Your first stop should be the Royal Society for Protection of Nature's (RSPN) Black-Necked Crane Information Centre, which has informative displays about the cranes and the valley environment. You can use the centre's powerful spotting scopes and check what you see against its pamphlet 'Field Guide to Crane Behaviour'. If the weather's iffy you can browse the library and handicraft shop, and watch videos at 10am and 3pm (Nu 200). This is also the centre of the valley's fledgling ecotourism initiative and they can arrange mountain-bike hire (Nu 700 per day), a local guide (Nu 300), an overnight stay in a local farmhouse (Nu 500) or lectures on the local ecosystem.
Really appreciate YANA's professional organization of the entire trip. Could not imagine how a trekking trip could such be well organized - more or less like a 5-star hotel with the only difference of we were at more than 3,000 above sea level. Special thanks to Yeshey and the chef who had given tons of assistance when I was descending due to attitude sickness. - Simon Liu, Hong Kong
