A tourist slipped inside an active volcano and has now been trapped inside for three days with rescue teams so far unable to reach her.

Distressing last footage shows Juliana Marins after she fell from one of the most dangerous hiking paths in the world into the 12,000-foot-high active volcano. The 26 year old had been on a trek to scale Indonesia's Rinjani volcano on June 20 when she slipped and plunged nearly 1,000 feet down the peak. She is claimed to have been stopped and waited on a trek led by guide Ali Mustafa after saying she was too tired to go on. Ms Marins who works as a publicist and pole dancer, reportedly screamed as she lost her footing.

When the guide returned with the other five hikers Juliana had gone but the hikers then saw her where she had landed and was unable to climb back up. Drone footage shot by another tour group shows her stranded in the volcano apparently stuck fast in a crevasse unable to free herself.

She is looking confused and dazed and apparently able to move just her arms and her torso with her legs curled at a strange angle as the film ends. She is wearing just jeans, a T-shirt, gloves, and trainers despite the altitude and intense cold. Rescuers' attempts to reach Juliana were abandoned on June 22 after fog reduced visibility to near zero, local authorities reported.

Spokesman for the East Lombok Police, Nikolas Osman, said Juliana was in a group going to the summit of Rinjani. "The victim experienced fatigue and the guide at that time advised her to rest," he said. "Then the five guests in the tour group were taken by the guide to continue the journey."

Today a tour guide said that the woman was spotted again further down the slope and rescue teams are struggling in difficult conditions due to the terrain and thick fog. Her family in Niteroi, eastern Brazil, deny Indonesian claims that they had been able to airdrop food and clothing to her. Instead they say a botched rescue bid was abandoned over the weekend when a helicopter crew realised the rope they had was too short.

An Instagram pageresgatejulianamarinsset up by her family giving updates has said that experienced local mountaineers are heading to join the search. It stated "We have confirmed information that two well-experienced mountaineers from the area are headed to the scene of Juliana's crash.

"We don't have information on whether they will be able to continue the rescue operation overnight, but we do know that there is good backup with specialized equipment to accompany crews already on site."

Brazil's foreign ministry said in a statement: "Since being alerted by her family, the Brazilian embassy in Jakarta has mobilised local authorities at the highest level.

"This has brought the rescue teams to the area of the volcano where the fall took place in a remote region about four hours away from the nearest urban centre."

Juliana's family remains hopeful, and her sister Mariana Marins said: "I believe my sister is alive." She had been on a three-month backpacking trip through Asia when she disappeared.
