Santorini – Volcano and Hot springs

Santorini’s volcano is closer than it looks. This three-hour boat trip gives you two of the island’s most unusual outings in one tidy morning: a walk across the active volcanic island of Nea Kameni and a swim near the warm waters of Palea Kameni. I like the low price of $36.01 and the efficient schedule, which works well when you have limited time. I also like the friendly crew, onboard restroom, and swimming noodles.

The main catch is physical. The volcano walk climbs over rough, slippery ground, and the hot springs require you to climb down a boat ladder and swim about 30 meters. The water may feel warm rather than truly hot, so you should book this for an active outing, not a relaxing spa visit.

• Two volcanic islands in three hours: You visit Nea Kameni and Palea Kameni without spending a full day at sea.
• A 1-hour-15-minute volcano stop: You have time to walk uphill toward smoking craters and look across the caldera.
• A short swim to the hot springs: The boat anchors in a small bay, but there is no beach or easy shoreline entry.
• A practical boat setup: An onboard restroom and swimming noodles make the trip easier.
• A low-cost Santorini option: At $36.01, this is a useful way to see volcanic scenery without paying for a longer cruise.
• Old Port logistics matter: You must reach the Fira Old Port, and voucher holders may need to redeem tickets at the booth before boarding.

What This Three-Hour Santorini Trip Actually Includes

This is an express boat outing with a clear purpose. You leave Fira’s Old Port at 11:00 in the morning, visit the volcano, stop for a swim near the hot springs, and return to the same port at about 2:00 in the afternoon.

I like this simple plan because it does not try to add a third stop or stretch the day with a long lunch. You spend most of your time seeing the two volcanic islands, not waiting around. That makes the tour a good fit if you have only part of a day in Santorini.

The boat carries up to 75 people, so this is not a private sailing trip. Still, the group size is reasonable for a short excursion, and the crew keeps the schedule moving. The boat itself has been praised for being comfortable and well kept, with an old-fashioned character that suits the setting.

You will need to bring your own lunch and snacks if you want them. Lunch, snacks, drinks, and transfers are not included. Water is available for purchase onboard, but there are no refreshments provided as part of the tour.

Finding the Boat at Fira Old Port

The meeting point is Santorini Excursions, Dakoutros Bros J.V., at the Fira Old Port in Ormos Firon. This detail matters more than it first appears. Fira sits high above the water, while the boat leaves from the port below.

If you are already at the Old Port, the ticket booth is in front of the boarding area and is marked Dakoutros Bros J.V. White cube benches near the booth can help you recognize the spot. If you arrive by cruise tender, the shop is easy to find once you reach the port.

If you are staying in Fira or coming from the upper town, allow time to get down to the port. A cable car ride may be needed, and you should not assume that reaching Fira means you have reached the departure point. One particularly useful tip is to check the exact meeting coordinates before leaving your hotel.

Some voucher holders have found that they needed to redeem the voucher at the Old Port ticket stand before boarding. I would handle this early rather than arriving at the last minute. The boat departs at 11:00, and the port is not the place to discover that you still need a paper ticket.

Nea Kameni: A Walk Across an Active Volcano

The boat reaches the small port of Erinia on Nea Kameni after about 10 minutes. The vessel remains there for 1 hour and 15 minutes, which is the longest stop and the main reason to bring proper shoes.

The path toward the craters is uphill and made of rough volcanic rock. It is not a mountain trek, but it is harder than a casual stroll. You may find parts of the route slippery, and the heat and sun can make the climb feel tougher. Several shaded rest points with umbrellas and seats help, but you should still pace yourself.

I would wear walking shoes or sturdy trainers. Flip-flops are a poor choice here. They can slide on loose rock, and they offer little protection from the sharp ground. Sunscreen and a hat are also sensible because the exposed path provides limited shelter.

At the upper part of the route, you can see active craters, smoky rocks, and the yellowish traces associated with sulfur. The smell of brimstone is strong in places. This is the valuable part of the stop: you are not just looking at a distant volcanic cone from the water. You are walking across ground that still shows signs of heat and volcanic activity.

The guide walks with the group and explains what you are seeing. Demetris has been singled out for his helpful, reassuring manner, and the crew has a good reputation for keeping people informed and safe. The guided walk gives the stop more meaning than simply wandering over black rock with no context.

Do not expect an easy path to the top. If you do not exercise regularly, the climb can be tiring. You can stop partway and wait, but that means you may miss the best views and the smoking craters. The allotted time is enough for the walk if you keep moving, but it is not generous enough for a very slow pace, long photo sessions, and a relaxed lunch.

The view from Nea Kameni is one of the strongest parts of the outing. From the volcanic slopes, you can look back toward Santorini and see how the island’s cliffs rise around the caldera. I would save your main photo time for the upper part of the path, then return to the boat with a little margin.

