The Sweetwater River, flowing through southwestern Wyoming, is a relatively remote and scenic waterway. Due to its mountainous source and snowmelt, the river's water tends to be quite cold throughout the year. During the summer months, the water temperature usually hovers around 50–60°F (10–16°C), which can be refreshing for a quick swim or wade, but may feel too cold for extended periods in the water. In the winter, the water temperature can drop significantly, making swimming or wading impractical in most areas.

Swimming in the Sweetwater River is not as common as other outdoor activities, primarily due to its cold temperatures and sometimes swift currents, especially in the upper stretches. The river is more frequently enjoyed for fishing, rafting, and kayaking. Some of the calmer sections of the river may allow for brief dips or wading, particularly in areas where the flow is slower. However, swimmers should always be cautious of the river's varying water levels and potential hazards like debris or strong currents, which can make swimming risky. Overall, while the Sweetwater River offers plenty of opportunities for outdoor recreation, it is best known for its peaceful environment and activities that don't require prolonged exposure to its cold waters.
