The Seti Khola rises on the South East slopes of Machapurchare and then flows south as a fairly typical Nepalese mountain river, it is dammed for Hydro Electric Power just above Pokhara and then shortly afterwards it disappears in to a deep and very narrow chasm to reappear again in a wide valley a few kilometres below Pokhara - so be careful where you get in! From the recommended put -in at Dule Gouda it flows through a spectacular almost eerie, board river plain, at times meandering in braided channels at other times incising the plain leaving 100 metre high river cliffs. The rock here is reminiscent of buildrers comglomerate - pebbles and small boulders embedded in a coarse sand matrix but more resistant to erosion than it appears at first glance. After Khaireni the Seti enters a typical Nepali valley initially passing through some small narrow gorges. It then winds a lot between interlocking spurs of the high green hills, before entering a straighter jungle corridor, with only a sparse local population. This corridor continues all the way to the Trisuli, interrupted only by a short narrow section, which precedes the wide Mardi Khola confluence at Dhaumali. Features to note on the river include quit a range of birds, from many vultures on the upper section to Kingfishers on the lower section. The jungle corridor has lot of hanging, green vegetetion on all sides and has several narrow velleys, which could be explored on foot.
