East Java, Indonesia — Indonesian authorities have closed the Mount Bromo tourist area as firefighters battle a growing wildfire inside Bromo Tengger Semeru National Park, one of the country’s most popular natural attractions.

The fire had burned approximately 176 hectares, or 435 acres, as of Sunday, according to authorities. The affected landscape includes dry grassland and other vegetation on and around the steep volcanic slopes. The park was closed to visitors on Saturday and is expected to remain closed until officials determine that conditions are safe.

Difficult Terrain Complicates Firefighting

Hundreds of firefighters, park rangers, police officers, military personnel, disaster-response workers and volunteers have been mobilized.

Authorities have deployed helicopters for water-bombing operations, while drones are being used to identify hotspots and monitor the movement of the fire. Ground crews are also creating firebreaks to prevent flames from spreading into additional sections of the protected area.

Officials said firefighting efforts have been complicated by steep slopes that make some hotspots difficult to reach. Strong winds and extremely dry vegetation have also allowed the fire to spread quickly.

The cause of the blaze had not been determined as of Sunday.

Dry Season Raises Wildfire Danger

Indonesia’s Meteorological, Climatological and Geophysical Agency has warned that the country’s dry season is expected to peak between July and September 2026.

Earlier-than-normal dry conditions, reduced rainfall and strengthening El Niño conditions have increased the risk of forest and land fires in several regions. Indonesia’s meteorological agency, BMKG

Wildfires have also been reported in parts of Sumatra and Borneo, raising concerns about damage to ecosystems, public health and regional haze.

One of Indonesia’s Best-Known Destinations

Mount Bromo is an active volcano in East Java known for its dramatic sunrise views, volcanic sand plain and cultural importance to the Tengger people.

The surrounding national park attracts domestic and international tourists throughout the year. Tourism supports hotels, restaurants, guides, jeep operators and other small businesses in nearby communities, making an extended closure economically significant.

However, officials have emphasized that visitor safety and fire-control operations must take priority.

Travelers with plans to visit Mount Bromo should confirm the latest conditions through Bromo Tengger Semeru National Park and local authorities before beginning their journey. Visitors should not attempt to enter closed areas or approach active firefighting operations.

Environmental Damage Under Review

Officials will need to assess the full environmental impact after the fire is contained.

Wildfires can destroy protected grasslands, native plants and wildlife habitat while leaving hillsides vulnerable to erosion. Recovery may take months or years depending on the intensity of the fire and the types of vegetation affected.

Authorities are continuing aerial and ground operations as they work to contain the remaining hotspots and prevent the blaze from spreading farther through the national park.
