Volcanic immersion in Java, between hiking and culture

An early departure takes you to Carita , on the west coast of Java. En route, you'll visit the Cikoneng Lighthouse , built in 1885, a testament to the island's maritime history. The journey continues to the Pasauran Volcanological Observatory to discover how Krakatoa 's activity is monitored daily. An enlightening immersion into the heart of the island's geological forces.

In the mid-morning, you'll board a speedboat to the Krakatoa archipelago. You'll approach Anak Krakatau volcano by sea, formed by the famous eruption of 1883 and still experiencing unstable activity since 2018. Depending on the current volcanic conditions, you'll sail around the island at a safe distance. If the situation allows, a partial ascent of the flanks of the old cone is planned to observe the new crater formed in 2021 , which still frequently erupts. Return to Carita in the afternoon, after this striking encounter with one of the most iconic volcanoes on the planet.

An early departure takes you to Bandung , nestled at an altitude of 768 meters and nicknamed "The Paris of Java" for its colonial heritage and vibrant cultural atmosphere. The city is surrounded by volcanoes, including Tangkubanperahu (2,076 meters), located to the north. You'll gain some altitude to explore its ridges and smoking slopes , evidence of intense geothermal activity. An easy walk allows you to observe the local vegetation, including endemic tree species . In the afternoon, you'll visit the Bandung Geological Museum , managed by the Indonesian Volcanological Center, to gain a deeper understanding of the dynamics of the archipelago's volcanoes.

You'll cross Java's volcanic chain to reach the vicinity of Mount Papandayan . Along the way, the first fumaroles will appear: those of the Kamojang crater , which you'll reach on foot during a guided hike . There, you'll discover a unique landscape: bubbling mud pools , steam vents , and sulfur deposits create an almost surreal scene. The visit continues at the Kamojang geothermal center , located in the heart of a vast caldera , where the harnessing of volcanic energy takes on its full meaning. Transfer to your accommodation at the end of the day.

An early departure takes you to Mount Galunggung , whose vast crater is revealed during a hike along its slopes . After this exploration, you descend to observe the still-visible scars of the 1982 eruption . On that day, a devastating lahar —a mixture of mud, ash, and volcanic debris—rushed down the volcano's slopes, leading to the evacuation of more than 30,000 people . In the afternoon, you travel to Baturaden , at the foot of Mount Slamet , for a peaceful end to the day in this small spa town on the edge of the rainforest.

An early morning walk takes you through a mosaic of landscapes: Javanese villages , terraced rice paddies , rivers , and dense rainforest unfold along the trail. After this immersion in nature, relax in a natural setting of hot springs , perfect for rest. A reflexology massage using sulfurous mud , given by a local therapist, completes this wellness interlude. In the afternoon, you travel to Wonosobo , the starting point for the Dieng Plateau.

An early departure takes you to the volcanic plateau of Dieng , a densely populated and intensively cultivated region. There, you'll discover a high-altitude geothermal area , marked by fumaroles, colorful fields, and the presence of ruined Hindu temples , vestiges of the 8th century. After this brief exploration, the route continues to the Buddhist sanctuary of Borobudur , a UNESCO World Heritage Site, built between the 8th and 9th centuries under the Sailendra dynasty. You'll then arrive in Yogyakarta in the early evening.

A day dedicated to discovering Yogyakarta , considered the cultural capital of Java . The cradle of traditional arts, the city retains a strong identity, embodied by its kraton (still-inhabited royal palace), its batik artisans, its shadow puppet shows, and its bustling markets. The atmosphere is both intellectual and popular , marked by a vibrant spiritual heritage. This urban stop offers an immersion into everyday Javanese life , a blend of history, creativity, and modernity .

This day is dedicated to studying the impacts of the 2010 eruption of Mount Merapi . From a viewpoint at 1,200 meters altitude on the volcano's eastern flank, you will observe the traces left by this major event, marked by a succession of extreme phenomena . You will continue your analysis along the Gendol River, the path taken by pyroclastic flows that reached several villages. The current geological dynamics , still very active, will then be explored at the Merapi Museum . In the afternoon, you will visit a refugee center established after the eruption, before concluding with a visit to the Hindu temple of Prambanan , an architectural masterpiece and UNESCO World Heritage Site.

An early departure takes you towards Malang via the highway, before you travel by 4x4 to the Tengger caldera via the southern route, passing through Tumpang . This vast volcanic amphitheater, with its lunar landscape, is home to Mount Bromo (2,329m), whose active fumaroles serve as a reminder that it remains at alert level 3. If conditions permit, you will climb to the summit in the afternoon for an immersive experience in the heart of this unique sea of ​​ash. You will then descend on foot to Cemorolawang , where you will be treated to a breathtaking view of Bromo and Semeru, two volcanic giants united in a single panorama.

In the middle of the night, you'll set off in a 4x4 across the sea of ​​sand , heading towards the summit of Mount Pananjakan (2,755m). At dawn, the sun reveals a breathtaking landscape : Bromo and Semeru , both active, release their plumes in the heart of a misty caldera. After this extraordinary moment, return for breakfast , then drive to Gunung Sawur , the Semeru observation post , which offers a better understanding of the activity of this dominant volcano. At the end of the day, transfer to the area around Banyuwangi , the gateway to Mount Ijen.

Early morning transfer to Paltuding , the starting point for the ascent to the crater of Mount Ijen . The climb leads you to an extraordinary volcanic landscape: a turquoise acidic lake , considered the largest in the world, lies at the bottom of a desolate crater . There, you'll observe sulfur miners at work in an open-pit mine , where gas-laden fumes color the air. After this striking experience, return on foot to Paltuding, then transfer to the port of Ketapang . You'll cross by ferry to Bali , before arriving at the peaceful resort of Pemuteran , on the northwest coast of the island.

A free day in Pemuteran , nestled between the sea and the mountains. For those who wish, it is possible to rent a boat (optional) to reach the reefs around Menjangan Island , renowned for their rich marine biodiversity . Tropical fish, multicolored corals, and crystal-clear waters create a truly preserved ecosystem , ideal for diving or snorkeling. It is also in this natural sanctuary that the rare Bali starling has found refuge, a symbol of the fragility of this unique wildlife.

Enjoy a free morning in Pemuteran , a chance to soak up the tranquility of the place one last time or stroll along the waterfront. Depending on your flight schedule, transfer to the airport for your return flight. End of services on site.
