Unless you are staying at the Main Lodge, there are no cars allowed in the main canyon. A free shuttle bus leaves from the visitor center and makes nine scheduled stops along the six mile road. There are great views and hikes along the way.

I am not sure how busy the park will be in April, as we were there in the fall after school had started. I would think in April, the weekdays would be less busy than the weekends. According to the website, the shuttles in the park begin in March, so you will not be able to drive your vehicle through the main canyon. But, the shuttle system is great to get you from one stop to another. There is never much waiting for the next bus. We preferred it to driving in the main canyon. With regards to the Narrows, we are two fairly fit 50 year olds and we had no problem doing the Narrows. The riverwalk portion is paved and no problem at all. If you are going into the Narrows, you need to rent waterproof shoes and walking poles. I would never attempt it without that equipment. The rocks on the bottom make it very unstable and we appreciated having a solid walking stick. You can rent the night before and return after you are done. About $25 per person. I would allow a couple of hours if you are just doing the riverwalk portion. If you are going into the water, then 4-6 hours. And, you will need to check the day prior to make sure there are no flooding issues in the Narrows and how deep/fast the water is flowing. The other three places you mention are not visible from the road. You need to hike to these locations. But, you should have no problem doing it. Those are all relatively easy hikes. I would estimate a couple hours for each - if you are hiking and stopping to take pictures. They could each be done a bit faster, if you are willing to really "hoof it." Have a great time. We LOVED Zion!
