sea kayak Trip Classification III B.
White water river scale class II.
This is stretch is similar difficulty to eagle watching trips on Skagit River- Current about 3-5 mph with occasional 1-2 ft waves.
Float 20 miles down the Yakima river thru a wonderful canyon from Ringer Loop (5 miles S of Ellensburg) to Roza Dam recreation area (5 miles north of Yakima). Lunch stop and hike at Umtanum creek. The area’s ecology is called shrub-steppe (semi desert) and we will see spring flowers including Lupine and Balsam root, and possibly mountain goats and rattlesnakes. The canyon is up to 1000 feet deep, surrounded by spectacular basalt cliffs.
If you would like to bicycle thru the same stretch, the next day is the “your canyon for a day” bike tour
