Is bottled oxygen necessary or available on the climb?
Bottled oxygen is not routinely available on this climb and not included in the price of the trip. The most immediate treatment for serious altitude sickness is rapid descent, which is always possible on Kilimanjaro. Virtually no climbers on the mountain carry oxygen. If upon reaching the final campsite before the ascent your guide judges you to have serious symptoms of altitude sickness, you will not be permitted to attempt the final climb. Oxygen may be available on an emergency basis or at an added cost, but not as an aid for climbers who have not acclimatized adequately on their own.
