Crater Lake is a must if you drive on the 5 through Oregon. Be aware that as the winter approaches the roads get icy, snowy and the temperature drops at least 10-15 degrees from bottom to top. It's a beautiful peaceful drive to the peak of what was once an active volcano. The lake in contrast to the snow is gorgeous and makes for amazing photos but you do lose some of the ability to explore due to road closures. The visitor center at the top that has a gift shop, facilities, food and drinks.
