When Does Whitewater Rafting Season Start?

Whitewater rafting season varies depending on the river, water levels, and snowmelt. For the Lower Kern River, where Whitewater Voyages operates, the season typically begins in early April and runs through September, with the peak flows occurring in May and June.


However, the Upper Kern is a different beast. This section is fed purely by Mother Nature, meaning that it’s only available for a limited time each year, usually from early May to mid-June. If you’re looking for relentless, fast-moving whitewater, this is your golden window.

Why the Upper Kern is a Must-Do – But Hurry!

The Upper Kern is one of the most electrifying whitewater runs in California - but it’s fleeting. Since it’s entirely snowmelt-dependent, its season is short-lived, typically lasting only 6–8 weeks.


Here’s why you should prioritize it:


  • Non-Stop Rapids: Unlike dam-controlled rivers, the Upper Kern runs wild with consistent, high-energy whitewater.
  • Limited Availability: When the snowpack runs out, it’s gone for the year.
  • Pure Adrenaline: If you crave fast-moving, technical whitewater, this is the ride of a lifetime.


If you’ve been eyeing the Thunder Run or the Forks of the Kern, don’t wait. Spots fill up fast, and when the season’s over, it’s over.
