Oregon Observatory at Sunriver - we live in a great place for stargazing, so why not go to the observatory and see the night sky? No smog or light pollution to obstruct your night views, plus the observatory puts on events and presentations.
One of my favorite waterfalls in the world, Proxy Falls, located in Central Oregon's Three Sisters Wilderness. The short hike to this gorgeous waterfall features Rhododendrons and trillium in spring as well as the vibrant foliage of vine maples in autumn. Proxy falls is stunning!
