Cycling Kyle Canyon a top Nevada and US bike climb.
21.6 miles gaining 5,357’ to 8,112’ at 4.7% average grade.
The first 9 miles of the Kyle Canyon climb are in a somewhat bleak high desert environment. At around 9 miles we begin to enter a canyon-like setting with more interesting views and rock formations. We enter Spring Mountain National Recreation Area at mile 12.2 and reach the turnoff to Hwy 158 at mile 17.5 (3,986' climbed at 4.6% average grade to this point). The final 4 miles up Hwy 158 are at 5.8% climbing 1,325' with some very good views of the Kyle and Red Rock Canyon National Conservation Area to the southeast.
Finish on Hwy 158 at 8,112’
Steepest ¼ mile begins at mile 20.5 (7.8%); steepest mile begins at mile 20.2 (7.2%)
This climb can be extremely hot and probably should be avoided between June and August when the average high temperatures range from 99 to 104.
This US #49 bike climb can be done in conjunction with 3 other Top 100 U.S. Climbs in the immediate area: #24 Hwy 156 (Lee Canyon) (which shares its first 14 miles with #34 Hwy 156/158), and Hwy #70 Hwy 157 (Mt. Charleston), which shares its first 17.5 miles with this, the Kyle Canyon climb. Be cautious if doing this ride group without support as the only provisions are likely to be at the Mt Charleston Lodge at the end of Hwy 157 - support is highly recommended for any effort involving Lee and Kyle Canyons in the same ride. Undertaking these 4 climbs in one day is about 90 miles of riding and 12,000' of climbing, but you can actually fly into Las Vegas very early and get er done that day, if you really want to punish yourself - as we did!
Wipe that smile off your face! This is only #1 of 4 . . .
