The monastery of Noravank and the upper Amaghou Va by Walter
Just visited (July 2014). Easy to see if you are in southern Armenia - the best place to start journey seems to be Yeghegnadzor - it is possible to hire a taxi there (the most convenient way, average cost of taxi in Armenia is around 100 AMD per one km). It is also possible to go by marszrutka (local bus) to Areni, before that town there will be a side road to Noravank (8 km walk).
The whole monastery is beautifully situated in high mountains, landscapes are amazing. In the monastery don't forget to see the upper church of Surb Astvatsatsin (Holy Mother of God) - the steps are outside. As in whole Armenia fresh water is availabe from the source within monastery premises.
