For the full loop, be prepared for a strenuous workout.
The trail offers varied terrain, generally following the Snake River. You'll encounter primitive paths winding through sagebrush and boulder fields, with towering canyon walls as a backdrop. Some sections may include massive boulders and wild grass, remnants of the Bonneville Flood. Keep an eye out for ancient petroglyphs along the river.

You might also find remnants of the Oregon National Historic Trail.
