Caldera Yachting Santorini: Semi-Private Catamaran With a Thirassia Stop

Included in the $229.06

The listing includes lunch or dinner with seafood, grilled sausages, chicken fillet, salads and dessert, an open bar with white local wine, beer and soft beverages, a tour escort and host, commentary about Santorini during the cruise, printed safety instructions in 7 languages, the use of snorkeling equipment, towels and swimming aids, and a complimentary pickup and drop-off with an air-conditioned minibus or van. One honest note: the open bar pours wine, beer and soft drinks only, and no cocktails are mentioned. If cocktails matter to you, look at the listings that serve them instead of expecting them here.

How It Compares on Price

At $229.06 per person this is the most expensive shared catamaran in the comparison. The premium buys the smallest group size, up to 16 guests, and the Thirassia stop. If you want a small boat and Thirassia for less, Santorini Star Catamaran takes up to 18 guests for $111 with a seafood meal and an open bar with Prosecco.

If you would rather have the whole boat, Sail Away Private Catamaran is $944 for a private group of up to 4 from Vlychada Marina. For the sunset from Ammoudi with a full Greek meal at $171.79, see Santorini Day Tours Small Cruise. Figures are the catalog prices.

Pickup and Boarding at Ammoudi Bay

A driver collects you at your hotel in an air-conditioned minibus or van and drops you at Ammoudi Bay, the small port below Oia. Bring a passport or ID for every passenger, because a copy or photo is checked at embarkation, and passport details are required at booking. Printed safety instructions are on board in 7 languages.

Before the tour date, reconfirm your hotel with the operator to set the pickup time, which the listing does not state.

First Stop: Swim and Snorkel at Thirassia

The boat crosses to Thirassia, the quiet island across the caldera, for a refreshing swim and snorkeling in clear water. This is the opening stop rather than an afterthought, and it is the main reason to pick this boat. Snorkel gear, towels and flotation devices come from the crew.

The Volcano and Its Hot Springs

The boat sails on toward the volcanic islands and anchors near the hot springs, where you swim in geothermal water that is warmer than the surrounding sea. Two honest notes. You swim to the springs from the boat, roughly 50 meters across open water on other operators' briefings, so you need basic confidence in the sea.

The sulfur in the water can permanently stain light swimsuits, so wear an old or dark one.

Sailing the Caldera Cliffs, Then Dinner at Black Mountain

As the boat works along the caldera coastline the host explains the historical and geological events that formed Santorini's island complex, passing the pale cliffs and colored soil horizons. The meal is served at the hidden coves of the Black Mountain, with seafood, grilled sausages, chicken fillet, salads and dessert. Tell the operator any dietary requirements at booking.

White Beach, Red Beach and the Sunset Run

The boat sails close to White Beach, which has no road and is reached only from the water, and then past the red cliffs of Red Beach. Land access to Red Beach is closed because of rockfall, so the boat view is the safe and standard way to see it. On the sunset departure you watch the sun go down from the water before disembarking at the port of Vlychada on the south coast, where your transfer waits for the hotel drop-off.

Sunset times shift from about 17:05 in late December to about 20:40 at the summer solstice. The listing covers cancellation for bad weather.

Age Rules and the Confusion Around Children

The listing is contradictory. The age range is stated as adults 18 to 99, yet the details also say infants sit on an adult's lap and children must be accompanied by an adult. If you travel with children, confirm directly with the operator before you pay.

Travelers who want a cruise with clearer family age bands can look at Santorini Day Tours Small Cruise, which lists children from 3 to 4 and adults from 5 to 99.

The Price Itself

At $229.06 per person this is the most expensive shared boat in the comparison. If that is over budget, the big shared catamarans on the homepage start at $67 for the same 5-hour format with a barbecue and drinks, at the cost of 50 or more people on board.

Anyone Wanting the Volcano Hike or a Bigger Boat

The cruise does not include hiking on the volcano, and the listing names no landing on Nea Kameni. The crater walk needs a separate volcano tour with its own 5 euro cash landing fee. The group is capped at 16, so if you prefer a livelier deck, Comfort Max Catamaran caps at 50 for $67.

Wind, Weather and Cruise-ship Timing

The listing covers cancellation for bad weather. Cruise-ship passengers must give the ship name, docking time, disembarkation time and re-boarding time at booking, and the ship tenders to the Old Port rather than docking, so the timing has to work with your call. If the dates do not line up, browse all Santorini catamaran cruises for a boat that fits your hours ashore.

Ammoudi Bay, Your Departure Port

The boat leaves from Ammoudi Bay below Oia, which is reached by about 300 steps down from the town, so allow up to half an hour on foot if you skip the included pickup. The small boats to Thirassia leave from here too if you want to return to the island on your own. The Ammoudi Bay guide covers the port in detail.

The Vlychada End of the Sunset Run

The sunset cruise disembarks at Vlychada on the south coast, a working fishing harbor and marina about 10 km from Fira. If you decline the drop-off or stay nearby, the Vlychada Marina guide has the layout and the surrounding beach. If you arrive by cruise ship instead, note that ships anchor in the caldera and passengers tender to the Old Port, where the cable car to Fira costs €10 one way.

Adding the Volcano Crater Walk

This cruise does not land on Nea Kameni. If you want the crater rim, book a separate volcano tour, plan on about an hour on the island with a 20 to 30 minute climb, and bring €5 in cash for the landing fee. The Santorini volcano guide explains the walk.

Thirassia and Akrotiri on Your Own

If the Thirassia swim leaves you curious, small caique boats cross from Ammoudi in about 10 minutes in summer, several times a day. The Thirasia guide covers the island and the roughly 270 steps up to Manolas. On land, the Bronze Age town at Akrotiri is another add-on, and the Santorini hot springs guide tells you what to expect in that rust-colored water before you swim in it.
