Mile by Mile Guide
Mile 0 |
BEGINNER’S LUCK (IV-V) Put-in (start) O.A.R.S. North Fork Stanislaus Whitewater Rafting trips. Beginner’s Luck is often the most challenging rapid of the day. However, the lower half of the run is extremely thrilling with steep, continuous whitewater. Prior to excessive rainfall in 1997, the action started with Sourgrass Ravine (Class V), however, the North Fork Stan was drastically altered after flooding caused a large landslide. Your California whitewater rafting trip on the North Fork Stanislaus River starts with Beginner’s Luck rapid. This is a staircase-like rapid in which the first drop is followed by a steep ramp and a large hole. The second drop is typically run as far left as possible. However, the choice of routes varies depending on the river’s flow. |

BODY SLAM (IV) There is a technical entrance to this rapid, especially at low water flows. You will make a hard push to the left to avoid a 6-foot wide by 6-foot high pour-over. Go over the top and you get "Body Slammed." |
