Nestled in a high‑elevation canyon within Calaveras Big Trees State Park, this thrilling Class IV+ run beckons experienced paddlers looking for technical, adrenaline-packed fun.
A steep 5‑mile stretch with technical Class IV rapids and multiple Class IV+ drops
Paddle through pristine alpine forest amid wild spring scenery
As we’re one of the only outfitters permitted on this river, you’ll have it nearly all to yourself
Runs during a short spring window - don’t miss your chance to catch it
The North Fork Stanislaus delivers a high‑octane day of alpine whitewater that feels remote and rugged - yet remains easily accessible from the Bay Area and Sacramento.
Less than a minute from put-in, you'll crash through Class IV Beginner's Luck which is an immense staircase of drops, descending a total of 15-feet. After that wake-up call, the whitewater keeps coming in tight chutes and boulder-choked passageways like The Claw and Wallet Slot.
When the mood strikes, we'll stop for lunch on a forested riverside bank. Back on the water, there are still many Class III-IV challenges waiting downstream. The final rapid is Sequoia Sluice, and because it's one of the biggest rapids, it serves as an appropriate climax to an intense day of rafting.
The itinerary above may be altered due to a range of variables, including river flow levels, time of year, and other factors. Contact us if you have any questions.

9:00 am for most trips
All-Outdoors North Fork Stanislaus trips usually start at 9:00 am, but keep in mind that meet times may vary. Please refer to the information sent to you in your Trip Confirmation email, check with your group’s organizer, or contact our office. Plan to be on time; guests that arrive late may miss their trip.
From Hwy 99 near Stockton:
Take Hwy-4 East. Stay on Hwy-4 East for 46 miles. Once you reach the Hwy 49 intersection, continue straight on the Hwy-4 East Bypass to avoid going into downtown Angels Camp. Continue on Hwy-4 East until you reach the Calaveras State Park entrance on the right side.
After passing through the entrance toll booth, continue straight on Big Trees Parkway. Travel 20 minutes on the windy road downhill toward the river. Once you get to the bridge crossing the North Fork Stanislaus River, turn right to the Stanislaus River Access - Day Use lot on the north side of the river. Do not drive across the bridge! Look for the All-Outdoors guides and vehicles.
We encourage you to print and use our driving directions and not rely strictly on GPS navigation. GPS / cellular service is limited to nonexistent in outlying areas.
Knowing what to wear, what to bring, and what's provided makes trip planning smooth and easy. Find all the essential details for a comfortable and well-prepared experience on the river.
What to Wear & BringAll-Outdoors runs paddle raft trips on the North Stanislaus. In a paddle raft, each guest and a professional guide have a paddle and navigate the river working as a coordinated team. North Stanislaus trips are intense and highly participatory so guests need to be ready and willing to paddle. In times of extreme high water, we may elect to use oar-paddle combination rafts (a professional guide steers the boat with oars while simultaneously calling commands to paddlers in the boat). All guests should be able to swim.
The North Stanislaus' steep gradient (70' per mile) creates many stair-stepping drops and tumultuous twists and turns. You'll become an expert paddler, maneuvering through the river's speeding currents and tight chutes. And because All-Outdoors is one of the few outfitters permitted by the USFS to offer trips on the North Stanislaus, you will most likely have the river to yourself.
Immense and peaceful pine forests; crystal-clear water
The North Stanislaus canyon is part of what makes this trip one of our most unique. It begins at a high elevation--over 4000-feet in Stanislaus National Forest amidst towering pine and fir trees. The waterway itself is narrow and small, instilling the feel of an intimate mountain stream. Dogwood and wild azalea pepper the riverbanks. Halfway down this intense run we enter Calaveras Big Trees State Park which is home to the largest living trees on earth, the Giant Sequoia Redwoods.
The North Stanislaus is an early springtime river. Even though there is one dam above this run, the river depends on snowmelt below the dam for its flows. The North Stanislaus begins to run when the snow below 6,000' begins to melt after winter. Flows are usually best from early or mid-April to mid-May. Even though its season is limited to just four to six weeks, avid rafters should make every effort to experience this unique run at least once.
* Season length, river flows, and days of water releases may vary. For this year's flow predictions and real-time water levels go to the River Flows page.
We provide a gourmet "build-your-own" sandwich lunch that includes all the fixings you’ll need to assemble the perfect sandwich along with kettle style potato chips, dried fruit, and chocolate. Enjoy your relaxing, riverside meal before heading back out on the water for more adventure.
If you have special dietary requirements, we encourage you to tell us at the time of your reservation so we can discuss options.
