9- Truckee River
While this part of the Sierra Nevada is typically known for some of the world’s best whitewater, well, you’ve seen the news: there’s not exactly a ton of snow-melt cascading down the mountains right now. But fear not, the Truckee remains a fun time; its calm waters now lend themselves to a relaxing day-long booze cruise where slow-moving boats will just as soon invite you on board for a beer as they will spray you with a squirt gun when you float by.
8- Ichetucknee River
Fort White, Florida
You’ll find this river in the popular Ichetucknee Springs State Park. Float and drink for an hour and a half in the 72-degree water beneath a canopy of shady oak trees. If you want more fun, then climb one of the oak trees and jump in. The swim back to the bank is easy.
