Zion’s best kept secret is Kolob Canyon. Kolob Canyon is the northwest corner of Zion National Park and is absolutely beautiful, not to mention less frequently visited. Seriously, nobody goes here. It is a little far away, the only entrance is off the I-15, making it a much less traveled area of the park.
Despite the separation from the rest of the park, this area has some great hikes and beautiful views. Check out the writeup we did on it last year.
