Recently, my boyfriend and I explored the Portland Classical Chinese Garden, http://www.portlandchinesegarden.org/. It is fantastic. I really don't think I can describe it well enough, so I will just add the pictures below. Honestly, the pictures do not do it justice.
Enter the Portland Chinese Garden.
Take a walk down one of the many paths.
Enjoy the foliage on your stroll.
Take a rest by the waterfall.
Enjoy some traditional Chinese tea at the Tao of Tea. The options are almost limitless.
As you leave the gardens, look around at all the unique rock. This rock is very rare, and it comes from the bottom of only one lake in China. Actually, the rock has all been mined out of the lake.
