The river slips past sagebrush and pine as you push off from the AVA Rafting launch on Park Avenue — a flat-stretched wake interrupted by the short, punchy riffles of Little Gore Canyon. Paddleboard under a wide Colorado sky, feel the current tease your board at the riffles and then ease into long, reflective pools where sun-warmed gravel bars invite a swim or a slow stretch.

The river slips past sagebrush and pine as you push off from the AVA Rafting launch on Park Avenue — a flat-stretched wake interrupted by the short, punchy riffles of Little Gore Canyon. Paddleboard under a wide Colorado sky, feel the current tease your board at the riffles and then ease into long, reflective pools where sun-warmed gravel bars invite a swim or a slow stretch.
This stretch of the Upper Colorado is carved from uplifted Uinta and Gore Range bedrock; seasonal snowmelt drives lively Class II riffles that are ideal for learning balance while still delivering an adrenaline pulse. Kremmling grew as a ranching and railroad hub, and the river remains a working landscape for anglers, outfitters and local wildlife — bald eagles hover, mule deer browse the cottonwood margins.
Expect a hands-on, half-day outing: instruction, a fitted PFD and optional wetsuit, then a guided run downstream with chances to switch to kneeling or sit in an inflatable kayak. The route favors approachable skills over technical whitewater, but wind and flow change the game quickly, so timing matters.
Practical notes: wear secure footwear, layer for variable spring and fall water temps, and bring water and snacks in a dry bag. Pace yourself through the riffles — plant your paddle, lean into the turn, and use eddies to rest. Leave no trace: pack out sunscreen bottles and food wrappers, and rinse gear to avoid transporting aquatic invasive species. In four hours you'll get paddle time, a swim, and a clear sense of how the Upper Colorado challenges and rewards equally.
