We recently took the trip down the river through the canyon. Yes, the canyon is beautiful but I could not enjoy it because of the remarkable sea of garbage in the river. I did some math as we were buzzing along with 20 people in the boat. I counted about 40 other boats. After doing some calculations, I figured that the government could have the tour operators contribute something per tourist to clean this up. It's absolutely shocking. If you go to Youtube and enter "garbage in sumidero canyon" you will get an idea. It is a sea of plastic garbage and other debris. The ecological implications are beyond belief and seeing the tourists just happily going along through the sea of garbage really bothered me. As tourists, we do have some power as far as our dollars spent. I wouldn't recommend spending money on this until there is some clean-up done.
