Due to increasing controversy about the ethics of lion walks and certain other “animal encounter” activities and the practices of those offering them within the Victoria Falls area, Zambiatourism.com will no longer be featuring such activities.
Zambiatourism.com recently announced they would no longer be featuring any lion walking or similar activities on their website. They formerly advertised ALERT's Lion Encounter program, stressing the supposed conservation value of it -- fortunately, looks like they've changed their view on it. Good on you, Zambiatourism!
