Free national park entry this weekend

The grand picture: Grand Canyon National Park, one of the seven natural wonders of the world, is Arizona's most popular park.

• It usually carries a $20 per person fee or $35-per-vehicle price tag.

Yes, but: Arizona has plenty of lesser-known but equally enjoyable national parks and monuments, including:

• Saguaro National Park
• Sunset Crater Volcano
• Montezuma Castle National Monument
• Petrified Forest National Park

Zoom out: Up for a bit of a longer drive? Our Axios colleagues in California, Colorado and Utah recommend:

• Death Valley National Park
• Joshua Tree National Park
• Zion National Park
• Bryce Canyon National Park
• Mesa Verde National Park
