Tamanawas Falls

Tamanawas Falls is a short 3.8 mile (6.1 km) round trip hike. I would consider them a block from waterfall even though they do completely come away from the face of the cliff. In fact if you were inclined you could likely traverse behind the waterfall.
I traveled to the falls in early May and found that their was quite a bit of snow to be found. The hike begins at about 3,000 feet (914 m) in elevation and gains only 500 feet over the course of the trail. The trail can be a bit tricky in the winter but the footpaths should be somewhat helpful. For better directions see the link below.
As for the falls they are about 100 feet (31 m) and take on a fairly large volume. I did not experience a large amount of overspray from the falls but I also did not get all that close to them. Overall this falls is certainly worth the drive and short hike.

Directions:
From Hood River take exit 64 from Hwy 84. Travel south on Hwy 35 for approximately 25 miles. The turnoff for the trailhead is about 1.5 miles after the Polallie Creek Campground.
