After driving over the worst surface imaginable the canyon opens up out of nowhere. Standing on the edge of the canyon near the highest lookout hut, the trail is easy to spot.
A good spring shower over snow pack really gets the Little Colorado River running full throttle. The hike down is short lived and somewhat uneventful. There is little growth in the area. Be careful as the trail is steep and slippery in areas.
The safest option is to hike when the trail is dry. Then again, it's likely you won't want to be here during a dry spell! If spring rains are in full force prepare for a mini Niagara Falls in the middle of nowhere!

As of 2017 Leupp Chapter where the falls reside say you do not need a permit. Navajo Nation says "Grand Falls area also requires you to have a backcountry permit and is a day use area."
