Sioux Falls KOA lies just inside the city limits of South Dakota's largest city, but you wouldn't know it from the lush grass campsites. This big-rig friendly campground offers a swimming pool, basketball court, mini golf, fun-bikes, a pavilion for gatherings, a deluxe laundry facility, a game room and a children's play area to keep everyone entertained. You'll find an RV service center right next door. This pet-friendly KOA also offers a Kamp K9 park. You're only 10 minutes from the city's namesake waterfalls. Browse the nearby historic down-town shopping district for specialty items, including Native American art. At the Great Plains Zoo & Delbridge Museum of Natural History, kids giggle at critters from A to Z. Cool off on hot summer days with a float down the lazy river or plunge down the drop slide at Wild Water West Waterpark, about 20 minutes away. Pool: Memorial Weekend - Labor Day Weekend. Max pull thru: 100 feet.
