Thunder River Trail

This trail is considered difficult and strenuous, often described as a 'death march' due to significant elevation changes. You'll encounter steep descents with switchbacks, loose and rocky sections, and areas of slickrock. The path plunges through various geological formations, and some stretches can be rough, exposed, and have narrow ledges. Routefinding can also be challenging in places, relying on cairns for navigation.

The Thunder River Trail is typically accessed from the North Rim of Grand Canyon National Park.
