An adventurer, trying to raise a million pounds by climbing Everest and leaving a red nose on the top, is nearing the summit.
Daniel Hughes is doing the challenge for Comic Relief and here on Newsround we've been following his progress.
Mount Everest is the highest mountain on earth at almost 8,900 metres tall.
Conditions are really tough for climbers because there is less oxygen that high up and it is really cold.
Daniel sent us an update as he and his team were preparing to climb to the summit. Check out the video to get a tour of their camp!
