Until early November one has to take tram into the scenic upper Zion canyon. But cars can stop along the SR-9 road through the tunnel toward the eastern gate of the park. Their are great views around Checkerboard Mesa and near tunnel entrance with short hike from car to Canyon Overlook...and other sights along that road. If you want to escape crowds go to the Kolob Terrace area of the park where several nice trails and beautiful high country...and few people. You can also drive into Kolob Canyon from along I-15 near New Harmony and great views right from your car.
Currently the shuttles are running from May 14th to November 13th, which makes it so you can't drive through the main section of the park. If you go to the east side you can drive through the tunnel as well as stop at several of their pullouts and even do some hiking. Chances are high to even see some big Horn sheep. You can also go to the Kolob section which is at exit 40 on i-15 near New Harmony. It is about a 5 mile drive up a very scenic road to a gorgeous look out. There are also stops along the way and little hikes you can do. There is also the Kolob terrace section (not to be confused with the Kolob section) that will take you to the Kolob reservoir. You turn off at the small town of Virgin on the Kolob Terrace road to get there.
