Underneath the layers of technology and civilisation, we all just want to run free with untamed wild animals. At least, some of us do. The others would prefer to push chihuahuas in strollers. For those of us who want to feel the adrenaline of swimming with sharks and running with leopards, rather than the safety of a traditional sarafi, good news! Extreme tours are on the rise and you can fulfil your dream of having adventures like Eliza Thornberry (minus coversing with animals).
