Poon Hill, is a famous viewpoint in the Himalayas, and one of the only places on the Annapurna Circuit where Annapurna I (8091m – 10th highest mountain in the world) may be seen, as well as Dhaulagiri.
A modest entry fee to the Poon Hill, a 50 minute uphill walk from Ghorepan, is requested in early morning. In usual Nepali style a teashop may be found at the top.
Technically straightforward, the path to Tilicho Lake is nevertheless more demanding than the rest of the Annapurna Circuit. It is also quite popular, and when I arrived from Manang at 2 pm the Tilicho Base Camp Hotel was full (a new hotel is under construction nearby). In that case people are offered to sleep in the dining room, as is common in the high-mountain tea houses with no alternative accommodation.
Tilicho Lake Trek two-day itinerary as walked in October 2015:
Day 1: Manang-Tilicho Base Camp Hotel (4200m) Day 2: Tilicho Base Camp Hotel- Tilicho Lake (4920 m)-Tilicho Base Camp Hotel (lunch)-Blue Sheep Lodge, Shree Karhka (app. 4000) Day 3: Shree Karkha-Letdar- the Annapurna Circuit
I did not find the route genuinely exposed: Though the scree-slopes look exposed from afar, and very steep looking down on them, I think that one could quite easily auto-arrest on the slope in the unlucky (and quite unlikely) event should one fall from the trail. I even met, and crossed a couple of yaks on one of the scree slopes (I took a step up on the scree slope and let the yaks pass on the trail).
However, those with fear of heights may have issues, and I saw a (very fit by the way) couple turn around.
