I´d like to share a fantastic journey at Mount Roraima. This was a life-time experience as it was my first big trekking trip. I´d also like to thanks Roraima Adventures, a brazilian tour company based of Boa Vista (capital of Roraima State). They did a superb job organizing and have the necessary equipment (e.g. tents, slepping bags and cooking utensils) as well as awsome guides. I´d highly reccommend anyone to go with a tourist company that has good credentials. During the trekking, I saw some tourists who used local and unreliable tour companies lost. Another tourist got involved in an accident at the top of the mountain and was in serious trouble because his tour operator didn´t have a global cell phone to call the helicopter to rescue him. Unfortunately, the Canaima National Park didn´t have the basic infrastructure to receive the tourist (e.g. there are no bathrooms, electricity, and etc). But Rorarima Adventures did a great job making sure my group and I had the basics. The Trekking is long and exhausting. I only recommend it to people who practice some sports or have done long trekking trips before. The view from top is outstanding. It seems that you´re back to the prehistoric times.
