Santorini Port: Cruise to Volcano, Hot Springs & Thirassia

Santorini’s best views are from the water. This six-hour cruise links three very different stops: the volcanic slopes of Nea Kameni, the warm waters of Palea Kameni, and quiet Thirassia. I especially like the mix of walking, swimming, village time, and a long sail beneath the cliffs. The onboard commentary adds useful context, and the roughly $41 price is excellent for a full day out. The main catch is that you need to be comfortable with uneven ground, steep steps, and a swim from the boat.

This is not a polished luxury cruise. It is an active, social boat trip with a set schedule. The hot-spring stop can feel short, and the water may be more warm than hot. Bring cash for the €5 volcano fee, wear shoes you can walk in, and put your swimsuit on before boarding.

Five things to know before you book

• The volcano hike is rocky but manageable: You can walk partway or continue toward the crater, with fine views across the caldera.
• The hot springs require a swim from the boat: Foam noodles are provided, but life jackets are reserved for emergencies.
• Thirassia offers two different outings: Eat beside the harbor or climb to Manolas for wider views and a quieter village feel.
• The return sail is part of the attraction: The route passes below Oia, Imerovigli, and Fira, revealing Santorini from a fresh angle.
• The value is unusually strong: At about $41 per person, the cruise includes transport on the boat, guiding, commentary, three stops, and six hours of sightseeing.

Starting at Fira Old Port at 10:15

The standard meeting point is the Santo Star office at Fira Old Port. You should arrive by 10:15 am for the 10:30 departure. The meeting place can be easy to miss, so allow extra time and look carefully for the office rather than expecting a large cruise terminal sign.

Getting down to Fira Old Port is part of the Santorini experience. You can use the cable car, walk down the steep path, or arrange another option. The cable car is listed at €12 each way, although some recent visitors paid €10, so keep cash ready and check the current price.

If you choose hotel pickup and drop-off, the arrangement changes. The cruise leaves from Athinios Port at 9:45 am, and pickup may be from a nearby walking point rather than directly outside your hotel. The operator sends the exact place and time before the trip. If that email has not arrived at least a day ahead, contact MTM Experiences and confirm everything.

The transfer option is worth considering if you are staying far from Fira or do not want to tackle the port access yourself. Several people found the transport punctual and easy, while the central meeting point works well if you are already based near Fira.

A sailing boat with room to watch the caldera

The boat is a comfortable sailing-style vessel with indoor seating, outdoor areas, and a roof deck on some departures. It can fill up, especially in the main season, but the boat has generally been described as clean and not overly cramped. I would claim a seat early if the upper deck view matters to you.

The boat has a small toilet and hand-washing facilities. The onboard bar sells drinks, including water, soft drinks, and other refreshments. Prices have generally been considered reasonable, and some departures have offered better-value drinks toward the end of the trip.

A guide travels with you, and the boat commentary explains the islands, volcanic activity, and caldera. Guides have included Roula, Gianni, Yannis, and Georgia on different departures. The quality of the guiding is one of the strongest parts of the trip: explanations are clear, friendly, and easy to follow without turning the day into a lecture.

The audio commentary helps when you are seated away from the guide or looking out from another deck. Music may also feature during the return sail, so expect a relaxed group atmosphere rather than a quiet private yacht.

Nea Kameni and the walk to the crater

The first major stop is Nea Kameni, the dark volcanic island in the center of Santorini’s caldera. Here you can pay the €5 entrance fee in cash and take the optional walk toward the active volcanic crater.

The route crosses rough, black-brown volcanic ground with little shade. It is not a technical mountain walk, but it is tiring in the sun and requires steady footing. Good walking shoes are far more useful than sandals, and you should carry water even though the boat has a bar.

The reward is the setting. Santorini’s white villages are famous, but Nea Kameni gives you the other half of the story: bare rock, craters, mineral colors, and the physical evidence of eruptions that shaped the island. From higher points, the view opens across the caldera to the cliffs of Santorini and the surrounding islets.

You do not have to complete every step. If the heat or footing becomes too much, walking partway still gives you the volcanic scenery. The group normally has enough time to explore without being rushed, though you should keep an eye on the guide’s return instructions.

This stop suits anyone who enjoys a little effort for a memorable setting. It is less suitable if you need smooth paths or frequent shade. The tour is not wheelchair accessible and is not recommended for people with walking disabilities or those using a stroller.

Palea Kameni and the swim to the warm water

After Nea Kameni, the boat moves to Palea Kameni for the hot-spring stop. This is the most unusual part of the day, but it also needs the clearest warning: you usually swim from the boat toward the thermal water rather than stepping straight onto a beach.

Foam pool noodles are supplied. They help non-confident swimmers stay afloat, but they are not a substitute for swimming ability. Life jackets are provided only in an emergency, so you should be comfortable in open water before joining the swim.

The warm water is not always as hot as the word hot springs suggests. Some people find it pleasantly warm, while others describe it as merely warmish. The stop can last about 30 minutes, which gives you time to swim but may feel brief once everyone has entered the water.