The volcano entrance fee is not included. You pay an additional €5 per person. That is a small extra charge, but you should budget for it because it is required for this stop.

Palea Kameni: Warm Water, No Beach

After everyone returns to the boat, you head toward Palea Kameni and the bay of St. Nicholas. This is the hot springs stop, and the boat stays for about 30 minutes.

The water temperature is listed at roughly 30 to 35 degrees Celsius, but it mixes with ordinary seawater. The result can feel pleasantly warm in parts of the bay, not like a hot bath. If you swim close to the shore and into the warmer area, you may notice more heat. The water is not evenly warm everywhere.

There is no beach. You enter from the boat’s ladder or jump from the side, then swim about 30 meters to reach the inner part of the bay. Swimming noodles are supplied, which is helpful, but they do not remove the need to be comfortable in open water.

This is the biggest practical limitation of the tour. The crew may advise anyone who is not a strong swimmer to stay out of the water. That safety warning is sensible, but it means the stop may not work for everyone in your group. Anyone who cannot climb down a ladder, jump into the sea, or swim to shore will probably spend the half hour watching from the boat.

The rocks near the warm water can be slippery and covered with algae. Keep your movements careful, and do not treat the area like a normal beach entry. The crew is attentive, but you remain responsible for judging your own ability.

I like that the swimming stop is short and clearly defined. You will not lose half the afternoon waiting for people to return. The drawback is that 30 minutes can feel brief once you account for getting into the water, swimming to the warmer area, enjoying it, and returning to the boat.

How Much Value Do You Get for $36.01?

At $36.01 per person, this is one of the cheaper ways to visit both volcanic islands from Santorini. The price is especially attractive if you want to see the volcano and hot springs but do not need a long sailing day, a meal, or a private boat.

You still need to add the €5 volcano entrance fee, and you pay separately for drinks or snacks. You also arrange your own way to the Old Port. Even with those extras, the cost remains modest for a three-hour excursion with a guide, boat transport between the islands, an onboard restroom, and swimming equipment.

The value depends on what you want from Santorini. If you are after dramatic coastal views, a short walk on active volcanic ground, and a quick swim, the price makes good sense. If you want a leisurely cruise, several swimming stops, or a long visit in warm water, you may find the schedule too limited.

I would also compare the cost with cruise-ship excursions. This trip can be appealing if the alternatives offered onboard are much more expensive or require an early morning departure. The 11:00 start leaves some breathing room, though you still need to allow time to reach Fira Old Port.

Who Should Book This Boat Trip?

I would recommend it most strongly to you if:

• You have about half a day in Santorini.
• You want to see an active volcano without booking a full-day cruise.
• You are comfortable walking uphill over uneven rock.
• You can swim in open water for about 30 meters.
• You prefer a low-cost, focused outing.
• You like having a guide explain what you are seeing.

Families and mixed-ability groups should think carefully. Most people can participate in the boat ride, and service animals are allowed, but the two main activities have real physical demands. The volcano path is uphill and sometimes slippery. The hot springs require a water entry from the boat.

The trip may not suit you if you dislike boats, cannot swim, have trouble with ladders, or want a calm spa-style experience. The crew supplies noodles, but this is not a supervised pool. You need to make your own safety decision before entering the water.

Practical Packing Advice for the Volcano and Hot Springs

I would pack light, but bring the right basics:

• Walking shoes or sturdy trainers
• Sunscreen and a hat
• Swimsuit and a towel
• Water
• A packed lunch or snacks
• A small bag that can handle a little sea spray

Do not wear flip-flops for the volcano walk. They may be fine on the boat, but they are not suitable for the uphill path.

The restroom onboard is a useful comfort, especially with a group of up to 75 people and no long break on land. The tour does not include lunch, snacks, or transfers, so plan around those omissions rather than expecting a full-service cruise.

Weather also matters. The activity requires good weather. If conditions force a cancellation, you are offered another date or a full refund. For cancellations on your side, you receive a full refund if you cancel at least 24 hours before the start time. Changes made inside that window are not accepted.

Final Recommendation: Is It Worth Booking?

I would book this tour if you want a short, affordable volcanic experience and are ready for a bit of effort. The volcano walk is the strongest part, with smoky rocks, sulfur smells, useful guiding, and wide views across the caldera. The hot springs are fun, but the swim is brief and the water may be only pleasantly warm.

Book it with proper shoes, a swimsuit, water, and realistic expectations. You are not getting a luxury cruise or a hot-water spa. You are getting a practical three-hour outing that lets you walk on an active volcano, swim near a volcanic bay, and return to Fira before the afternoon is gone.
