The drive from the meeting point to the river was far more scary than the rafting! In a two-wheel-drive family mover, the tour guide drove like a madman up this steep, windy gravel road with dangerous drops off the side. I'm fine with those kinds of roads, and I'm not one to normally complain about people's driving, but that is not someone I'd want to get into a car with again. After that, we had to pass through private property to reach the river - not sure if that was legal or not - and then to make the tacos for lunch the tour guide put all the ingredients in a bucket and then mixed it with the oar not exactly appetising. Those things aside, the rafting was ok but fairly tame.
This was the cheapest rafting trip we could find, but I'd recommend paying the little bit more for something of better quality.
