This would be your second acclimatization day that requires about 6 hours of trekking to an altitude of 5100 meters. After breakfast we ascend Nagerjun (5,100 m), a hill located on the flanks of the Chhukung valley directly above Dingboche. The main aim is to climb high and sleep low. The foot path becomes steep at times; resulting in a physically challenging day- ascending the hill could take up to 5 hours at altitude. From this altitude there are good views of Lobuche East (6,119 m), Lobuche west (6,145 m), Tangoche Peak (6,367 m), Thamserku (6,608 m), Kangtega (6,685 m) and Ama Dablam (6,856 m). On a clear day you could even see Makalu, the world's fifth highest mountian, including great views of the Pheriche valley. After a short rest we will start the descent back to Dingboche - the walk at altitude takes about 2 hours. After lunch you should take a well deserved rest, afternoon temperatures could drop rapidly as the sun sets over the mountain tops. We will spend a second night in Dingboche. Overnight at Guesthouse with Breakfast, Lunch & Dinner basis.
