A cold, clear, spring-fed float in north-central Arkansas, rising at Mammoth Spring and running past Hardy toward the Black River. Reliable year-round flow, trout in the upper reach and smallmouth below, and a few lively ledges like Saddler Falls.

Pick a put-in and take-out and we'll estimate float time, mileage, and shuttle — then give you a link to share with your crew.

The Spring River has two significant ledges—Saddler Falls and High Falls—that should be scouted and can be dangerous at higher flows or for less-experienced paddlers. Portage if in any doubt.
