    I did this as an extension to the Bechler reiver trail. Very Impressive waterfall and the scout pool on the other fork of th eriver makes a great warm water soak.

    "This is a long, forested route to a spectacular isolated waterfall; best suited for a long day hike but can be an overnighter. Union Falls is defi nitely one of the most spectacular waterfalls in the park and well worth the long out-and-back hike to see it. This trail gets fairly heavy use, especially from stock parties, and is in excellent shape the entire way. The first 1 mile is flat and easy as it follows the stream leaving Grassy Lake Reservoir and then the Falls River. Just before the ford a trail heads off to the left (west) to the Cascade Creek Trailhead, where you could also start this hike. The ford is long but only knee-deep in August." Read more
