Myself and my two friends decided to travel to Kilamajaro to complete the machame 6 day route. Friends of ours had completed it the year previous with Monkey Adventures. They swore by them and they were not wrong our whole trip was smooth and highly memorable. The guides are knowledgeable (ours was Remmy who was excellent), the chef, porters and assistant guides all know their roles and are so friendly and outgoing.
Would 100% recommend to a friend!
