Ijen, located at the eastern end of Java, is now one of the island's best known and most visited volcanoes, along with Mount Bromo.
Its acidic lake and impressive sulphur bearers attract its share of curious hikers every year. A successful trip to Indonesia cannot do without a volcano climb, and this region of Southeast Asia offers a wide range of treks, depending on the physical condition of each person.
Ijen is located in the southeast of the Kendeng caldera. This caldera, which was formed about 50,000 years ago, is the result of the explosive eruption that destroyed Old Ijen, the ancient volcano that peaked at 3500 metres.
With the first rays of the sun and the dawn, the turquoise waters of the lake light up gently before our eyes. But beware of those who want to take a dip, as this is the most acidic lake in the world.
To go back up to the ridge, you sometimes have to climb the somewhat steep wall of the crater, so vigilance is required.
Once up there, you can watch the sunrise and enjoy the exceptional panorama. On a clear day, before the morning mist has invaded the horizon, we can see the majestic Mount Raung, which rises to more than 3300 metres, towards the south-west. Behind us towards the east, we can see the highest point of the Kendeng caldera, Mount Merapi, not to be confused with its namesake located near the Buddhist temple of Borobudur. This is an opportunity to take some nice pictures before heading back down to the base camp.
The descent is not dangerous in itself, but be careful with your knees and joints, which are put to the test!
Climbing Kawah Ijen and descending into the soufriere at the edge of the acid lake is a unique experience. From the blue flame flows that snake through the night to the hard-working men, Kawah Ijen grips you and leaves you speechless...
To visit Ijen, you will need to make sure you take gas masks to protect yourself from inhaling the toxic gases escaping from the volcano.
These masks will normally be provided by the guides who accompany you.
Also, swimming is not allowed: remember that this is the most acidic lake in the world.
There is no accommodation around Ijen.
It is therefore advisable to stay in the town of Banyuwangi which is one of the closest to the volcano.
