Discovering the Volcanic Wonders of the Aegean Lava, craters and untamed beauty

Discovering the Volcanic Wonders of the Aegean Lava, craters and untamed beauty

Embark on a remarkable journey through the dramatic landscapes created by the volcanic activity of the past in the Aegean. The South Aegean Volcanic Arc is one of the most famous in the world and was created by the subduction of the African lithospheric plate beneath the Eurasian one. Enjoy the warm thermal waters of Methana, explore the enchanting caldera of Santorini, walk around the impressive craters of Nisyros. This route blends natural beauty, history and culture and can be divided into shorter segments, depending on the time available.

    Methana: Rewarding hikes and thermal baths

    Methana: Rewarding hikes and thermal baths

    Renowned since antiquity for its thermal springs and volcanic activity, Methana is one of the most historic spa towns in Greece. According to one theory, Methana owes its name to methane gas, released during volcanic eruptions. Entering the settlement, admire the monumental building of the old bathing facilities of Methana, designed by the famous architect Ernst Ziller. Nearby, at the entrance to the spa town, sulfurous waters flow into the sea, with their characteristic milky hue and pungent smell, which you will quickly get used to. Go down the stairs, take a dip and enjoy their beneficial properties. The locals have incorporated the thermal baths into their daily routines in winter and in summer! Further north along the shoreline, make a stop at the chlorinated baths of Loutra Agiou Nikolaou (Baths of Agios Nikolaos) and then continue to reach Loutra Pausania (Baths of Pausanias) for an unprecedented natural spa experience right beside the sea.  Before leaving Methana, don’t miss the chance to hike the volcano. The entire peninsula once emerged from the sea, after successive volcanic eruptions, which shaped the complex terrain you see today. Part of the South Aegean Volcanic Arc, the volcano of Methana experienced intense activity from 276 BC to 239 BC. A network of trails of varying difficulty stretches across the peninsula. Experienced hikers can set off from the port and move to the summit of the volcano of Kameni Chora, a beautiful route lasting 5-5.5 hours. Alternatively, for a shorter yet equally memorable experience, start at the volcano and, following a downhill course, walk to Loutra Pausania. Combine hiking with a hot thermal bath and conclude your exploration of Methana in the most ideal way.

    Santorini: Sunset overlooking the caldera

    Santorini: Sunset overlooking the caldera

    Stand in awe before one of the most breathtaking volcanic landscapes in the world. The caldera of Santorini, the huge underwater crater formed by the eruption of its volcano at the end of the 17th century BC, when three quarters of the island sank beneath the sea, offers a spellbinding travel experience, worth living at least once in your life. Board one of the boats departing from the bay of Fira, the port of Athinios, Ammoudi (Oia) or Vlychada and enjoy a mesmerizing cruise to the impressive caldera and its small volcanic islets. Wear comfortable closed shoes and cross the lunar landscape of Nea Kameni reaching crater Georgios, where you will see hot gases emitted from its active fumaroles (openings in the ground that release hot volcanic gases). Then, enjoy a dip in Palaia Kameni, in the thermal waters of the hot springs where sulfur rises! Conclude your day on Thirasia Island, just opposite Oia, with the whitewashed Cycladic houses and the incredible views of the caldera. After strolling through Manolas (Chora), swim in the black beach of Agia Irini (Riva) and then explore Potamos, the traditional settlement of the island with the beautiful cave houses.  In Akrotiri you will travel back in time. This prehistoric city, which was one of the most important urban centres and ports of the archipelago in the Bronze Age, was buried beneath volcano ash during the eruption of the volcano in the last quarter of the 17th century BC. The volcanic ash covered the streets, the houses, the exquisite frescoes, the objects, preserving everything intact. At the archaeological site, there is a bioclimatic shelter, which ensures pleasant visiting conditions even during the height of summer.  An "extension" of the archaeological site is the Museum of Prehistoric Thera in Fira one of the most important museums in the country. A variety of exhibits in excellent condition, from the famous frescoes of Akrotiri to household items, Linear A signs, tools, etc., reveal the everyday life of the people of the time. Through its modern museological narrative, you will feel as if you are wandering around the prehistoric settlement just before its final abandonment due to the eruption of the volcano. The volcanic activity is also evident on the colourful and mysterious beaches of the island. Near the archaeological site of Akrotiri, seek out Kokkini Paralia (Red Beach), where the red of the rocks meets the blue of the Aegean in an impressive palette of colours. On Mavri Paralia (Black Beach), one of the most photographed in the Aegean, you will enjoy the sun lying on the exotic jet-black sand, swim in crystal clear waters and raise your adrenaline by doing water sports in the most evocative landscape. Perissa, Perivolos and Agios Georgios form a continuous five-kilometer stretch of coastline, inviting you to find your perfect spot. The architecture of the settlements of Santorini was adapted to the volcanic origin and morphology of the soil. Sometimes they unfold linearly, on the rim of the caldera, such as Oia, Fira and Imerovigli, sometimes they develop around a fortified core, such as Pyrgos and Emporio. Elsewhere they develop underground, such as Vothonas, Foinikia and Karterado, with houses carved into the volcanic Theran land.  Each village has its own unique story to tell, yet all routes ultimately lead to Oia and its mythical sunset. Be sure to be there at sunset, when nature paints the horizon with the most intoxicating colours and the sun dives into the sea, behind the volcanic islets of Palea and Nea Kameni. Experience the breathtaking spectacle that unfolds before your eyes: this is the most beautiful sunset in the world.

    Nisyros: A living page of geological history

    Nisyros: A living page of geological history

    A world-class attraction is the volcano of Nisyros that boasts a remarkably well-preserved caldera. Its oldest rocks are no more than 150,000 years of age. Along with the surrounding islets (Pergousa, Pachia, Kandelioussa, Stroggyli, which, like Nisyros, belong to the Natura 2000 network as a Special Protection Area for Birds) as well as the wider marine area, it has been selected to be included in the UNESCO Global Geoparks Network*.  The island is home to 450 recorded species of flora, making it the only "green" active volcano in the Aegean. Nisyros is a stratovolcano, composed entirely of volcanic rocks, formed by successive explosive and effusive eruptions. Many fascinating facts about the South Aegean Volcanic Arc and the volcano of Nisyros itself can be uncovered with the help of rich audiovisual material at the Volcanological Museum of Nisyros in Nikia. And then, experience the volcano! Walk carefully through crater "Stefanos", one of the largest phreatic craters in the world, measuring 260 x 350 metres and a maximum depth of 27 metres. Then, admire the other craters of the island: the small in size "Andreas", the elliptical shaped "Big Polyvotis" and the youngest "Small Polyvotis", whose floor measures 30 metres in diameter.  Discover the 24 distinct geosites of the Geopark and hike through the ten specially designed geotrails that will uniquely introduce you to the untouched volcanic terrain of the island.  Explore the settlement of Emporios with the two-storey Nisyrian houses, perched on the rim of the caldera. Spend relaxed afternoons in the village of Nikia and take a seat in the magnificent square (Porta) with its pebble pavement of unparalleled art. Reach the chapel of Prophet Elias for panoramic views of the craters and the village. In spring, enjoy a real botanical paradise with wild orchids, lavender, the endemic Nisyros bellflower and hundreds more species of flowers. In the summer, witness the entire island transform into a cultural stage during the Nisyros Geopark Festival which uniquely connects the natural landscape with art.
