Floating the Warm Slough

People wait all year for the weather to warm up in Rexburg to float the river and the Warm Slough is the perfect place! Just as the name implies, the water is actually warm and has a slow, gentle current. The float can take around 45 minutes to 1.5 hours, depending on the speed of the current. The river has a few curves and, at the end, it almost makes a ‘U’.


You can park two cars at each end of the river (The end point is about a mile down from the starting point). The starting point is a ten to fifteen-minute walk from the end. If you prefer, you can just park at the starting point and walk back after floating the river.

You will see a sandy area where you get out of the Slough. At times during the summer, the water gets shallow enough that you may have to get up and walk, but by mid-summer, the water level should be high enough that you shouldn’t have to. The area has a few campsites with restrooms and fire pits.
