A Brazilian tourist who hiked to an abandoned bus in Alaska made famous by the film 'Into the Wild' has been rescued after running out of food.

Alaska State Troopers discovered the man at his campsite near the infamous 'Magic Bus', just outside of Denali National Park.

The tourist, who has been named as 26-year-old Gabriel Dias Da Silva, activated his emergency beacon and was rescued by a trooper helicopter on Thursday.

Da Silver had been able to cross the river on the way to the bus, where American hiker Christopher McCandless died of starvation in 1992, but conditions had worsened when he tried to return.

Trooper spokeswoman Megan Peters said: 'The river was open and raging. Apparently when he had headed out about a week ago, ice bridges were still up'.

The abandoned and rusted bus was used by McCandless as his final campsite and has become a shrine for fans of both the book by Jon Krakauer and the 2007 movie based on its events.

Both chronicled the life and death of McCandless who hiked into the Alaska wilderness with little food and equipment and spent the summer living in the bus.

Denali Borough officials voted to ask the state to remove the Magic Bus, along the Stampede Trail, earlier this year though state officials have said they will not remove it

His body was discovered an estimated two weeks after he died in 1992 by hunters looking for shelter.

McCandless' diary was found alongside his body. A final diary entry titled 'Day 107' read 'Beautiful Blue Berries'. Days 108 through 112 were marked only with slashes, and there was no entry on day 113.

Da Silva joins joins a long list of hikers to the bus who have had to be rescued.

In February this year five Italian tourists, one with frostbitten feet, were rescued after hiking to the site.

Two of the treks have been fatal. Last summer, a woman from Belarus died after being swept away in the Teklanika River on her return from the bus.

In 2010, a woman from Switzerland also died in the river in a similar incident.

In March this year frustrated Denali Borough officials voted to ask the state to remove the bus and rejected a bid from victims' relatives to build a bridge across the Teklanika, local media site Anchorage Daily News reported.

State officials have said they won’t remove the bus but will consider posting warning signs.
