It was clear from the start of the expedition that Ari was very professional indeed. His knowledge of the mountain was stunning and was able to direct and manage a team of mixed climbers whom were at different ages, abilities and fitness levels. Above all though was his passion for the Tanzania. At every point, he identified age old lava rocks, domestic birds and animals and it's beautiful history. He was pleasure to be with. If you are planning a trip to Tanzania for a trek up Kilimanjaro or a Safari, then I highly recommend this guy. He will look after you very well indeed.
