This trail start either at the North Kaibab Trailhead or at the Parking area for the North Rim Visitor/Lodge area. There is a drinking fountain to the east of the trailhead if water is needed. The parking area at this end is small and during sometimes maybe full. Make sure you follow the parking signs so you won't be towed away. It is the final 1.75 miles after some of the people that do the Rim to Rim have to go before they have the relief of the accommodations at the North Rim.
The trail if you start at the Kaibab Trailhead starts to the west of the trail sign and immediately goes up in a steep straight up ramp like trail. You crest this area and then cross the road to the other side. Here is the housing for the people that work on the north rim during the summer months. Across the street a little ways up is the new fire station and buildings where they store and base the summer fire crew. You pass the Back Country Headquarters on the way. You follow along the road on the west side and about the 1 mile mark is the campground general store. Here if you have hiked from the other rim you can stop and get supplies. They have food and other supplies even cold drinks. There is a pay phone here and wifi on the porch of the lodge to phone whom ever you need to. The cell phone coverage as of this writing is spotty on the north rim. Continue down he path next to the road. There are picnic tables in a couple of spots along the way if you need a place to rest. You will need to cross to the other side of he road when you get to the hotel portion of the North Rim Lodge. There the trail follows along the parking lot with views of the Roaring Springs Canyon. It ends/starts there at the parking area.
