DAY 1: Umbwe trailhead
Drive to the Umbwe trailhead at 1800 m. The route initially follows a forestry track winding up through the natural rain forest. It then narrows and steepens to climb the ridge between the Lonzo and Umbwe rivers. The first campsite is in the forest by some rock overhangs at 2940 m, (5/6 hours walking).
DAY 2: – Barranco
Shortly after leaving the camp the forest ends and the path continues along a narrow spectacular ridge. Above, the sheer 1000 m of the Breach Wall appears and disappears as the afternoon mists roll up the Great Barranco. From the Umbwe ridge the route descends slightly to the Barranco Hut and our camp in the valley floor at 3900 m, (5/6 hours walking).
DAY 3: Barranco – Karanga Valley
A short scramble to the top of the Great Barranco and then a traverse over scree and ridges to the Karanga Valley (4000 m, 3 hours), beneath the icefalls of the Heim, Kersten and Decken Glaciers.
DAY 4: Karanga Valley – Barafu Hut
After climbing out of the Karanga Valley the trail ascends a ridge to the Barafu Hut, a bleak location with little vegetation at 4600 m, (3 hours walking).
DAY 5: Barafu Hut – Rebmann and Ratzel Glaciers – Uhuru Peak – Mweka Hut
An early start for the ascent to the rim of the Kibo Crater between the Rebmann and Ratzel Glaciers, (4 hours); the last section before the rim can sometimes be snow-covered and an ice-axe or ski stick is useful for balance. From here a further hour leads to Uhuru Peak, from where there are often fine views of Meru to the west and the jagged peak of Mawenzi to the east. After a short time on the summit you descend to the Barafu Hut for a rest and lunch before continuing on down to camp at Mweka Hut in the giant heather zone on the Mweka route.
DAY 6: Mweka Hut – Park Gate
A 3-4 hour descent through beautiful forest brings you to the Park gate.
