Cannonball Run: Rafting Clear Creek Where Gold Rush Grit Meets Whitewater Thrill
Three hours on Clear Creek where technical rapids, gold-rush history, and local flavor meet
The canyon narrows like a clenched jaw and the river—dark, cold, and impatient—starts to speak in staccato. You strap on a helmet, slide into the rubber bloom of the raft, and feel the current's first meaningful tug: the river daring you to keep pace. For the next three hours Clear Creek will push and test you, threading through gulches scarred by mining relics while pine-scented air slashes the heat off your face. This is the Cannonball Run—an intermediate whitewater stretch outside Idaho Springs, Colorado—where adrenaline and regional history collide.
Trail Wisdom
Wear water shoes
Stony riverbanks and rocky put-ins demand closed-toe, quick-drying footwear for traction and protection.
Hydrate before you go
Cold water masks exertion; drink water before launch and carry a small bottle on the bus to refill afterwards.
Listen to your guide
Clear, practiced commands and quick maneuvers are critical; follow them for safety and better lines.
Protect your skin
High-elevation sun is strong even on cloudy days—apply reef-safe sunscreen and wear UV-protective layers.

Seasonal Guide
spring
Best for: Big water flows, Technical rapid practice, Less crowded runs
Challenges: Cold water temperatures, Fast, more technical rapids, Unpredictable weather
Spring runoff sends higher flows and more challenging hydraulics—great for experienced paddlers but colder and less forgiving.
summer
Best for: Warmest air temps, Stable river access, Beginner-friendly runs at lower flows
Challenges: Higher crowds, Lower water can make sections rockier, Parking congestion near launch
Summer is the most popular season: warmer air, still-challenging rapids, and reliable guide operations.
fall
Best for: Crisp air and foliage, Smaller groups, Photogenic canyon light
Challenges: Cooling water temps, Shorter daylight hours, Operators may reduce runs
Fall offers quieter runs and great light, but colder water and fewer commercial trips as season winds down.
winter
Best for: Viewing frozen canyon features, Off-season photography, Nearby snow activities
Challenges: Commercial rafting largely unavailable, Icy roads and trailheads, Very cold conditions
Winter typically shuts down rafting; the canyon becomes a stark, snowy landscape better suited to sightseeing than paddling.
