Indonesia… Just the sound of this word is enough to excite every geologist’s fantasy!! And that’s the place where we are right now!
Here the geology is something living, not just strange and boring words on a book: Indonesia is the hot and restless daughter of the convergence between the Indo-Pacific and Australian plates, animated by earthquakes, tsunamis, giant slides and….volcanoes, of course!!
We are now in Bandung, 140 km east of Jakarta, close to the Tangkuban Perahu Volcano (the “overturned boat-shaped” volcano), so we have enjoyed a “wet” tour in the lush rainforest which covers the flanks of the mountain, reaching a small crater with steam and boiling water springs. There you can even cook an egg and eat it in the foggy atmosphere created by the hot steams and the showery rains.
But the best is yet to come… through a slippery and narrow “natural staircase” we eventually reach the top of the volcano and have a look inside the main crater. And there you do feel that the mountain is alive, blowing its white fumes and quietly sleeping before the next eruption…Towards the east endless and mysterious mountains form the backbone of Java, while thousands meters below your feet the Australian plate is being pushed northwards and downwards in the mantle. The emotion is too strong (and the humidity too!), so we have to go away and eat something.

We go down to Lembang, stopping at a typical Indonesian restaurant, where you can eat the famous ayam goreng (fried chicken). This is the real “Indonesian experience”, eating strange and spicy things and drinking hot tea and mango juice while the rain is hitting the roof.

The best conclusion for such a nice day would be a crazy ride on a rollercoaster-like road, packed up in a small van that will carry us to the hotel and the desired hot shower.
