I wanted to mention a great resource for waterfall buffs who are planning a vacation in the Western part of North America. Leon Turnbull's website is all about waterfalls. He is a very good photographer. And his website includes some charming out-of-the-way places that are mainly known to local people.
Turnbull's website lets you search for waterfalls in the geographic region of your choosing, and then he tells you how to get there. Sometimes a strenuous cross-country hike is necessary; at other times, the waterfalls are more accessible. Here is the link:

Here is one small example. Bassi Falls is in the Northern Sierras, approximately 80 minutes from Sacramento. I did the short hike in to Bassi Falls several years ago. Since then, a reasonably good road has replaced the old Jeep trail, and the walk is even shorter.
