Trek to Makalu can be cut short by taking direct flight to Tumlingtar, a small village located on a plateau. The trek from Tumlingtar at barely 390m to Makalu Base Camp at 4,800m is a long and arduous as vast range in temperatures is confronted, from steamy in the lowlands to snow storms at high altitude.
Walking north up the Arun river to Sedua and Num, then crossing Barun La(4110m.)into the upper Barun khola valley for a close look at Makalu. You can put together an even wilder trek by crossing Sherpani Col and west Col into the upper Hongu valley. The highest point of this trek is Salpa Bhanjyang and also we can visit Hindu holy call Lake Salpa holy Lake(3414 m.).

The tempting views of Arun river and valleys can be seen on the way of trekking terrain.
