We used skyline drive multiple times throughout our visit this past week- each at different times of the day. I'm glad we did because the deer are much more active later in the day. There are multiple overlooks that you can pull over and take pics- totally optional. It's fun talking to other drivers at each of the outlooks to see what they've seen, what they've hiked, etc. We didn't have a problem with traffic, but you should definitely be aware of the weather before heading on. There is a 15 dollar charge, but if you keep your receipt, you can use it for the entire week.
