Family and friends can watch the swim from the shore. There are also visitor parking areas along the dam.
Swimmers are required to use the designated swimmer parking lot and take the free shuttle bus into the start area. Information about the swimmer parking lot will be distributed on our Facebook page and via email prior to the event. A one-day park pass is required to park in the swim beach parking lot, and will be sold on-site by the park concessionaire, separate from the event registration, for event volunteers and the public.
There are accommodations throughout the Black Hills. You can stay on-site at the Pactola Reservoir Campground — find more information about camping at Pactola here.
