Lakes

On South Dakota’s lakes, water-skiers cut over the surface, sails lean with the wind, and boats glide under open skies. If you’d rather reel in a catch, Lake Oahe and Lake Francis Case stretch along the Missouri River with miles of fishing spots for casting out. At Lewis and Clark Lake, pontoon boaters cruise on as the sun dips low while paddleboarders put in steady strokes along the shoreline. For more ways to get out on the water, head to Pactola Reservoir and Sylvan Lake in the Black Hills, as well as Lake Thompson and Pickerel Lake in the Glacial Lakes & Prairies.

Rivers

The Missouri River, one of South Dakota’s Great 8, runs across the state with smaller scenic waterways branching off it. Along the way, it widens into large reservoirs with quieter inlets throughout, leaving plenty of ways to play on the water. On clear streams like Spearfish Creek, fly-fishing keeps you focused on your line for a sudden tug from pink-streaked rainbow trout, and the Big Sioux River holds shimmering walleye and northern pike just below its surface.

Natural Hot Springs

South Dakota’s water activities don’t stop at lakes and rivers — they extend to places like Hot Springs. The city is known for its mineral spas, where natural springs feed waters of varying temperatures, so you can find an option to hit your heat sweet spot. At Evans Plunge, find opportunities for both play and relaxation via slippery waterslides and steamy saunas at the Black Hills’ oldest attraction. 

At Moccasin Springs, it’s a bit like Goldilocks — finding the temperature that feels just right as you soak in outdoor pools ranging from 98 to 105 degrees. Here, the setting feels more like a retreat, with its warm water, surrounding bubblegum-pink hibiscus, and quiet corners that make you forget what day it is.

Water Parks

Swimsuit on, and it’s off to South Dakota’s water parks you go! Race down the slides or float along the lazy river, with summer notes of chlorine in the air as laughter echoes across the park and water rushes nearby. Open year-round, WaTiki® Indoor Waterpark Resort radiates tropical vibes, as flumes curve past palm trees, tubes drift along the river, and a full-service bar sits just steps from the water. Over at Wild Water West Waterpark, everything plays out under the sun, with waves rolling through the pool, rides twisting and dropping, and a 1,000-gallon bucket tipping overhead, sending cold water crashing down upon giddy children.
