Tuolumne River rafting trips are know for numerous rapids, remote camping and pristine water. Whitewater rafting and kayaking is possible all summer which makes it an ideal destination for Bay Area boaters as well as tourists heading to Yosemite. Floating the Tuolumne River is best in late April and May. The water is consistently fun without being scary and the hillsides are green with wildflowers. Due to it’s unique attributes the Tuolumne received Wild and Scenic River status in 1984.

While spring is the optimal time to raft the Tuolumne, the river has something for everyone depending on the season. Looking for big huge waves check out the river in early June when it is running between 5000 and 10000 cfs. You might also want to check out the South Fork of the Tuolumne in the spring. Want a relaxing trip with hikes to grottoes and swimming holes up side canyons, try a 3-day trip in late July or August. A two-day trip on the Tuolumne River provides great rapids each day along with an opportunity to sleep down in the canyon and do some exploring. Want big technical Class V later in the summer try the Upper Tuolumne / Cherry Creek. It is worth an extra day to float the placid waters of the Merced River through Yosemite Valley.

One important note is that summer releases are typically only 3 hours which means boaters have to keep moving downstream to insure they don’t get behind the “bubble” of water. Water typically gets to put-in about 10 am.

Tuolumne River Itinerary:

Put-in at the boat ramp at Meral’s Pool. Be sure to be efficient at the boat ramp because only one vehicle can use it at a time. This is also the take-out for the upstream class V whitewater run on the Upper Tuolumne, also known as Cherry Creek.
Mile 0: Meral’s Pool Put-in and Rock Garden Rapid (IV)

At low water Rock Garden is an excellent test for boaters to see if they are ready for the Tuolumne River. The next rapid right around the corner, Nemesis (mile: 0.4) is just as challenging at low water.

Mile 0.75: Sunderland’s Chute (IV)

Sunderland’s has a tricky entrance followed by some big features farther down the rapid that typically flip boats right to left. At most flows there is not time to recover before the next rapid Hackamack’s Hole (mile: 1.0) which also has big features a higher water.

Mile 1.5: Ramshead (IV+)

Above 4500 cfs this rapid gets pretty tricky as the water at the bottom all pushes to left into a boat flipping hole.

Mile 1.9: India Rapid (III+)

India is named after the first woman, India Fleming, who kayaked the river in July, 1969. Right after India Rapid at mile 2.1 is Phil’s Folly (IV+) which always has a tricky exit and is arguably the hardest rapid on the river at 10,000 cfs. Below Phil’s the river mellows out for a few miles. There is a nice place to pull over on river left at Tin Can Cabin (mile: 3.3) for lunch or to camp.

Mile 4.5: Sterns Rapid (IV)

The rapids start to build again just upstream with a couple class III rapids Screaming Right Hand Bend (mile: 4.1) and then Zach’s Falls (mile: 4.3) which lead to Sterns. There are 3 chutes at Sterns, none are very clean. Most boats that flip first get bridged in the left chute.

Mile 4.8: Evangelist (IV)

Evangelist is always a fun rapid. At low water there is a tight line between car sized rocks. As the flow increases they form two holes and there is still a line between the holes.

Mile 5.1: Frame Crusher (III+)

This is another fun rapid with a ledge on the bottom right. At high water (6000+) be careful of the sleeper hole downstream from here on river left.

Mile 5.6 Clavey Falls (V-)

Clavey Falls was the original class V rapid in the late 1960’s. Today people are pushing the limits of class V to a much higher level but this is still a challenging rapid particularly between 6000 and 8000 cfs. The Clavey River also flows in here on river right. There are nice campsites on both sides of the river above the rapid along with spectacular hiking and swimming up the Clavey. There are Class IV-V and Class V+ sections on the Clavey.

Mile 7.0: Little Niagra (IV)

A challenging boulder garden with a couple of great opportunities to wrap.

Mile 7: Powerhouse (II)

Powerhouse rapid has some fun waves at highwater. It is also nice camping spot on river right. The Powerhouse was built in the early 1900’s to provide power to the near by mines and Groveland. There is more camping the next few miles downstream. On river right there is camping and hiking at Grapevine Creek (mile 7.8). A little farther downstream is a large campsite downstream across from Indian Creek (mile 8.0).

Mile 9.5: Grey’s Grindstone (IV)

This is longest rapid on the river. There is a tricky entrance then some fun boulder dodging in the middle and finishing with some waves at the bottom of the rapid.

Mile 10.8: Surf City (III)

Some fun surfing here at low water and fun waves at all flows.

Mile 11.4: Driftwood Paradise (III)

Just upstream of the rapid on the left are two nice sandy beaches for camping at low water. The rapid has some big rocks that need to be avoided. Luckily the current isn’t to fast so there is time to work right through the rocks.

Mile 12.6: Cabin (IV)

Cabin rapid has a big rock in the middle of the rapid that forms a pour-over at higher water. At the bend to the right Big Creek flows in on the left making a nice little hike in the spring when it flows.

Mile 12.8: Hell’s Kitchen (IV+)

Below Big Creek the river enters Hell’s kitchen with a long splashy entrance followed by some narrow routes through big rocks at the bottom.

Mile 13.5: Playground (III)

Fun boulder dodging at low water which becomes hole dodging at high water. The rapid ends at the Mohican Mines where there is a campsite on river left. Just downstream at mile 15.1 the North Fork of the Tuolumne enters offering more camping and a fun side hike.

Mile 15.1: North Fork Tuolumne River

On river right, the North Fork of the Tuolumne River enters. The river is usually low enough to hike up to some nice swimming holes. During high water years there is a Class IV+ run down the North Fork.

Mile 16.5 – 17.7: the Alps, Let’s Make a Deal and Pinball

Many times these rapids are under water when the reservoir is high. When they are out Pinball, the last one, is challenging.

Mile 18.0: Take out – Ward’s Ferry
Don Pedro Reservoir is in the process of improving the take-out. At the moment the take out is the most challenging part of the trip particularly when the reservoir is low.
