Campgrounds and RV parks near Onida, SD

Onida sits in Sully County on the rolling plains of central South Dakota, about a half-hour drive from the Missouri River and Lake Oahe. Lake Oahe is a large reservoir formed by Oahe Dam, a U.S. Army Corps of Engineers project on the Missouri River just north of Pierre. Construction on the dam began in 1948, and it started generating electricity in 1962. The reservoir stretches roughly 231 miles from central South Dakota into North Dakota and is one of the largest constructed reservoirs in the country. Most RV-friendly campgrounds near Onida cluster along Lake Oahe to the northwest and along Lake Sharpe, the reservoir below the Oahe Dam, to the south near Pierre. Private resorts such as South Whitlock Resort and Bob's Resort Inc sit on the shoreline north of town, while South Dakota Game, Fish and Parks operates West Whitlock Recreation Area, Main - Farm Island State Recreation Area, and Oahe Downstream South within an easy drive. The area draws anglers, boaters, and hunters more than sightseers. Expect wide-open prairie, big skies, and quiet, small-town services in Onida itself, with fuel, groceries, and marine supplies more readily available in Pierre.

South Dakota Game, Fish and Parks manages the state recreation areas in this area, including West Whitlock Recreation Area, Main - Farm Island State Recreation Area, and Oahe Downstream South.
