Mt Ijen Experience
This Mt Ijen Hiking adventure was a continuation of our journey after Mt Bromo Hiking. From Bromo, we traveled by van to Banyuwangi, a trip that took around 6–7 hours. Upon arrival, we checked in at Ijen Hotel Blue Fire, where we rested and prepared our gear.
At around 12:30 AM, we woke up and began preparing for one of the most anticipated parts of our East Java adventure—Mt Ijen Hiking. By 1:00 AM, we had already left the hotel, traveling through quiet roads as we made our way toward the mountain. Before reaching the trail, we stopped at a local clinic for a mandatory health check, which is required due to possible sulfur exposure during the Kawah Ijen hike. Once cleared, we continued the drive feeling both excited and slightly nervous about what lay ahead of our Mt Ijen trekking experience.
The trip from the clinic to Paltuding Basecamp took only around 30 minutes. Upon arrival, we organized our gear, adjusted our layers for the cold night air, and made sure our gas masks were ready—an essential item for the Mt Ijen Crater Hike. After a brief moment to gather ourselves, we officially started the hike at around 2:30 AM, joining the steady stream of headlamps that marked the beginning of our Mt Ijen blue fire hike.
The path was well-established and relatively manageable, with a gradual incline that makes Mt Ijen Hiking suitable even for beginners with decent fitness. The steady pace allowed us to conserve energy, while the cool mountain air made the climb more comfortable. Along the way, we noticed locals offering a cart service, similar to a wheelbarrow, for hikers who preferred not to walk uphill—an option sometimes seen along the Kawah Ijen hike route for those needing assistance.
After roughly two hours of trekking, we reached the crater rim at around 4:30 AM. By this time, the area was already crowded, with hikers carefully navigating a narrow and congested entrance near the crater. Patience was key as people queued to descend, and extra caution was needed due to limited space and low visibility during this Mt Ijen trekking experience.
Despite the darkness, the descent was manageable and well-guided. Within minutes, we reached the viewing area where the iconic blue fire of the Mt Ijen blue fire hike could be seen glowing against the night sky. The electric-blue flames were surreal, flickering from sulfur vents and creating an otherworldly atmosphere unique to Mt Ijen Hiking. Although getting closer was limited due to crowd control and safety restrictions, we still managed to capture photos and videos from a safe distance.
As the night slowly gave way to dawn, the sky began to brighten, revealing the dramatic landscape surrounding us. The most unforgettable moment came when the turquoise crater lake finally came into view, glowing softly as the sunlight reached the crater. Seeing the lake in full light was a striking contrast to the darkness of the blue fire experience and easily became one of the highlights of our Mt Ijen Hiking journey.
After spending time soaking in the views and capturing more photos, we began our ascent back to the crater rim. This climb was the most physically demanding part of Mt Ijen Hiking, as the trail required a steady uphill push after several hours of activity. Once we reached the top, however, the trail gradually eased into a gentle descent, making the walk back far more comfortable.
By around 8:00 AM, we arrived back at Paltuding Basecamp, feeling tired but deeply satisfied. After freshening up and taking a short break, we boarded the van and began our journey back to Bali, officially closing our Mt Ijen Hiking adventure. From the midnight ascent to the breathtaking crater views, the experience was a perfect finale to our exploration of East Java’s iconic volcanic landscapes.
