I consider my stay there as an adventure. Great place in the middle of nowhere, breathtaking views, lots of pure nature around, beautiful waterfalls, etc. The electricity all over the camp comes from the power unit which they switch off after 11PM so take some torch with you if you do not want to go to sleep earlier. An interesting thing- they have wireless internet connection over there (satellite I suppose). Be aware of the fact that you stay on Gran Sabana so some strange creatures can appear in your room. But you can always call one of the friendly Indians who run this camp to remove it from your room. But if I were you, I would leave alone the small lizards sitting on the wall- not only do they no harm but also they eat mosquitoes and tiny flies called Puri-puri. These insects are much worse than mosquitoes, there are lots of them on Gran Sabana.
The food that is served in Kamoiran is one of the best I tasted during my stay in Venezuela.
It is only 100 km from Brazilian border- worth to visit.
