Ijen Crater, East Java : Volcano, Acid Lake and Blue Flames

Ijen Crater, or known to Indonesians as Kawah Ijen, is one of the top recommended volcano in Indonesia to be visited. This active crater of 134 sq km has a landscape of volcanic cones of both Mount Ijen and Mount Merapi (not to be confused with the famous Mount Merapi in Central Java).
This group of stratovolcanoes lies in East Java. Inside the crater you will see a magnificent turquoise sulphur lake that exudes flames, blue fire at night and smoky white in the day.
Here you will also find many sulphur collectors that hike up here to mine the minerals of Kawah Ijen but this had been highlighted badly recently in the media due to the fumes being harmful to human and its extremely harsh working conditions. 

Where is it

Ijen Crater lies nearby Banyuwangi and Bondowoso. Ijen plateau stood as the centrepoint of the large mountain range west of Banyuwangi and as part of Baluran National Park to the north.

Why go

Come to Ijen Crater for the largest acidic lake in the world and for the mesmerizing blue flames in the night. Besides it is one of the best volcanic mountain of Indonesia with this one brimming with the rare sulphurs. 

When is the best time to go

June – August where there is less rain but more tourist
But that being said, Indonesia being a fairly mild weather of just rain and shine, most of the time is a good to go to Ijen Crater, just check for local weather as you head there.
Also try to avoid weekends if you do not want the crowd.

What to see

World’s largest acidic lake, which is in the brilliant turquoise color that captures not only the sunlight but every traveler’s heart.
Catch the miners hard at work, carrying heavy laden basket of sulphur though you may be disturbed by it and feel sorry for them. Note in mind that the sulphur fumes are poisonous and these miners are subjected to it daily for long hard-laboured hours.
There are coffee plantations cover the Ijen caldera floor where many travelers head there to visit the waterfalls, hot springs or just enjoy the dramatic volcanic scenery.

What to do

Hiking up to Ijen Crater at night
There are few options for visiting Ijen crater, you can either start at 2am or 4am to arrive at the top of the crater by daylight. Many travelers recommend to do the night hiking up to Ijen Crater to catch the magical blue flames or also known as blue fire. To get this you have to arrive at the top before sunrise of 6am. The hike up takes 1.5-2 hours averagely and can be quite steep The good thing is at this time there are not many other tourists around as well. After being mesmerized by the blue flames enough, you can sit back at the summit and wait for sunrise which offers another spectacular view.
Walk around the Ijen crater rim
You can take a walk around the rim of Ijen crater or approach the lake which will take about 40 minutes walk.

Ijen volcano

Ijen volcano in East Java contains the world's largest acidic volcanic crater lake, called Kawah Ijen, famous for its turquoise color. The active crater measuring 950x600 m is known for its rich sulphur deposits which are being quarried.
The volcano is one of several active stratovolcanoes constructed over the 20 km wide Ijen caldera, the largest caldera in Java.
Eruptions from Ijen are very hazardous because of the risk of the lake draining to form catastrophic lahars. 

The Ijen volcano complex at the eastern end of Java consists of a group of small stratovolcanoes constructed within the large 20-km-wide Ijen (Kendeng) caldera. The north caldera wall forms a prominent arcuate ridge, but elsewhere the caldera rim is buried by post-caldera volcanoes, including Gunung Merapi stratovolcano, which forms the 2799 m high point of the Ijen complex. Immediately west of Gunung Merapi is the renowned historically active Kawah Ijen volcano, which contains a nearly 1-km-wide, turquoise-colored, acid crater lake. Picturesque Kawah Ijen is the world's largest highly acidic lake and is the site of a labor-intensive sulfur mining operation in which sulfur-laden baskets are hand-carried from the crater floor. Many other post-caldera cones and craters are located within the caldera or along its rim. The largest concentration of post-caldera cones forms an E-W-trending zone across the southern side of the caldera. Coffee plantations cover much of the Ijen caldera floor, and tourists are drawn to its waterfalls, hot springs, and dramatic volcanic scenery.
