Distance and hiking times vary. This is the only maintained trail into the canyon from the North Rim. Even a short hike to Coconino Overlook (1.5 miles / 2.4 km round-trip) or Supai Tunnel (4 miles / 6.5 km round-trip) can give you an appreciation for the canyon's rich natural beauty and immense size. A hike to Roaring Springs and back is extremely strenuous and takes a full day (7-8 hours) - begin your hike before 7 a.m. Roaring Springs lies 3,050 feet / 930 m below the canyon rim and is 9.4 miles / 15 km round-trip. A day hike beyond Roaring Springs is not recommended. Many years of experience have shown that hikers who proceed beyond this point during the hottest parts of the day have a much greater probability of suffering from heat-related illness, injury, or death. This trail is also used by mules. NOTE: Round trip to the Colorado River is 28 miles / 45 km and trail descends almost 6,000 ft. / 1,800 m. Under no circumstances should you attempt to hike from the rim to the river and back in one day! Do not hike during the hottest part of the day.
