The Ulvetanna in Antarctica, is one of the most remote and challenging mountains in the world.
It stands at more than 2,900 metres tall and temperatures can plummet to - 40 degrees.
But a team led by CBBC's Fierce Earth presenter Leo Houlding, has managed to conquer the peak and turn the adventure into a film called The Last Great Climb, which is out next month.
Leo's entire trip was monitored by kids from schools in the UK and Leah went to find out about it.
