In one of my last days in Bumthang I was to go off to venture to Shugdrug, a small temple in the side of a cliff. The walk was an easy one through a small forest like trail. You'll see in the second picture a little building which inside has a prayer wheel being powered by water. If you look closely at what the water is coming out from you'll notice a very common like object for Himalayan countries. A phallus.
The temple itself was small but very historic, with a meditation cave used a long time ago from the guru rinpoche. Unfortunately photos were not allowed inside.
