RV travelers pulling off Interstate 90 will find Oasis Campground positioned directly adjacent to the highway in Oacoma, with sites accommodating rigs up to 65 feet. The campground operates with full hookups including electric, water, and sewer connections, plus amenities like showers, laundry facilities, and a swimming pool that stays open late for arriving travelers.
Sites feature level parking on grass with generous spacing, though campers note spots 73-75 sit particularly close to rental cabins. The shower facilities earn consistent praise from visitors, with Maureen M. highlighting "very clean restrooms and showers and lots of stalls." A basketball court and playground occupy the grounds, while the Missouri River sits within biking distance for those seeking water access.
The interstate location creates constant highway noise that some find disruptive for sleeping. WiFi service proves unreliable in many sites, though cellular coverage generally works well. Walking access to convenience stores, restaurants, and a casino provides dining options without driving.
The campground functions primarily as an overnight stop for cross-country travelers rather than a destination stay. Sites can be reserved in advance, and the drop-box system allows late arrivals when the office closes.
