Due to unforeseen weather, ferry schedule and other conditions, the itinerary can undergo modifications on location. In particular, the order of excursions or days mentioned can be changed.
Day 1: Arrival on Santorini

The hotel Akrotiri

The hotel Acrotiri

The hotel Acrotiri
Arrival at the airport of Santorini JTR and transfer to the hotel in the beautiful village of Akrotiri. Meeting in the evening for a dinner and a first introduction to the island and our tour. If you arrive early that day, you will have time for a first stroll at the beautiful coast of Akrotiri, red beach or even the fields around.

Day 2: The Minoan excavation and the caldera walking

The golden ram from Acrotiri

The cliffs of the Santorini caldera

An old volcanic vent near Ia village
To understand the importance of the prehistoric volcano and its impact in the prehistoric culture, we start with an visit of the spectacular Minoan excavation site and discover the items, that were found, in the museum of prehistoric culture in Thira town. There we can understand, how the arts and culture of this island was forming in thousands of years until it was cut by the disastrous volcanic explosion 1627 B.C. After this historic introduction, we will stroll through the modern, touristic town of Thira and along the caldera cliffs. After a while we will leave the "touristic" sector of Thira, Firostefani and Immerovigli. The first volcanic items are our target. There are many geological interesting sites with lava, ash and former volcanic dykes. We will have a nice brake in a café and on top of one of the older volcanic cinder cones we will enjoy the sunset at a picturesque chapel over viewing Ia village.
Day 3: Red Beach & Akrotiri peninsula

The village Akrotiri

The famous red beach

The volcanic intrusion
Akrotiri is not only famous for its excavation, but also for its picturesque "red beach", which was an old volcanic cinder cone. It is the first point of interest on our tour. We will hike up to the mountain and follow an old path to a valley with an impressive volcanic intrusion. At another one, that created a hill, we will have a break at a nice chapel. Later over some vine fields we will get to one of the best traditional taverns on Santorini with tasty local food.
Day 4: Boat trip to the volcano islands

The erinia bay on Nea Kameni island

The Georgios crater

The crater lake Palea Kameni island
In the morning we embark on a chartered boat that will be at our disposal for all the day. From the little port of Amouthi or Apothikes (Akrotiri) we will sail to the youngest land of Greece: Nea Kameni, the still active volcano of Santorini. We will start early in the morning, avoiding the crowds and having the best light of the moon-like crater landscape. Hot gas-exhalations (so called "fumaroles") show that the magma chamber below the volcano is still active. Later, we will sail along the island to the other volcanic island Palea Kameni. Enjoying the spectacular cliffs of the caldera from the boat, we will return to Oia or Akrotiri in the afternoon.
Day 5: Sailing to Milos island & ancient Milos

The bear rocks (c) Tobias Schorr
Today is a very relaxed day, with the option to spend much of the day on a boat tour around Milos' legendary coastline: we sail around Milos' bizarre and fantastic coastlines,- likely to become an unforgettable excursion! Be sure to have plenty of film/storage media with you, since you might be using it ALL! A swimming break in particularly beautiful spots is included (weather and sea conditions allowing).
Highlights include Cape Vani with its impressive lava intrusions, old pillow lavas, sea caves, the white famous "Kleftiko" cliffs, made of imposing white pumice layers where in former times, fishermen and pirates used to hide within the bizarre coastal area.
We pass the cross-section of a large volcanic pumice cone (Tsigrado) and multi-colored cliffs of hydrothermally altered volcanic rocks on Milos' southern and eastern coasts. Another highlight are the Glaronissi islands, where we can marvel at their spectacular columnar-jointed lavas, and the white pumice cliffs of Sarakiniko.
The boat tour normally costs between 80-100 EUR per person.
The evening is free (dinner not included).

