Ask before photographing people. Respect your guide's advice on local customs, gifts and compensation for services, and be aware of expectations you may create for future travelers. Also do not support deforestation, by purchasing only handicrafts made from managed forest and veldt resources. Ask your guide which species are threatened. Select tour operators and packagers who provide expert interpretive services, to maximize your ecological and cultural experience.
Many agencies now offer specialized products with world-renowned experts on many subjects.
