We went there to experience river rafting, when we pass the road it was awesome jungle. We were biking going there about 2hours,a little bit harder when we almost reach area for registration. Safety was implemented before doing the rafting, it was great experience because the water was 26' c and it was in the middle of the jungle, but when the last rafting section and we passed the houses and it was terrible smells, i vomited, i smells the poo of the people from there bathrooms, anyway they don't care so much about lavatory cleanliness which is number one for me. If I can choose I rather stop in station 5, because it smells good but we'll I cannot choose though because it is in the middle of the jungle. Try it but cover your nose. Tips. Do not but the ticket to thier office very expensive, but the River rafting ticket in the agencies there it is cheaper. Bus ticket also for long distance travel.
