The lower EF NF Trinity is a great class III run that is easily accessed via an easy-to-drive Forest Service road off Highway 299. It usually only runs with winter rains but also spring snowmelt. And, yes that is its name: East Fork North Fork Trinity River...just like that.
The run has a steady pace, great camping options, and awesome water quality. The take-out is at the confluence with the NF Trinity River and there is easy riverside camping here at an old homestead site.
It's possible to link up with the Pigeon Point run on the Trinity River: just keep going past the usual take-out and in about 1-1/2 miles you'll join the Trinity River just upstream of the Pigeon Point Campground put-in.
Always be on the lookout for wood blockages. The 2021 Monument Fire burned through this area and even more large wood will be entering the stream and moving downstream as a result. Additionally, cut logs and trees from the firefighting effort now are in the channel and pose risks to boaters. Contact the Shasta-Trinity National Forest at (530) 623-2121 to voice your concerns over the cut wood in the channel and to report any resulting hazards.
Best Guidebook: The New School Guide to Northern California Whitewater (Dan Menten, 2016), p. 128. He suggests flow estimates of 15% of the NF Trinity gage.
