One climber, Ryan Sean Davy of South Africa, however, found himself in a rather uncomfortable position when he discovered he didn't have enough cash for a permit, "because of hidden costs."
Feeling that he couldn't let down all those who "had faith in him" and let "all the help and training" be in vain, he decided to engage in a daring idea: to climb the mountain without paying the fee.
Davy's off-the-record adventure, however, ended early, after he was discovered hiding in a cave.
"I saw him alone near base camp so I approached him and he ran away," Gyanendra Shresth, the government liason officer at base camp, told AFP.
"I followed him with my friend and found him hiding in a cave nearby," he continued. "He had set up camp in an isolated place to avoid government officials."
Davy now faces the possibility of jail time and monetary penalties, likely twice as much as the climbing fee; these measures may also come with a 10-year ban on climbing in Nepal.
One of Davy's friends posted on his Facebook wall, asking for others to help.
"Ryan is looking at a $22000 fine," Michele Whitehead wrote. "Mohan a friend in Nepal suggested we contact the Consulate in Nepal.
"Ryan will probably [be] jailed till everything is sorted. We need to start the funding. I will find out about the funding today. If any one of his American friends can also contact me regarding a funding page."
