A Brazilian tourist has been found dead on an Indonesian volcano after a dramatic four-day search amid claims her guide left her behind.

Juliana Marins, in her mid-20s, was hiking with a group on the active Mount Rinjani volcano on June 21, when she reportedly slipped and fell from a steep section of the mountain, according to Indonesian authorities.

Marins survived the initial fall.

Rescuers reported hearing her screams for help on Saturday.

Drone footage also appears to show her distressed but alive and moving on Saturday.

She could be seen sitting and moving around in grey soil, far below a hiking path.

Indonesian authorities said Marin fell from a cliffside but did not fall into the crater.

The area is particularly difficult due to loose volcanic sand, the head of the local search agency Barsanas, Muhammad Hariyadi, told Reuters.

“The soft sand made it difficult to retrieve her using ropes,” he said, adding the unstable footing in the area severely delayed access to the Juliana.

More than 50 people were involved in the rescue.

Rescue teams first heard her cries and spotted her alive via drone, but rough terrain and bad weather delayed rescue efforts.

“After four days of work, hindered by adverse weather, terrain and visibility conditions in the region, teams from Indonesia’s Search and Rescue Agency found the body of the Brazilian tourist,” the Brazilian government said in an official statement.

“Today, the rescue team managed to reach the place where Juliana Marins was,” Marins’ family posted on social media.

“With great sadness, we inform you that she did not survive.”

Located on the island of Lombok in West Nusa Tenggara province, the 3726-metre active volcano is a popular destination for international trekkers.

According to Brazilian newspaper O Globo, Juliana became separated from her group during the hike and fell in a remote section of the trail near Cemara Nunggal.

This stretch is known for its instability and lies between 2600 and 3000 meters above sea level on the climb toward the summit.

According to her guide, 20-year-old Ali Musthofa, Juliana had asked to pause briefly due to fatigue, O Globo reported.

He claims he walked ahead “three minutes” before realising she wasn’t following.

Musthofa, who has been leading treks since November 2023, denies any negligence.

“I did not abandon Juliana,” he told local press.

“I went ahead to wait, just a few minutes.

“When she didn’t arrive, I looked back and then I saw her light down in the darkness.”

Her body was located by one of the search teams after descending more than 150 metres into a rugged ravine.

Authorities have not yet confirmed her exact cause of death.

Her family is now working to bring her body home to Brazil.

The latest incident has renewed scrutiny on volcano safety across Indonesia.

Mount Rinjani has recorded several tourist deaths in recent years.

In May, a Malaysian hiker died after falling from a cliff and in December 2023, 23 people were killed when Mount Marapi erupted.
