Waterfalls that you can reach the base of

This post was in response to Waterfall Classification: What Types of Waterfalls Exist In Nature?

In choosing a waterfall to try to visit, I have trouble with all the classification systems I have seen. I am much less interested in the water flow, height, or shape than I am in whether I can walk or hike to the base or pool. I like to get close and feel the mist. Does anyone have a suggestion for a resource or search method that could help me find Pacific Northwest waterfalls that fit that description? I have found only one–Rocky Brook on the Olympic Peninsula.
