Mount Ijen is located between the border of Banyuwangi and
Bondowoso, East Java, Indonesia. The location is side by side with Merapi Mountain.
The height of Mount Ijen is 2,443 meters, still lower when compared with Mount
Bromo or Semeru so trekking to the top of Ijen is also easier. Mount Ijen is
famous for its unparalleled crater beauty.
Ijen crater is the largest acid water lake in the world.
Your tiredness from climbing will pay off with the beautiful blue Ijen Crater.
Moreover if you decide to camp here, at 02.00 to 04.00 in the morning you can
see the blue fire phenomenon that you will not find in other mountains, even in
other countries, because supposedly blue fire in Mount Ijen is the only one in
world.