Les ponces de l'éruption Minoenne

Chèvre sur Palea Kameni

Le groupe avec des amis
"Bonjour de France, enfin du soleil ici pas le même que celui de Santorin bien sûr, mais c'est toujours agréable.
Le retour en France a été difficile après avoir vécu une semaine hors du commun dans un décor extraordinaire. Je remercie Tobias et toi pour votre façon de partager votre passion et de nous faire entrer dans cet univers décalé avec la vie "normale" de tous les jours.
J'ai apprécié la découverte géologique de l'île, l'initiation à la compréhension de la formation de l'île et des volcans, les rencontres avec des gens simples mais de caractère de Santorin.
Le temps s'est arrêté pendant une semaine et je garde des souvenirs d'odeurs, de couleurs, de plats partagés avec le groupe.j'ai revu les photos prises pendant le voyage, les couleurs et les paysages étaient tellement extraordinaires que les résultats sont surprenants même avec mon simple appareil photo. J'aimerais envoyer les photos de groupe prises dans la taverne de nicolas à "yurgos", peux-tu m'envoyer leur adresse?Egalement j'aimerais commander le livre de Walter Friedrich, mais je n'ai pas noté l'éditeur.Merci pour ces renseignements.
Bonne continuation dans tes voyages
ps: quelques photos jointes... Myriam" (Myriam T., Orléans)
Margrit from Potsdam about the Faszination Volcano tour on Santorini (Oct 09)
"Hallo Tom,
wieder einmal war es sehr schön auf Santorin und ich möchte mich für alles bedanken. Die Organisation, unser Hotel und die vielen neuen Eindrücke, welche du uns vermittelt hast sind kaum in Worte zu fassen. Vor allem aber danke, dass ich noch so kurzfristig teilnehmen konnte.
Eure Touren sind schon etwas Besonderes und mit viel Esprit, sehr persönlichen Einsatz, so dass man sich sofort wohlfühlt und immer gern wiederkommt.
Herzliche Grüße, Margrit" (Margrit from Potsdam, Faszination Volcano tour)
Gudrun from Dresden about the "Fascination Volcano" Tour in October 2009
"Hallo Tom,
nochmals vielen herzlichen Dank an Dich und die anderen für die schöne gemeinsame Woche mit dem gelungenen Mix aus Natur und Kultur, Sonne, buntem Stein und blauem Meer, Wandern und Neues Lernen, ein bisschen Anstrengung und Genuss!
... Weiterhin viel Glück bei allen Euren Unternehmungen und herzliche Grüße - Gudrun"
Sandra from California about the "Fascination Volcano" tour on Santorini:
"...Somehow I missed Tobias' link to photos and, fortunately, saw it through your note. Just finished looking at each image. Now, I"m exhausted! Stunning, and brings back keen memories, indeed. A whirling, dizzying journey to a version of Santorini unknown to most travelers. From moment we dropped luggage at Aktori to wine-tasting, to walk between villages, to our magical boat trips, to trek around caldera ledge, to climb up limestone mt., to smoking sulpher, to ancient city of Thira, to dreamy soups, best goat cheese, limpets and baklava...on and on. Tom and Tobias, our intrepid, ever-onward guides are a terrific team. Such compatibility among group of 17--wondrous again. How lucky was that??
Crazily, I just returned from 12 days in China...thus, a combo Greece/China 5-week adventure to savor and treasure. From yogurt, white villages & volcanoes to noodles, mountain temples & cave grottos. All intrigue and mystery and contrasts galore...
Best hugs,
Sandie"
Valerie's feedback from the trip on Santorini, May 2009
"Dear Tom & Tobias. Thank you for our remarkable trek in Santorini and Methana--for the beautiful memories and breathtaking photos.
... Coming home to Tobias' pictures gave me time to slow down and appreciate the remarkable experience we had.
I braved edges with Tom's help, jumped on boats with swirling seas (Daphne said I landed, elephant like, on poor Steve flattening him). ... The views took my breath away. ... Remember the oasis where we drank fresh squeezed orange juice and cake? I doubt whether juice will ever taste that good again. ... Little did I know that a bonus to our trip was the leader's desire for good food--and wine-- at the end of the day.
I have new appreciation for magma, volcanic bombs, the beauty of the caldera, smoking sulphur, adjectives that describe volcanic formations and olive trees found preserved in volcanic ash.
Thank you Tom and Tobias for a remarkable experience, and for your good choice in participants. It was a great group. Valerie" (Fascination Volcano, Santorini tour)
"... This was one of those wonderful adventures that we loved at the time, but loved even more as we looked back at all of the places we'd been, the lovely people we met, the great bond we developed. And......a birthday - high atop a volcano - that I will remember forever!
...Many hugs, Daphne" (D. Lewis, Washington, Santorini tour)
"Hi Tom,
This trip had everything! It was so much better than the standard tourist trip to Santorini (we felt so superior the folks who arrived on the 10 story floating skyscrapers and who apparently devoted their time on the island to shopping!). The hikes were good exercise, but with your encouragement to the less athletic among us, not too tough. We got to see so many parts of the island that most visitors don't get to see. And our reward for energetic hiking was delicious food, and lots of it. I appreciated that we got to eat a whole variety of local foods and wines which do not appear on the conventional menus of Greek restaurants in the U.S. I ate like a champ but didn't gain any weight!
I particularly appreciated the interpretation of the geology that you provided. On the way to the airport, you asked what was my favorite thing we did. I liked all the hikes, and especially the accomplishment of doing so much in a short time, but the big thrill, I think, was visiting the small geology museum in Perissa and seeing the critically significant preserved olive tree that you discovered and having you tell us about the find. Thanks for a really wonderful experience!" (Linda K, Olympia (WS), Santorini May 09)
"Hallo, Tom Zuerst vielen Dank für die tollen Photos, ich zeigte sie auch Helene und wir schwelgten wieder in Erinnerungen an unsere gemeinsamen Ferien. Es war eine wirkliche lehrreiche und zur gleichen Zeit auch sportliche Reise gewesen. Vor allem wurden auch unsere grauen Zellen aktiviert........
Auch über die Organisation muss ich Dir noch nachträglich ein grosses Lob aussprechen!!!!!
Irgendwann werde ich wieder eine Reise mit Deiner Organisation durchführen. Ich habe ja Einiges lesen können ( sites internet). Ich wünsche Dir eine schöne Adventszeit sowie natürlich auch vielleicht ruhige Weihnachten und einen tollen Rutsch ins Jahr 2009, sowie weiterhin viel Erfolg auf Deinen Reisen.
Und vielleicht irgendwann einmal wieder ?! Alles Liebe und Gute Uta" (

