Spring River
Float Trip Guide.
Visit the big spring on land, then choose your paddle downstream. The Arkansas Spring River changes character between Mammoth Spring and Hardy; the name alone doesn’t describe the trip.
Today on the Spring River
Eddy reads the gauge, the trend, and the forecast and writes a fresh take a few times a day. Use it as one input alongside your own judgment, the outfitter you’re renting from, and current advisories from the agency that manages your stretch.
Why the Spring River is different
The Arkansas Spring River begins with a spring worth seeing before you ever unload a boat. Mammoth Spring State Park makes a memorable stop, and the cold water flowing out of that area sets the tone downstream. Around Hardy, the river has a long-established floating identity, but its different reaches deserve different plans.
Do not mistake steady spring inflow for an effortless float. The upper river includes dams and ledges, while the water below Hardy has its own current and access pattern. This guide’s featured outing begins below Hardy; the park visit at Mammoth Spring is a separate stop, not a suggestion to launch through the dam.
- Mammoth Spring State Park adds an easy focal point for the weekend, even if you float farther downstream.
