One of the most beautiful attractions in Portland is the city's Chinese Garden named Lan Su.  In North America there are really only two Chinese Gardens I liked a lot.  This one and the one in Montreal.  Needless to say, this place is a must for anyone visiting Portland.

Per the official garden guide, the rockery is designed to appear as rugged mountains in the distance, complete with waterfalls ad cascading streams.

The entrance to the Lan Su Chinese Garden is called the "Moongate"  This picture was taken from what is called the "Fragrance Courtyard".
