Why this is the best time to do the Grand Canyon's best hikes

That's because Grand Canyon National Park receives most of its 5 million annual visitors in the scorching summer months.

And with fewer people.

Here are six of the best trails in the Grand Canyon for day hikes or backpacking trips.

The park's Backcountry Information Center (+1 928 638 7875) has the most up-to-date trail information and issues backcountry camping permits.
