The Ledges River Run in Colorado is a thrilling class III+ river run with a few challenging obstacles. The run starts with a calm stretch, followed by a narrow and bumpy section called "Little Niagara." The river then flows through a series of ledges, creating exhilarating drops and rapids. The most challenging section is the "S-Turn," which requires precise maneuvering to avoid rocks and navigate through a narrow channel. The best time to float this section is during spring and early summer when water levels are higher, with recommended CFS of 500-1000. Overall, the Ledges River Run is perfect for intermediate-level rafters looking for an exciting adventure.
