Grand Canyon National Park: Thunder River-Deer Creek Loop

This 21.5-mile clockwise loop in Grand Canyon National Park strings together faint trails and an Eden of waterfalls and swimming holes.

You’ll pass one of the nation’s steepest rivers, the Grand Canyon’s slimmest narrows, and some of the Desert Southwest’s biggest waterfalls and most inviting swimming holes. This could also very well be the toughest long-weekend hike in Grand Canyon National Park, but you won’t regret a single sunny mile.
Depart from the Bill Hall trailhead in the cooler late afternoon and climb to 7,166-foot Monument Point for a 20-mile view of redrock cliffs, temples, and buttes. The next 2.5 miles nosedives nearly 2,000 feet to the Thunder River Trail. Turn left and cache water for the return trip (in four days). Hike for two more miles and camp near the mushroom-shaped rocks on the Esplanade.
On day two, you’ll crest the Redwall to see the serpentine guts of the lower canyon. Descend the loose Thunder River Trail into sun-scorched Surprise Valley. Follow cairns south to the dry forks of Bonita Creek, then at milepoint 6.4 swing east toward Thunder River. Swim, nap, and eat at the multitiered falls of Thunder River (the world’s shortest named river). To finish the seven-mile day, zigzag along Tapeats Creek to its lower designated campsite near the Colorado River.
Day three: Leave established trail and follow a faint path northwest along the Colorado. The undulating route goes from beach to cliffbands, crosses Bonita Creek (dry), and offers bird’s-eye views of rafters paddling 135 Mile Rapids and Granite Narrows. Camp three is under cottonwoods at Deer Creek, three hard-earned miles from Lower Tapeats. Nearby is the cliff-pinched Patio (primo dinner site), a cherry-picker view of the Colorado, and the 180-foot Deer Creek Falls (best swimming hole).
The next day, spend a few hours exploring Deer Creek’s narrow gorge, tank up on water, then depart late-afternoon via Deer Creek and Thunder River Trails to a dry campsite on the Esplanade. It’s a four-hour climb to the North Rim on the final day.
PERMITS: Required backcountry permits cost $10 per group, plus a $5 charge per person per day. Apply up to four months before desired departure date. Download form at
WHEN TO GO: Spring, when water is more plentiful, or fall, with mild weather. Avoid summer, when temps soar well above 100°F in the lower canyon.
