I'm planning a trip to the Grand Canyon. What are the best things to see?

The best thing to do at the Grand Canyon is to take a tour of the canyon and experience it firsthand. You can also explore the many hiking trails, viewpoints, and scenic overlooks that offer stunning views of the canyon. Additionally, you may want to take a helicopter ride or rafting down the Colorado River to get up close to the canyon walls. For those who prefer to stay on dry land, there are several museums and historic sites in the area that offer an educational look into the history of the canyon.
