<human>:  I am planning a road trip to the Grand Canyon. What is the best route to take?
<bot>: The best route to take to the Grand Canyon depends on your starting point. If you are starting from Las Vegas, it is recommended to take US-93 South to AZ-64 and then go east to the Grand Canyon National Park entrance. If you're starting from Flagstaff, take I-17 South to US-180 and then go north to AZ-64, and then east to the Grand Canyon. For other starting points, you may use a route-planning website such as Google Maps, to plan your driving route to the Grand Canyon.
