The car was packed with people & we were headed from SLC on a one day, whirlwind drive through trip of Zion and the Grand Canyon.... nothing special, just getting away from the city to see some red rock. Headed down the interstate, out running a hail storm, and 40 miles from Zion, we saw signs for Kolob Canyons - exit 40 off of i-15 South. Of course we had to stop, and boy were we glad.
It turned out that Kolob Canyons was actually part of Zion! You'll need to show an interagency pass or pay the Zion fee at the ranger station. From here you can take a 5 mile scenic drive through the 2000 ft walls. We were getting out of the car every 30 seconds just to revel in the beauty.
Once we got to the top where the road ended, there was a trail the looked like it went to a pretty sweet overlook. Too bad that hailstorm had caught up with us at this point, so we snapped a few more pictures and began the chase to Zion.
Unfortunately, this road doesn't connect to Zion, but its a quick jaunt back to the interstate. It is truly worth the quick pit stop. You can easily spend 15 minutes up to an hour here. Plus if you need to buy a pass into Zion, I would recommend stopping here! At any point, Kolob Canyons was not crowded at all!
