Santorini is not only a highlight when it comes to present a natural showcase of fantastic geology and volcanic history deeply interwoven with Europe's ancient history, but it is also a very photogenic island.

Spring in Greece is an explosion of colors, dominated by hundred shades of green and yellows. Meadows full of flowers, silver-green olive groves and the blue sea are everywhere. One area of particular beauty is the Saronic Gulf which also includes one of Europe's least known active volcanoes, the Methana lava dome complex. The photos presented were taken on 9 and 10 April 2019, following a tour to Methana & the Saronic Gulf. We also arrange private excursions to this highly interesting area, starting in Athens or other places nearby, for 2-4 persons and suggested length of 2-3 days. Please contact us if you are interested! (Photo: Tom Pfeiffer)

The hot springs at Polichnitos (Lesbos Island) are volcanic in origin. They range in temperature between 67°C and 92°C and are among the hottest natural springs in Europe. You can admire colorful rivers and ponds, or enjoy them in a small nearby traditional spa on location. The waters are enriched with natural radon, sodium chloride and are comparable to the Wiesbaden springs in Germany. (Photo: Tom Pfeiffer)

The Petrified Forest of Lesvos is one of the most fascinating and rare monuments of geological heritage in the world. Its creation, 20.000 000 year ago is connected with the intense volcanic activity in the Aegean during the Miocene period. In 1985, the forest was declared a Protected Natural Monument.

Milos is famous for its spectacular, multi-colored volcanic rocks, its beaches and a breathtaking coastal scenery. A boat tour around the island lets you best enjoy these marvels of nature. These photos were taken during a tour in April 2011. (Photo: Tom Pfeiffer)

Milos north coast has one of the geological wonders of the world to offer: the section around Sarakinikos Bay,- cliffs of ancient volcanic ash and pumice flow deposits, spectacularly polished and gullied by erosion. Normally, a sunbathers paradise in summer, it reveals a rough beauty when the wind and waves become stronger. The following are photos taken during a hike along the coast (something not to be missed when you travel to Milos!) in Oct. 2008. (Photo: Tom Pfeiffer)

Nisyros island is located in the eastern part of the Aegean Sea next to Turkey. Together with the isles of Kos and Yali, it represents one of the main active volcanic centra in Aegean Sea, along with Santorini and Milos. One of our VolcanoDiscovery tour guides, Ingrid Smet, made a short reconnaissance trip there at the end of September 2017. Judging from her photographs it seems another perfect destination for one of our Volcano Adventures as it offers all the classic ingredients of active volcanic phenomena, interesting culture, authentic traditions, excellent food, beautiful scenery, nice hiking and relaxing beaches!

Another excursion during the geologic walking tour is the 12 km hike from Fira to Oia, a classic walk considered one of the best and most scenic hikes in the world and one of particular geologic interest as well. It leads through the elegant streets of Fira, Firostefani, Imerovigli and Oia as well as old mule paths, and for most of the time offers breathtaking views over the northern caldera of Santorini, which was the site where the violent Minoan volcanic eruption around 1600 BC took place and reshaped the island forever. (Photo: Tom Pfeiffer)

On our second excursion during the geologic walking tour, we visit the most interesting sites along the southern caldera, an abandoned pumice quarry, as well as the excavated Minoan town near Akrotiri. The images here show the first part of a tour as on 30 April. (Photo: Tom Pfeiffer)
Santorini Island, Greece, spring 2019: Caldera hike (36 Images)
Normally, our first excursion during the geologic walking tour, we visit the area of the oldest volcanic rocks of Santorini found in the SW peninsula near Akrotiri and the lighthouse. It is a very varied walk along beaches, the caldera, through fields on old, mostly forgotten trails and mule tracks. Geologic highlights include spectacular submarine tuffs and lava domes, often with fantastic hydrothermal alterations. (Photo: Tom Pfeiffer)

The winter 2018-19 was particularly rainy in Greece. As a result, Santorini island was exceptionally green even at the end of April, when Tom guided our regular geologic walking tour on the island. Images taken on 27 and 28 April: (Photo: Tom Pfeiffer)

On one of the days during our geologic walking tours, depending on sea and weather conditions, we take the time to visit the historic volcanic islands of Nea and Palea Kameni in depth. The following shows some impressions from this excursion from 1 May 2019, and includes a dramatic weather display in the afternoon, caused by the arrival of moist warm air masses from Africa. Fortunately, this remained only a visual display and played out entirely high above in the atmosphere without affecting the ground. (Photo: Tom Pfeiffer)Santorini 2018-19 (16 Albums)
After a relatively rainy winter 2016/17, spring on the Greek islands was fantastic! Santorini, one of the most famous islands of the Cyclades, was no exception and offered a paradise for photographers: flowers and green everywhere, with the blue and white of the traditional houses and chapels. The following photos were taken during our Santorini photo tour in April 2017. Photo copyright: Tobias Schorr / Nature Discovery Tours. (Photo: Tobias Schorr)Santorini 2015-17 (1 Album)
The 1866-1870 eruption of Nea Kameni produced some of the most spectacular breadcrust bombs seen on any volcano. During a tour on Santorini, we visited the island in late Sep 2014 and looked at some of them: (Photo: Tom Pfeiffer)Santorini 2012-14 (4 Albums)

Methana opposite Athens in the Saronic Gulf of Greece is one of Europe's least known active volcanic areas. The peninsula consists of a group of overlapping prehistoric and one historic (around 238 BC) lava domes that overlie limestone basement. An underwater eruption occurred off the northern coast in around 1700 AD. Methana is known for its hot springs and uncrowded, beautiful green rural landscape. Team member photographer Tobias Schorr who has lived more than 10 years in Methana and knows the peninsula better than anyone recently spent countless hours documenting each of the more than 30 lava domes of Methana with his drone from the air. Here are the results: (Photo: Tobias Schorr)