The water can also be brown or yellow from the minerals. Sulfur mud may stain a pale swimsuit, so wear a dark one that you do not mind marking. Put it on before boarding if possible. The boat bathrooms are small, and changing afterward can be awkward.

You may notice rocks beneath the surface in places, so follow the crew’s instructions and avoid rushing into shallow areas. If you are not a confident swimmer, you can stay on board and enjoy the view. Skipping the swim does not ruin the tour, especially since the volcano walk and caldera sailing are strong experiences on their own.

Two hours on Thirassia

Thirassia is the longest stop and gives the schedule a welcome change of pace. The island feels quieter and more traditional than the busy cliff towns of Santorini. At the harbor, you will find restaurants where you can order lunch independently, since food is not included.

You can keep things simple and eat near the water. This is the easiest choice if you want a relaxed meal, a short walk, or perhaps a quick swim to rinse off the mineral water from Palea Kameni. Local dishes, frappes, and baklava have all been popular choices, but prices and quality vary by restaurant, so take a moment to look at menus before sitting down.

The other option is to climb to Manolas. The route uses a long series of spiral steps and can feel harder than it looks after the volcano walk. In good walking condition, the climb may take around 10 to 15 minutes, but heat, footwear, and your pace make a difference.

At the top, you get broad views over the bay and back toward Santorini. Manolas is worth the climb if you want a village setting and a meal with a view. It is less rewarding if you are hoping for a large collection of sights or shops. Thirassia’s appeal is its quiet scale, not a packed list of attractions.

A traditional donkey ride to Manolas may be available for an additional charge, but it is not included and may not operate on every departure. Some departures have had no donkeys, leaving the stairs as the only route upward. I would treat the climb as the dependable plan.

Two hours sounds generous, but it goes quickly if you eat, climb, take photographs, and return to the harbor. If you choose Manolas, keep track of the boat’s departure time. A late lunch can turn the walk back into a hurry.

The best part may be the return sail

The cruise back is not simply a transfer. The boat follows the caldera shoreline and passes below Oia, Imerovigli, and Fira. From sea level, the cliffs show layers of volcanic rock and changing colors that are easy to miss from the road.

This is when the scale of Santorini becomes clear. The famous white buildings sit high above the water, while the dark cliffs drop sharply toward the caldera. You get a different view of the island from every bend in the route.

The return journey is fairly long, which some people love and others find slow after the final stop. I like it as a chance to sit down, buy a drink, and let the scenery come to you. On some boats, music and a lighthearted atmosphere turn the final stretch into a social finish.

A roof deck is especially useful here. Bring a hat and sunscreen, but also keep a layer handy if the wind picks up. Sunglasses protect your eyes from glare and dust during both the boat ride and the volcano walk.

Is $41 a good price?

For about $41 per person, this is one of the better-value ways to see Santorini beyond its main towns. You receive a six-hour boat excursion, a guide, commentary, the volcano stop, the swimming stop, Thirassia, and the return route below the caldera cliffs.

You still need to budget for several extras:

• The €5 volcano entrance fee, cash only
• Food on Thirassia
• Drinks from the onboard bar
• The cable car, listed at €12 each way
• Any donkey ride to Manolas
• Hotel pickup, if you select that option

The price is especially appealing compared with higher-cost private or sunset cruises. You do give up privacy and flexibility, since the boat follows a group schedule. Still, the range of activities makes the cost hard to fault.

Food is not included, but that is useful in its own way. You can choose a harbor restaurant on Thirassia rather than being tied to a set meal. Just remember that your two-hour stop includes both eating and exploring.

Who will enjoy this cruise most?

I would recommend it to you if you want to see the caldera from the water and prefer a day with several different activities. It works well for couples, families with older children, and active adults who enjoy a moderate walk followed by time on the boat.

Children must be accompanied by an adult. Infant seats are not available, and the uneven ground, open-water swim, and steps on Thirassia make this a poor fit for very young children or anyone who needs easy access.

You will get the most from the trip if you can walk on rocky surfaces, manage stairs, and swim without relying on a life jacket. If you dislike group tours, long boat rides, or fixed departure times, a private charter may suit you better, though it will cost much more.

Pack comfortable shoes, swimwear, a towel, sunscreen, sunglasses, a hat, beachwear, and cash. Wear your swimsuit under your clothes, use a dark color, and bring shoes with a firm sole.

Should you book it?

Yes, if you want a broad Santorini experience at a sensible price. The volcano gives you geology and exercise, the hot springs add a memorable swim, Thirassia provides lunch and village time, and the return sail delivers the caldera views that make the whole day worthwhile.

I would skip it only if you have limited mobility, are an uneasy swimmer, or want a quiet luxury cruise with no group schedule. For most visitors who want to get beyond Fira and Oia, this is a well-balanced six-hour outing. Just budget for the volcano fee, prepare for the steps, and keep your expectations realistic about the hot springs: the swim is often more enjoyable than the temperature.
