The Machame Route is known as the "Whiskey Route" in comparison to Marangu's "Coca Cola Route". This is because Machame is a more difficult route, and does not have sleeping huts for accomodation. Machame is the second most popular route on the mountain.
The Machame Route climb can be done in a minimum of six days (five nights) on the mountain. However, it is most often tackled over seven days (six nights), for a better altitude acclimatization schedule. The success rate is significantly higher when using the seven day route.
The trek begins at Machame Gate, located in the southern base of mountain, which is just a short drive from Moshi or Arusha. The hike starts within Kilimanjaro's lush, fertile, montane rainforest. As you might expect, the lower slopes receive a quite a bit of precipitation. The trail may be steep and slippery, so trekking poles are advised. As the route heads toward the Shira Plateau, the trees disappear and are replaced by low brush in the heather zone. Then the route climbs high to the volcanic plug, Lava Tower, before dropping and circling below the South Icefield. This circular pathway from Barranco to Karanga to Barafu is known as the southern circuit. As it traverses halfway around the mountain, climber's are exposed to great vistas. The long, strenuous approach to the summit is made from the east through endless switchbacks up increasingly loose gravel until we reach the crater rim at a mark known as Stella Point. Then the route is relatively flat for another hour to Uhuru Peak - the top of Mount Kilimanjaro. The quick descent follows the Mweka trail.
The Machame Route is approximately 62 km/ 37 miles from gate to gate. It is designed for physically fit people with some hiking experience, but plenty of first time trekker use the route as well and do just fine. It is rated as one of Kilimanjaro's better routes and thus is recommended. It is certainly a better choice than the typical tourtist's route - Marangu.
