Beautiful fairylandlike waterfall along the Pacific Crest Trail on the west side of Mount Hood. You can get there by hiking the 7-mile Ramona Falls Loop, but keep in mind that you have to cross the Sandy River on logs.

At the peak of Tom, Dick and Harry Mountain there is a great view of Mt. Hood and Mirror Lake. The trail up to the peak requires a moderate effort but it is worth it for the views at the top.

The trail winds down to the river that rushes from Mount Hood. Use the rocks to cross the water without getting your feet wet or just walk through it, if you don’t mind wet feet.
