Stay away from a literal translation. If you like safari ...don't have a mural of an African safari painted on your wall. Look to incorporate something slightly more subtle. Add a cheetah print somewhere... don't go crazy with it.... be subtle. Add colors that you might see in the safari , like the wood on your floor.... Add small items from your travels in a keepsake cabinet or on a table.
This look will last much longer..... You can change it to another style much easier than draping walls with trees and wild animals...
This is a beautiful example. The room's safari theme is clear but not exactly literal.
