This extremely steep road is typically seasonally closed due to snow until late April or early May, but, if the road is open, prepare for a brutal challenge. The climb gains around 1,500-2,000 ft in just 2.5 to 3.3 miles, resulting in an incredibly steep average gradient likely between 11% and 13%. You will face relentless pitches well over 15%, potentially hitting 20%, demanding your absolute lowest climbing gears and maximum physical effort. As you grind your way up the narrow, winding paved road with its tight switchbacks, you'll experience unique, dramatic views from within the canyon walls.
