On my trip through the Ugab River bed in Namibia I came across a herd of elephant what made me a bit nervous can you imagine?
If the elephants approach within this zone, switch the engine on, wait a few seconds and slowly back away. Don't switch the engine on or make sudden movements. This may frighten the elephant and cause a threatening or aggressive response.
Always respect the wildlife. I was lucky they just passed by and this was a moment I will never forget.
