Umtanum Creek is a tributary of the Yakima River in central Washington state. It flows generally eastward from its headwaters in the eastern slopes of the Cascade Range, joining the Yakima River near the town of Umtanum. While Umtanum Creek itself offers limited paddling opportunities, it plays a key role in the popular recreational floating and paddling section of the Yakima River between Umtanum and Roza.

The Yakima River from Umtanum to Roza is a scenic 10-mile stretch of flatwater to Class I rapids, perfect for beginner paddlers and casual floaters. This section winds through the picturesque Yakima River Canyon, offering stunning views of the arid Eastern Washington landscape. The put-in at Umtanum features a parking lot and pedestrian bridge leading to the launch site. A special parking fee is required here, as the Washington Discover Pass doesn't apply.

For those seeking a slightly longer trip, the Ringer to Roza section extends the float to 10.25 miles. The Ringer put-in is located about 0.35 miles down Ringer Loop Road, accessible via Canyon Road. Both sections end at the Roza take-out, where paddlers will find the Roza Campground.

These Yakima River floats are best enjoyed during the summer months when water levels are stable and temperatures are warm. The trips typically take 3-6 hours, depending on the chosen put-in and water conditions. Kayaks, canoes, tubes, and other small watercraft are all suitable for these gentle stretches.

Wildlife enthusiasts should keep an eye out for bighorn sheep, which are often spotted on the canyon walls. The area is also home to diverse bird species, including golden eagles and ospreys. The surrounding landscape features sagebrush steppe vegetation typical of the region.

For those interested in exploring Umtanum Creek itself, the Umtanum Creek Canyon Trail offers a scenic hiking option. This trail follows the creek through a narrow canyon, showcasing the area's unique geology and ecology.

Safety considerations include wearing appropriate personal flotation devices, being aware of potential wind in the canyon, and carrying sufficient water and sun protection. Paddlers should also be mindful of private property along the riverbanks and respect any posted restrictions.

While single-day trips are most common, the presence of campgrounds like Roza makes multi-day adventures possible for those wanting to extend their time on this beautiful stretch of the Yakima River.
