Onawa sits strategically positioned about 45 miles north of Omaha and 35 miles south of Sioux City, making it a natural stopping point for RVers traveling the I-29 corridor.

These facilities typically offer standard 3-inch connections for black water dump needs, though amenities like rinse hoses and potable water vary by location.

Traveling to Onawa by RV

Onawa sits right off I-29 at Exit 112, making it incredibly accessible for RVers traveling the major north-south corridor between Kansas City and Sioux City. Highway 175 provides the main route into town from the interstate, and it's designed to handle RV traffic without any concerning restrictions. The road surface is well-maintained year-round, though you'll want to watch for occasional construction delays during summer months.

RV routing through Onawa itself is pretty straightforward thanks to the town's grid layout. Main streets like 10th Street and Iowa Avenue can accommodate larger rigs, but some of the residential side streets get narrow. Most dump stations are located on or near these main thoroughfares, so you won't need to navigate tight residential areas. There's one low railroad bridge on the east side of town that sits at 12'6", so taller RVs should stick to the main routes we've mapped out.

Overnight parking options are limited but workable. The Casey's General Store allows overnight RV parking with permission, and there's a small rest area about 8 miles south on I-29 that works for a quick overnight stop. Walmart parking isn't available since Onawa doesn't have a Walmart, but several campgrounds offer overnight rates if you need hookups. During winter months, be aware that Highway 175 can get icy, and the Iowa DOT sometimes restricts RV traffic during severe weather events. Spring brings the possibility of flooding near the Missouri River, which can affect some back roads but rarely impacts the main dump station access routes.

Some of the private park stations have minimal rinse capabilities, so plan accordingly if you prefer a thorough clean-up. Most stations here accept credit cards, but it's smart to carry cash since a couple still operate on the honor system with drop boxes.
