There are many trails and routes all across
Grand Canyon National Park, but most are concentrated in the developed
South Rim area, and on the less visited
North Rim. The best 20 of these trails which start from the rim are featured here (including Lava Falls Trail in the Tuweep region), most either descending all the way to the Colorado River or leading to viewpoints along the canyon edge.
The best paths are those to the river, and the full hikes tend to need at least one day camping in the canyon - not so many people complete the round trips in one day. All such trails have several intermediate destinations suitable for shorter hikes, though the hike ratings are based on the full distance, and take into account the scenery, solitude and challenge.
