An espresso hair run usually combined with the middle and lower narrows. The main rapids are Supercollider and Whiteline, both easily scoutable from the road. At truly high flows, only those with the proper combination of expert skills and excessive foolishness should attempt this section.

Suggested river levels for paddling this section of the Cache La Poudre River are between a bare minimum of 150cfs and a high of 5,000cfs. River conditions sourced from USGS 06752000, the Cache La Poudre R A Mo Of Cn Remember only watercraft are permitted at Upper Narrows.
