The hiking here is great, there are a few different trails that are more difficult and quiet, and the trail to the falls is beautiful. It has gotten more popular in recent years, but if you hike to the falls early in the AM or later at night and during the week, you can beat some of the weekend traffic. I recommend camping in the 100 campgrounds-RV lot, even if you have a tent. They are quieter and more private, and the other campgrounds go through main trails. The 300 campgrounds in particular is on the hike to the falls, so you will see people all day.
