Closure of Semeru Hiking Trail Extended, Bromo Tourism and Ranu Regulo Remain Open

The closure of Mount Semeru's hiking trails has been extended. This decision was made by the Bromo Tengger Semeru National Park Center (TNBTS) to ensure the safety of climbers from the threat of extreme weather forecasted throughout December 2025.

The warning from the Meteorology, Climatology, and Geophysics Agency (BMKG) is the primary basis for this policy. 

Head of the TNBTS Center, Rudijanta Tjahja Nugraha, confirmed the closure of Semeru climbing is indefinite. 

"Regarding the potential for extreme weather throughout December 2025, the TNBTS Center has decided to extend the closure of Mount Semeru climbing until an undetermined timeframe," stated Rudi.

This decision is outlined in Announcement Letter Number PG.21/T.8/TU/HMS.01.08/B/12/2025, released Tuesday, December 9, 2025. 

This step aims to reduce the risk of emergencies such as heavy rain, landslides, and strong winds, natural phenomena common in volcanic landscapes that can change drastically within minutes. 

For climbers who have purchased tickets via the online booking system on the official website bromotenggersemeru.id, there is flexibility. 

Rescheduling is available for bookings covering the period November 20 - December 18, 2025. 

"The mechanism will be announced once there is certainty regarding the reopening of the hiking trails," said Rudi.

Meanwhile, other tourist activities in the TNBTS area continue. The Mount Bromo and Ranu Regulo areas remain open to visitors.

This policy provides alternatives for tourists wishing to experience the natural atmosphere of Tengger. However, vigilance remains essential. 

Rudi reminded tourists to avoid disaster-prone areas, especially around the Bromo Crater, an area monitored for earthquakes and volcanic activity.

Furthermore, TNBTS emphasized that any form of illegal climbing activity will be dealt with according to the law. 

This appeal was conveyed to ensure safety and maintain the preservation of the area's ecosystem. 

"We urge the public, visitors, tourism service providers, and related parties to heed and implement this with full responsibility," he stated.

Amidst dynamic weather and ongoing volcanic activity, TNBTS hopes this policy gives the Semeru landscape space to breathe.

Climbers may return someday when the hiking trails are declared truly safe.
