I did the 8-day Lemosho route and really enjoyed it - rainforest to glacier, with plenty of time for acclimatization and sightseeing along the way. My guide Herment Mosha was outstanding! He was friendly, fun, and knowledgeable. He's climbed the mountain more than one hundred times and was a great motivator and inspiration to our group. He also took the time to point out different kinds of plants to our group each day and explain what was special about them. I also saw him pick up trash as we were hiking that did not belong to our group. It is clear he loves his job and has a great respect for the mountain. I feel very lucky to have gotten to climb the mountain with him. The Climb Kili staff were all very friendly and helpful. I also did a safari and a Zanzibar trip with Climb Kili while I was there and recommend them to anyone going to Tanzania.
