If you have never been to the Grand Canyon before, it is definitely worth visiting at least once in your life. It is considered one of the seven natural wonders in the world and the colors and the vast depth of the canyon are spectacular!
It took us about 2 hours to drive to the Grand Canyon from Sedona, and once there, we took the shuttle to the various lookouts on the south rim. My husband and brother-in-law had never been to the Grand Canyon before, and they were both awed and amazed by the natural beauty of it. There are many activities to do there, you can stay in one of the lodges/hotels, you can go camping, you can go hiking, or you can just take the shuttle from lookout to lookout so you can enjoy the nature and views around the Grand Canyon. If you are adventurous, you can hike or take a mule down to the bottom of the canyon. We did not do this, but I have heard it is a challenging hike (especially uphill)!
Looking at pictures does not compare to the actual beauty of seeing the Grand Canyon in real life. It is truly amazing, so go and visit!
