Like Gallagher, whitewater rafting thrills adventure seekers, gets people wet, and has resulted in a multitude of copycat amusement park rides. Enjoy the thrill of getting splashed with today's Groupon: for $75, you get a self-guided, three-to-five-hour scenic float on the Stanislaus River for up to six people from River Journey, valid Sunday–Friday (up to a $150 value, including government river use fee).

Fully seasoned paddlers and raw oar-shovers embark on a nature-bound, self-guided adventure on the stately Stanislaus River with River Journey rafting. The Knights Ferry Raft Rental Trip departs daily from Knights Ferry about a two-hour drive from San Jose and Yosemite National Park. The trip begins with an extensive safety talk—the river is rated Class II, meaning certain areas foster a friendly float, but others, such as the Russian Rapid, give riders a controlled rush, much like drinking a Slurpee one gulp at a time while surfing. Rafters can find themselves awestruck by the spectacular scenery and wildlife, possibly spotting beavers, deer, and hawks, all waiting to be discovered by water-bound paparazzi. Sweat-drenched paddlers refresh their soul sacks with a dip in the river or self-brought savory snacks during short stops. During busy weekends, a photographer is on hand to capture all the spray-soaked smiles during this stretch of rafting. At journey's end, a shuttle bus will transport rafters back to their cars.

Check-in time is 10 a.m., and harpoons are forbidden, so packing a midday meal and non-glass-contained beverages is recommended. One medium sized cooler is allowed to ride on the rafts, and the trips leave from different locations on weekdays and weekends, so check their directions page before setting out.

Though River Journey sometimes features discounted prices online, this Groupon still offers the best deal available.
