Ijen Plateau or Ijen Crater is Located on the eastern of Java, Plantations have been long been established on the plateau’s rich volcanic soil which also supports a diverse ecosystem of lush forests and abundant flora.
One of the main attractions of the area dazzling turquoise blue lake and blue fire of Ijen Crater (Kawah Ijen), where local laborers mine the valuable sulfur deposits from the water’s edge and carry mineral-laden baskets weighing up to 80kg.Ijen Crater (indonesia: Kawah Ijen) volcano (2386m) is an active strato volcano located on the eastern part of Java Island. The top of Ijen volcano is characterized by a very acidic crater lake containing 27.5 million m³ of turquoise-colored water. This lake is the biggest reservoir of hot and acidic water on world.
Ijen Plateau near Banyuwangi and Bondowoso is a less well known but in its own way equally spectacular area of volcanic activity. Ijen Plateau is the centre point of the large mountain range west of Banyuwangi and which abutts the Baluran National Park to the north. For the adventurous traveler a visit to the Ijen Crater (Kawah Ijen) is a must whilst in the region. The crater can be approached from Bondowoso in the west or Banyuwangi in the east. The route of Bondowoso is recommended as the road is relatively better (although that is not saying much) and the 90 min foot climb much easier. When you arrive the colour of the water in the lake is scarcely believable being an extraordinary vivid aqua blue. Evidence of volcanic activity is everywhere with steaming water and brilliant yellow crystalline sulfur deposits. The Ijen Crater is one of the great natural wonders of Indonesia. If you arrive at Ijen before sunrise, you can see the Blue Fire which is a phenomenon due to the self ignition of the sulfur produced by the volcano.
