A full moon is the lunar phase when the Moon can be seen in its entirety from Earth. This occurs when Earth is positioned directly between the Sun and the Moon (more exactly, when the ecliptic longitudes of the Sun and Moon differ by 180°). So, all of this technical stuff means that once every month the Moon appears to be completely round and beautifully bright in the night sky. It occurs about every 29 days, so you have 12 times in a year to witness the full moon. That's one opportunity every month to witness this beautiful celestial event from the summit of Mount Kilimanjaro.
Firstly, you’ll be accompanied and guided in your night-time trek by the bright light of the full moon. It illuminates your six-hour journey up to Uhuru Peak, making the glaciers glitter and the rolling clouds below you glow. The moonlight also makes the earth beneath your feet glisten. Sounds like a dream, right?
Secondly, a practical reason for climbing during a full moon is that its brightness (when paired with a clear sky) improves visibility throughout your Kilimanjaro trek, especially during your summit attempt.
Thirdly, climbing Kilimanjaro during a full moon offers you magnificent night views of Kibo from most of the overnight camps.
