We just completed the 7 day Machame route with jambokili tours, couldn't have had a better experience. Our guides were very attentive and helpful, my partner had altitude sickness and they constantly checked in with him about how he was feeling and did oxygen level and general health checks for both of us each night. Summit night was the most difficult walk either of us has ever done, but the team of three who came with us were really encouraging, we both made it to the peak and the guides pretty much carried me down the summit after. The team of porters, chef and other staff had the car ready by the time we finished walking each day, and we were overwhelmed by the amount and quality of food provided each day. We hope to come back to Tanzania soon, and would definitely book with jambo kili tours again.
