The Makalu trek starts lower than almost any other major Himalayan route. From Num, at about 1,560 m, the trail plunges to a suspension bridge over the Arun River, under 1,000 m, then climbs the far side to Seduwa. The Arun cuts through the Himalaya from Tibet, and the valley is deep, warm and green, with sal and chilaune forest, banana trees and cardamom plantations.
Most villages here are Rai, one of the Kirat peoples, with Sherpa settlements higher up near Tashigaon. Houses are stone and thatch or tin, with maize drying under the eaves and chickens in the yard. The national park check post at Seduwa is where permits are checked. Lodges are family homes with a few rooms added, and the welcome is warm.
These days are hot and humid compared with the high valley, with big climbs and descents. Start early, carry plenty of water and use the evenings to talk with your hosts about life in a valley that has only recently been reached by road.
