Day 17: Gokyo (4720m)(Rest and Exploration Day) We rise early for an ascent of Gokyo Peak (5360m), a straight-forward but steep climb and tiring due to the altitude. The walk up will take just over two hours and the reward is one of the best panoramas in the Khumbu. From the rocky summit, four 8,000-metre peaks can be seen - Everest (8848m), Cho-Oyo (8153m), Lhotse (8511m) and Makalu (8481m). Countless other towering snow-capped peaks and rock spires fill the horizons including Gyachung Kang (7922m) to the east of Cho-Oyo, Cholatse (6440m), Taweche (6542m) and Kangchung (6103m). In addition, there’s a bird's eye view of the Gokyo lakes and the huge creaking Ngozumpa Glacier, now cutting halfway across the world and snaking its way down the valley far beneath. Time permitting, we may also follow the lateral moraines of Ngozumpa Glacier past Kangchung Peak to a point where Gyubanare Glacier joins in and from where climbing the ridge to the left of the small trail gives us excellent views of Everest’s north face.