"Bonsoir Tom,
Merci pour les photos de Santorin qui sont magnifiques! Et encore
félicitations pour l'organisation de ce voyage. Quand on revoit les photos et le film qu'a fait Yvon, on se rend compte qu'on a non seulement
bien vu l'aspect Géologie de cette île, mais aussi l'aspect humain... Bonne continuation (les Suisses disent "bonne suite")
und alles gute. Nathalie et Yvon" (

Pirgos village on (Greek Easter) Good Friday (21 April 2006)
"Hi Tom, Now that we are back home, I wanted to thank you for your patience in showing us so many different aspects of Santorini: the history of volcanic eruptions and geology, local wine and food, Easter pageants, great walks and views, ancient excavations, etc. We enjoyed our stay very much! ... please give our regards to Koula and her family. We really appreciated that they invited us to share their fabulous Easter meal with them. It was very kind of Tobias to meet us for an evening on such short notice. ... Viele herzliche Gruesse Ursula and Bill" (May 2006, Ursula & Bill from Canada)

"Hi Tom, just a note to thank you for a great tour in October, it was great fun and I learned much, the food and company were excellent, the whole experience was fantastic. I see I even made it to the picture gallery! I have been busy with the thin sections, and have attached a few photos for you to look at. As is often the case ones that you expect to be good are disappointing, e.g. Cape Riva Ignimbrite, while Dacite, which looks to be just glass, shows a lot of structure, flow aligned crystals and good zoned feldspar and pyroxene. The sale of slides seems to be going well and I have stared a ‘shop’ on ebay http://stores.ebay.co.uk/Geosec-Slides which is difficult to keep stocked as they sell so quickly. The fund for future collecting expeditions is growing nicely! ... Once again thanks for October, send my regards to your Mother, and have a happy Christmas. Rob" (UK, Dec. 2005)

