A pleasure to be shown the Wilderness of Tzin by this friendly, well-organized and highly knowledgeable tour guide who was able to answer all my questions about nature and turned my tailor-made tour into a wonderful and unique experience. Special plus: Zvika Livneh knows when to be quiet and when to talk, which is so important in the desert environment. (I have had tour guides who talked nonstop, so this was a relief!) His story-telling abilities sitting around the fire in the evening are second to none. Recommended :-)
