Sailing through the caldera of Santorini at golden hour is the kind of Greek Island experience that feels dreamlike even as it's happening. On my first full day in Santorini, I joined a sunset cruise that began with a hike up Tholos Naftilos volcano, followed by a swim in the mineral-rich waters of Palea Kameni's hot springs.
As the sun descended, we drifted toward Amoudi Bay, where Oia and the cliffs glowed in fiery hues, and the sun dropped into the Aegean Sea. The five-hour sightseeing tour was a budget-friendly blend of adventure and relaxation. Based on my experience, here's what you can expect from a typical sunset cruise in Santorini.

Cruise Itinerary
Departing the Old Harbor
On my first morning in Santorini, I bought a ticket for a sunset cruise aboard the Thalassa yacht, which departs daily from Fira ($63 or €58). Thalassa is a replica of a brigantine, a two-masted vessel that dates back centuries.
I took the Santorini Cable Car ($11 or €10 one way) to reach the 89-foot-long wooden sailboat in the Old Harbor at the base of the cliffs. The alternative is a 30-minute walk down a zigzagging trail covered in donkey dung. The donkeys ferry tourists up and down the trail for a similar fee, but I suggest waiting in line for the cable car instead.
At 3:30 p.m., our ship set sail with 90 passengers aboard. Looking back at Fira from the water puts the town's precarious position in perspective. We spent the first 10 to 15 minutes of our Santorini sunset cruise motoring west to Nea Kameni Island.
Santorini's History
Santorini emerged dramatically around 1600 B.C. after one of history's most powerful volcanic eruptions reshaped the landscape.
The massive explosion caused the island's center to collapse, forming its crescent shape and cliffs. Volcanic activity has continued to shape the region, creating geological features like the caldera and hot springs.
Archaeological evidence reveals human presence as early as the 4th millennium B.C., with advanced Minoan settlements like Akrotiri flourishing around 2000–1600 B.C.
Despite earthquakes and volcanic eruptions throughout history, Santorini's residents adapted, building whitewashed villages along the volcanic cliffs and creating the captivating landscape visitors admire today.

Hiking Tholos Naftilos Volcano
Once our boat was secured in tiny Erinia Bay on Nea Kameni Island, we disembarked and began walking with a guide on a rocky trail to the craters of the Tholos Naftilos volcano.
The sulfur smell was noticeable but not overpowering, and seismic equipment was visible on the ground to monitor geologic activity. The walking trail makes a loop around the craters, and my favorite view was from the western side, with slivers of the white buildings of Fira visible in the distance.
On the walk back to the boat, the human development of Santorini and the cruise ships became clearer. We were off the boat at Nea Kameni Island for a little over one hour.
Wear or bring closed-toed footwear to protect your feet from the sharp volcanic rocks. And as there's no shade, proper sun protection (hat, sunscreen, sunglasses) is vital. I was visiting in mid-July, the hottest time of year in Santorini, but it was still a worthwhile excursion.
Hot Springs on Palea Kameni
Next, we motored to the hot springs at Palea Kameni, a smaller island off the west coast of Nea Kameni. The hot springs are the result of magma beneath the surface. Swimming is optional here, and a few people on our cruise had come prepared with bathing suits and towels.
It's recommended that you don't wear white because the minerals in the water could stain your clothes, and you should take off any jewelry to avoid damage from the heat.
On my Santorini sunset cruise, I was content to skip the swimming and watch others from the deck of the Thalassa. The tiny white building watching over the warm waters is Saint Nicholas Church.
Swimming at Therasia and Dinner
We left Palea Kameni and motored north and west toward the larger island of Therasia, where guests could swim in clear, calm waters.
Meanwhile, the crew was preparing our dinner of Greek meze (appetizers). Think chicken skewers, salads, sides, and bread. There was more than enough food for everyone.
Guests must pay out of pocket for drinks during the sunset cruise. However, everyone receives a complimentary glass of Santorini wine with dinner.
Sunset from Amoudi Bay
As afternoon shifted to early evening and the sun dropped toward the horizon, we sailed to the northern tip of Santorini. We saw Amoudi Bay, its small port, and the town of Oia above it, basking in the sun's orange glow. There was nothing left to do but relax and enjoy the colorful climax of our sunset cruise in Santorini.
The three-masted sailboat we'd been seeing all afternoon had raised its sails and looked quite attractive. Our ship did as well for the cruise back across the caldera to Fira, as a saxophone player casually played music on deck.
This sunset cruise captured everything I'd hoped for in Santorini—breathtaking views, fascinating geology, and moments of pure relaxation. From volcanic hikes and natural hot springs to a Greek dinner aboard a sailboat at sunset, each experience deepened my understanding of this island.
