The trailhead is on the North Rim, about 1.5 miles from the lodge.
Elevation at trailhead is 8,255 feet. The Colorado River is at elevation 2,400 feet. The trail runs 14.6 miles from rim to the river. The trail is in good condition.
Water is available along the trail at Supai Tunnel and Roaring Springs. The stretch from there to Phantom Ranch (next water source) is 8.5 miles. The North Kaibab is longer and more strenuous than the South Rim trails since it climbs over 1,000 feet higher. It's also less traveled for that reason, so you'll enjoy more solitude (in comparison anyway).
There are no technical sections along the trail, but you have to be prepared for hot weather. If you are going up this trail in the summer, you'd better know what you are getting into. Bring lots of water, food, and sun block.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
