I climbed Kilimanjaro with Lava Expeditions during the rainy season. I flew to Nairobi in Kenya and spent several days there. At my hotel in Nairobi I met the rest of the group with whom I would spend the next week. We all travelled on the bus together for a 6-hour journey into Tanzania and then Arusha , a quiet town. After we arrived at our hotel in Arusha , we had dinner and a few drinks. Then we were introduced to more members including Taddeus Minja, the main guide, who was very experienced -- climbing Kilimanjaro runs through the generations of his family. The next day the Lava Expeditions members checked if we had the correct and enough clothing for our expedition on Kilimanjaro. Only one person needed to bring more clothes. After that we set off, walking in the rain through the beauty of the rainforest, all the way to the first camp. I was happy the next few days as the view was so wonderful and changed every day. I suffered a little during the trip and I felt so tired. But the members of Lava Expeditions provided me with lots of encouragement, which was one of the best memories. Finally we reached the top of Kilimanjaro in bright blue skies. I felt excited about climbing Kilimanjaro and the feeling didn't change during my trip. Lava Expeditions looked after me so well that I was deeply thankful for their help. How did the author get to Nairobi? A) By bus. B) By train. C) By air. D) On foot.
