Spring River

The Spring River from Mammoth Spring to Hardy is Arkansas’s classic cold, spring-fed float. roughly **nine million gallons per hour** leave Mammoth Spring at about **58°F**, keeping the river runnable and trout-stocked most of the year. Families swim and tube the calm pools; paddlers work Class I, II rapids and short drops (portage High Falls and other ledges in high water).

Public swim/take-out options include **Hardy Beach** below the US 62/167 bridge; put-ins commonly start near Dam #3 south of Mammoth Spring (AR 342 off US 63) or at private campuses such as Many Islands. Water stays cold even in August. PFDs are strongly recommended for floaters and weak swimmers. Hardy’s historic downtown sits minutes from the river, so swim-or-float days pair easily with food and outfitter shuttles without a long shuttle logistics scramble.

Spring River works well as a day trip from Jonesboro or Walnut Ridge. Stock up in town, then head to the water with food, water, and sun protection.
