The trip that took us to the unusual table mountains called tepuys lasted only 6 days and we spent only two nights and one full at at the plateau. However we had some days in the rainforest surrounding the tepuys too. In my view the chance of meeting a dinosaur is much greater there than on the rather naked mountain tops. I think Arthur Conyan Doyle was thinking of the hidden valleys at the foot of Auyantepuy and the others here in Canaima when he wrote his book.
Motor canoe on the river Churun into "the Lost World". We didn't see any dinosaurs but the highest waterfall in the world: Salto Angel.
To reach the Roraima tepuy we had to walk a bit crossing Gran Sabana, or rather a corner of it. Actually this part of the savanna should be covered by trees but due to regular fire started by the locals trees never get a chance. Only along the creeks and rivers some wood survive. Some ornamental plants could be seen along the path.
We set out from a small village and walked for two days. Day one: crossing the Gran Sabana. We slept in tents - 1st camping site. 
The next day we reached the wooded scree at the foot of the mountain. Here we could see both Kukenan tepuy and Roraima. The right picture shows the vegetation-covered crack we climbed to the top.
