Machame Route has a nick name “Whiskey Route”, and despite the fact that is relatively short, it is not easy to climb. It is not technically difficult, but it is pretty strenuous, with many steep trails that require extra strength and physical condition to pass.
But, Machame is very rewarding route, with spectacular sceneries such are Lava Tower, Barranco Wall, Shira Plateu which is why this route is considered the most scenic one.
The route starts at Machame Gate, and thru the beautiful rainforest, heading West around Kibo. There are 6 and 7 day options to trek this route, but note that the shorter one does not include acclimatization day to get used to the high altitude conditions. Machame is also the route where you spend the nights in tents, and requires a lot of strengths to complete. Descend is at Mweka gate.
