We were staying in the Zimbabwe side of the Victoria falls town and took a cab (all rides $5) from our hotel to the park entrance. We paid for the entry fee with credit card.
After entering the park, we looked at the map and realized that the view points were like an arc that extended along the ridge. There are 2-3 to the left of the entrance and the rest to the right.
We spent about 4 hours in the park going from end to end. After our visit, I changed my clothes in the restrooms in the park and we took a cab back to our hotel.
