Interpretive sites are one way to inform visitors of appropriate behavior while in the area. They may convey meanings and relationships contained in an area or site. They inform through personal experience and illustrative media, helping the visitor gain a deeper understanding of the land. It increases people's natural and cultural appreciation for an area. Interpretation takes many forms, from guided nature walks, informative audio or videotapes, road maps, to visitor guides or newsletters.
Interpretation is effective because it gets the visitors involved in actively learning.
So, by getting more of the senses involved, people leave your site better understanding your message.
