TNBTS: Tengger Caldera Ring Road Development 65% Complete, Targeted for October 2026

The Bromo Tengger Semeru National Park Agency (TNBTS) has reported that the development of the Tengger Caldera Ring Road (JLKT) within the national park area has reached 65 percent completion and is targeted for completion in October 2026.

“The work will be completed in October, and the latest progress on the JLKT has reached 65 percent,” said Head of the TNBTS Agency Rudijanta Tjahja Nugraha in Bromo, East Java, on Monday.

He said the ongoing work includes area clearing as well as the installation and painting of boundary posts separating the road from the grassland areas.

Meanwhile, the upcoming progress will involve installing wire slings on the fencing and traffic signs.

“The current focus is on installing the posts first, while the rest involves constructing the route,” he said.

The JLKT spans 13 kilometres in length and 18 metres in width, stretching across the Tengger Caldera area towards the viewpoint at Simpang Dingklik, which falls within the administrative territory of Pasuruan Regency, East Java.

The development of the JLKT area is part of efforts to strengthen local wisdom and the tourism sector within the TNBTS area by aligning with nature conservation efforts and preventing damage to sites considered sacred by the Tengger community.

Therefore, the TNBTS Agency emphasised that the development of the JLKT area continues to observe and conform to conservation rules and norms.

Additionally, Rudi said that the JLKT work is separate from the development of rest areas at three locations, namely Cemorolawang, Watu Gede, and Dingklik.

Furthermore, he said, the development of the rest area at Cemorolawang is already underway, with facilities such as tenant stalls and toilets having been built.

“Then at Watu Gede, where there is a water reservoir, that is also visible as a rest area. One more is at Dingklik, just before the ascent to the viewpoint. So two locations are in Probolinggo (Cemorolawang and Watu Gede), and one other is in Pasuruan Regency (Dingklik),” said Rudi.
