I contacted Third Rock Adventures for Annapurna Base Camp Trek. I had few more days, so Naba suggested adding Poon Hill trek with ABC trek. It was wonderful time doing the trek experience many beautiful things. I had enough time to enjoy the view from the base camp. The rooms selected for us were good enough and the food were freshly cooked and delicious. The trek is demanding, no doubt about it, but if you do not get elevation sickness it is also quite manageable. This was my first experience trekking in Nepal and I am happy with my choice of Third Rock but I have learned a lot during this first experience and so will do a few things differently next time.