"Hi Tom, Hi Tobias, Just a very brief message to say "hello" and to thank
you for making my first encounter with Greece such a special one.
I have many fond recollections and stories to last a lifetime. ... I am slowly adjusting to life back in the states, but missing my traveling companions very much. Please send my best regards to Regina and remember too that you will always have a place to stay should you come to San Francisco. With warm regards. Karen" (San Francisco, Oct. 2005)

"Hi Tom, Thanks again for the super week on Santorini! It really was the experience I expected and I would heartily recommend your trip to anyone interested in combining a holiday on the Greek islands with geologically fascinating day walks. Well done!" (Bob Davenport, Germany)
"…I am so pleased to tell you about Tom's Santorini tours! My preference for travel is to be "as close to the ground" as possible. By that I mean I avoid tourist areas and really look for unusual or cultural/educational experiences.
Tom's tours are both intimate and professional. Tom is an expert in not only volcanic activity past and present, but he is also an expert on Greek life and culture. He knows the people, and they love him. Because Tom has lived in Greece for several months of the year for several years, he is well known and appreciated by the locals. This appreciation for Tom and the people he brings on his tours is rewarded by the community with absolute joy in service. For example, the last night of the tour we had a meal at a taverna on a beach. The restaurant gave us each a choice of anything on the menu. We were treated to amazing traditional Greek food, from small fish to hardbread, feta and olives, and amazing desserts. All of this was served in casual fashion on a makeshift outdoor patio almost in the sea! (not quite)
My favourite day was the trip to the volcano. We boarded a small boat and were transported to the volcano by the most humerous and typically Greek character, Sostas. Sostas is a friend of Tom's and can be seen on the Discovery show featuring Tom and Sostas and this tour. We landed on the volcano and Tom explained its history and answered any questions we had. We then swam in the volcanic waters at Sostas's house as Sostas prepared a traditional fish soup, hardbread, feta made from the goats that wander around the hills surrounding Sosta's property, olives, ect. An absolutely marvelous day. I must point out local tours to the volcano generally involve large boats with hoards of tourists who are dropped off and picked up with no explanation of the volcanic activity or history. Tom ensures a personal and educational cultural experience." (Shelly Logan, Canada)

"Hello Tom, I send our last Bulletin because there is one article on the excursion Santorini. I profit to thank you again very much for the way you lead this tour all the people were very happy." (Pierre Vetsch, Société Vulcanologique de Genève, SVG) - the report (in French) is found in the Bulletin Nr. 45 of the SVG.
Extract of the bulletin report mentioned above, referring to the Oct. 2004 tour: "...L’histoire de Calliste (le très beau nom donné à cette île par les anciens Grecs) est extraordinairement bien inscrite sur les flancs de sa caldeira (plutôt des restes de ses caldeiras successives). Des évidences ont été trouvées pour au moins 4 caldeiras, suite à autant d’éruptions explosives. La dernière, la Minoenne, date de 1645 BC. Elle est gravée dans la mémoire de l’humanité... tellement elle est récente ! C’est tout cela, et bien d’autres choses encore, que nous sommes allés admirer (et tenté de comprendre) au cours de ce voyage.
Le magicien dans cette affaire, c’est Tom Pfeiffer, géologue-volcanologue mandaté par notre président pour nous accompagner. Tom a parfaitement répondu à notre attente. Passionné, attentif, pédagogue, à l’humour taquin, volontiers francophone, il nous a fait découvrir les secrets de cette île en sept jours bien remplis. Je parlerai plus loin de son parcours professionnel..." (Jean-Maurice Seigne, Genève, Switzerland)
