Sahalie and Koosah Falls are stunning! There is a moderate 3 mile hike around the falls on a section of the McKenzie trail that provide 360 degree breathtaking views of the falls. For those who do not wish to hike there are view point for each waterfall right off the parking lots.
For our more adventurous friends the Mckenzie River provides class three rapids and beautiful crystal clear cold water to play in!
The McKenzie river goes underground through lava tubes and re-emerges at Blue Pool, a turquoise, ice cold, pool. It is a 3.5 out and back moderate trail that is very worth the view!
If you want to get a little PNW crazy and don't mind naked hippies the hot springs are a fun, unique spot. It is a short hike into the springs.
