Knoll Lake boat ramp provides access to a 75-acre forest lake at 7,300 feet elevation in Coconino National Forest, located approximately 80 miles southeast of Flagstaff via rough graveled forest roads. Only electric motors are permitted on the lake.

The remote location requires traveling 20+ miles on dirt roads (including switchbacks), so arrive prepared with supplies; the campground operates mid-May through mid-September, though winter road closures make access difficult during colder months.
