Oh it's true that it can be dangerous.. but that's why I highly recommend to get a local tour guide and follow all the advices they will give you there. Some people thing they can do everything and this is when mistakes happened. Rather than saving money with a tour guide, it's important to pay for it and accept when they say it's bad time to go somewhere or the road is not safe enough.. Thanks for your link! I will have a look and leave a comment soon!
