🍂 Colorado’s Best Late-Season Rafting & Inflatable Kayaking: Where to Go When the Water Drops
Why Late-Season River Trips Are Underrated
Late season — typically August through September (and sometimes early October) — is one of the most comfortable and enjoyable times to be on Colorado rivers.
You can expect:
Warmer water and air temperatures
More predictable flows
Smaller crowds
Longer, relaxed days on the river
While peak runoff delivers big adrenaline, late season delivers comfort, scenery, and versatility, including the perfect conditions for inflatable kayaking.

Why inflatable kayaks shine late season:

Warmer water = more comfort and confidence

On the Roaring Fork and other suitable sections, inflatable kayaking typically runs July through September, offering splashy fun without the intensity of peak runoff.

Half-day trip options
Easy access to Glenwood Springs hot springs afterward

What Happens to High-Adventure Runs Late Season?
Some technical, snowmelt-dependent sections — like Pine Creek (Class V) or the Numbers (Class IV) — typically taper off by mid-August.
When that happens, guides shift focus to:
Consistent, dam-controlled sections
This ensures everyone still has a great river experience, even as conditions change.
Safety & Professional Guidance Matter More Late Season
Lower water doesn’t mean no risk — it just means different risks. Late-season trips still require professional oversight, proper gear, and accurate trip matching.
Reputable outfitters will:
Monitor daily flows using USGS gauges
Adjust trips based on conditions
Match guests to appropriate sections
Provide all necessary gear (PFDs, helmets, wetsuits as needed)
Late season is often the safest and most comfortable time for first-time guests — especially families.
Why Late Season Is a Favorite Among Guides
Ask any seasoned guide, and many will tell you late season is their favorite time to be on the river.
Why?
Relaxed pace
More time for wildlife spotting and storytelling
Beautiful light and fall colors
Happy, comfortable guests
It’s not about chasing the biggest water — it’s about the best overall experience.
