Killer Fang Falls Put In provides access to the scenic Upper Clackamas River section, located near the Collawash River confluence approximately 23 miles east of Estacada on Highway 224/Forest Service Road 46. This put-in launches paddlers into an 8.

7-mile Class III-IV run featuring dramatic conglomerate boulder formations and forested canyon scenery, though paddlers should be aware of significant hazards including the notorious Class VI Killer Fang rapid and The Sieve, which require portaging or expert navigation.

The area is relatively remote with limited development; paddlers typically begin with a mile of flat water before rapids gradually increase in intensity.
