Kawah Ijen is perhaps best known for its striking blue fire, a natural phenomenon that occurs as sulfuric gases combust upon contact with air, a spectacle that can best be observed at night. This blue glow, combined with the stark, rugged landscape of the crater, offers a breathtaking contrast to the serene beauty of the turquoise-colored acidic lake at the volcano’s center. The lake itself is one of the largest acidic lakes in the world, its water colored by the high concentration of sulfuric acid.

Getting to Kawah Ijen involves a journey through Indonesia’s lush landscapes. Visitors typically fly into Surabaya or Bali, and from there, travel by road to Banyuwangi or Bondowoso. The trek to the crater starts at the nearby village of Paltuding, which serves as the base for the ascent. The hike to the rim of the crater takes about 1 to 2 hours and is considered moderately challenging, requiring a good level of physical fitness. Trekkers are rewarded not only with the extraordinary sights within the crater but also with panoramic views of the surrounding volcanic landscape under the starlit sky.
