A co worker hiked it about 6 months ago. he told me the tribe at the bottom had quads down there. I am not sure if those are the ones for the tour or not but he said everything had to be flown by helicopter there. All of the tribes supplies, parts for the bikes, gas etc.. I don`t know if they have any that you can take your own bikes to or how you would get them there. something that would have to be looked into
