South Rim is the closest to Sedona - Also has the best views
The most beautiful place to see. Worth a trip! It does require a Navajo tour guide. I've attached the link to where you can sign up for a tour.
You don't need to purchase a tour for this and it is also right next to Antelope Canyon.
Right in Sedona
This is a hike you can do at the Grand Canyon. It would need a full 2-4 days of devotion though as the trail is a full day long.
Cathedral Rock Trail
A city about 45 minutes from Sedona. Has their own amazing views as well.
