I brought my hiking club to Umtanum Falls last year. Everyone seemed to like it so I volunteered to host another trip in the area this year, this time up Umtanum Canyon from the other end by the Yakima River. We hiked up the canyon about 3 miles then we climbed out and onto Manastash Ridge. Manastash Ridge basically seperates the canyon from interstate 90 and Ellensburg. A good time was enjoyed by all - except for the final climb off the ridge back down to where the cars were parked. Very steep with only a boot path to follow. A good trail here would be a wonderful addition to an otherwise spectacular place to hike.
