This is a fairly recent story although it wasn't covered by the Australian news.
In April 2014 two young Dutch girls holidaying in Panama went for a hike on a maintained path to the top of the mountain range Near Boquete Panama. They did not return. A large scale search was undertaken but because they did not inform anyone of their intentions the searchers had no idea where to look.
Months later their remains were found in a river deep in the jungle. Information found in the girls phones and camera helped investigators to piece together the tragic story.
Apart from making a few early mistakes which saw them become lost the girls did exceptionally well to keep themselves alive in the jungle for over a week. Saving their phone battery power by turning them off and only back on to check for a signal, staying in an open area to be seen from the air and setting out help signals on the rocks, sadly that help was much too late.
There are lessons here for us all on letting people know your route and intentions and time lines and packing enough gear to be prepared for the unexpected. Also don't let your bravado override your common sense. If you are lost just turn around and go back the way you came until you are in familiar country.
This story was covered in depth from the time the girls went missing until their remains were found by American Journalist Jeremy Kryt. He even travelled to Panama hiring guides and walking the route to investigate the true story of what happened. I have included the link to the Daily Beast full story which I have found to be the most accurate. Also a Utube video link. there are other sites which cover the story and Utube videos as well. I watched a video of some men walking the same route taken by the girls in the rain. It looked horrendous!. It's not somewhere you would wander into by accident.

Having hiked in similar jungle terrain myself I found this story very interesting. I would be interested in others views on what went wrong given the few clues available.
