had brought it. Incredible value, unforgettable experience, and a crew that truly cares — especially Fotini. 🌅
