Onion Creek is a tributary of the Colorado River located near Moab, Utah. This small but scenic waterway originates in the La Sal Mountains and flows northwest, eventually joining the Colorado River about 20 miles northeast of Moab. While Onion Creek itself offers limited paddling opportunities, it plays a significant role in the popular Moab Daily section of the Colorado River. The Moab Daily run on the Colorado River, which incorporates Onion Creek, is an 18-mile stretch from Dewey Bridge to Sandy Beach. This section is renowned for its accessibility and suitability for beginners and families, featuring Class II-III rapids interspersed with calm water. The run can be divided into shorter segments, with Onion Creek serving as a notable access point and landmark.

Paddlers typically encounter six main rapids along the Moab Daily, including the Onion Creek Rapid, which occurs shortly after passing the Onion Creek confluence. This rapid is generally considered straightforward, with the easiest line on the left. The overall difficulty of the run ranges from Class I to III, making it ideal for novice rafters and kayakers while still offering excitement for more experienced paddlers.

The best time to paddle this section is from spring through fall, with peak flows occurring in late May to early June during snowmelt. Summer months provide warm water and consistent flows, though afternoon thunderstorms can be a concern.

The surrounding landscape is characterized by towering red rock formations, including the iconic Fisher Towers visible from the river. Cottonwood trees line the banks, providing habitat for various bird species and occasional sightings of desert bighorn sheep.

Key access points include Dewey Bridge (put-in), Hittle Bottom, Onion Creek, Rocky Rapid, and Sandy Beach (take-out). The town of Moab serves as the primary hub for river activities, located about 30 minutes from most access points.

For those seeking multi-day adventures, numerous campsites dot the riverbanks, including a large beach campsite 1.4 miles downstream from Dewey Bridge. Overnight trips allow paddlers to fully immerse themselves in the stunning canyon scenery and starry desert nights.

Safety considerations include proper sun protection, staying hydrated in the arid climate, and being prepared for rapid weather changes. While no permit is required for private trips on this section, adhering to Leave No Trace principles is crucial for preserving the area's natural beauty.

The Moab Daily section, including Onion Creek, offers a perfect blend of scenic float and mild whitewater, making it one of Utah's most popular river experiences for both locals and visitors alike.
