Just arrived back to Canada from a 7-day trek on the Machame route with Climb Kili. Found they were a fantastic operator and priced reasonably. Very knowledgeable and energetic/friendly guides who were very concerned for our safety but also very committed to getting us to the summit. Same with the porters- happy to see that they were appropriately outfitted after hearing all the horror stories of lower-cost operators skimping out on pay and then subsequently being horrified at seeing underdressed cold porters from other companies on our route. Our guide even told me that ClimbKili sends him on regular week-long training sessions which I think is almost unheard of… understandable that other guides were asking ours about jobs at ClimbKili during our trek! I recall researching all the different tour operators a few months ago and feeling very overwhelmed by choice, particularly since I was a solo female traveler…ended up being very happy with my choice. Hope this review helps any other solo travelers out there in the same boat!
