We attempted the summit on the very early morning of the 6th day (around midnight). It took us about 6 hours to ascend. The full moon made the headtorch unnecessary and the night ascent a beautiful experience. The first milestone was Stella Point (5.685 m), which is on the crater rim. Following Stella Point, the trail continues for another 30 mins to the summit - Uhuru Peak.
The descent back to Barafu took roughly 4 hours. We 'scree slided' down the slope, which entails skidding/running down the loose gravel at medium speed. Then we took a short brake at Barafu and continued downwards through the alpine desert and ensuing moorlands to Mweka Camp.
