Greece

Geotours, geologic walking and study tours to the active volcanic areas of Greece


Discover what is behind one of the oldest legends of the ancient world, the legend of Lost Atlantis, probably connected to the huge volcanic explosion on Santorini in 1613 BC, and get an insight, from first-hand knowledge, into the natural history of one of the world's most violent volcanoes. Discover the deeply intertwined natural and cultural history of Greece's active volcanoes and let yourself be amazed by their variety and beauty. Greece is the best open textbook for geology and nature lovers! Combine it with the unique ambiance and the relaxed lifestyle only Greece can offer. We specialize in small group tours on scheduled dates a few times in spring and/or autumn, as well as private geology-focus tours to Santorini, Milos, Nisyros, and the Saronic Gulf, ideal for a short 2 or 3-day trip starting in Athens. Our tours are accompanied by a professional geologist with first-hand research experience in Greece as well as fluent in Greek, English, and German (usually volcanologist Dr. Tom Pfeiffer who lives in Athens most of the year).
