Once things get up to 80-100 cms this run is starting to feel like a big river and the biggest rapids are certainly IV+. At 150 cms the river is pushy big water class IV-V - it is classic kayaking at these levels. Anything over 200 cms is generally described as terrifying in a few spots, but still doable for strong boaters. Make your own mind up about whether boating Fear Canyon at these or higher levels is worth it for you. It's been done successfully at at least 350 cms.

Access to Fear Canyon is along well travelled and well maintained dirt logging roads. Expect about a 1 hour drive from town to the river. From Squamish drive up the Squamish River - pass the Ashlu turn off and keep driving. You will eventually reach the Elaho-Squamish confluence. Stay left to head up the Elaho. The take out is at the first bridge that crosses the river - there is easy access just downstream of the bridge at the put in for the Elaho-Squamish raft run (near the gauge station). Drive upstream on river left - you can put in near where a small waterfall (it's obvious) goes under the road or you can continue up to the next bridge, though this usually means a portage (or sneak lines at high water) around 2 rapids just above the small waterfall.
