This was a research trip for KE Adventure to Roraima and Angel Falls, my kind of work. We trekked to and climbed up the flat-topped tepuis (mountain) called Roraima, inspiration for Conan Doyle's 'Lost World.' The vertical sides of these tepuis are not usually scalable but in this case a fault line cuts diagonally across the face allowing access to this strange and pre-historic world with its strange rock formations and endemic species that have been cut off from the rest of the world for millions of years.

After a flight in a small plane to Canaima we travelled by boat upriver and slept in hammocks below Angel Falls, the tallest waterfall in the world. In the morning vultures roosting in a tree were spectacularly silhouetted against the sun-lit rock face and waterfall.
