River Levels and Safety

Our client’s satisfaction is a priority for us so, please read the following part to make sure you really qualify for this adventure.

Keep in mind that we are NOT a park and we operate under a completely NATURAL environment making it imposible for us to predict exactly or control factors as high water levels, currents or falls. Our guides are profesional rescuers that will take you to one of the most extreme and beautiful places on the Island. And they will teach you some basic techniques to do it in the safest manner posible. But it is very important that you follow their instructions step by step and that you are physically and mentally prepared for this kind of activity. If you don’t think you qualify for this activity choose one of our other options.

For this adventure good physical conditions is mandatory as this is one of the most physically challenging adventure on the Island. No matter how high or low the levels are.

CFS refers at cubic feet per second of water. 1 cfs is about 7.49 gallons per second. 100 cfs refers to 749 gps.


After 120 cfs it is mandatory that all participants lead a very active lifestyle and can respond in a high stress or dangerous situations. ( We will notify all clients the night before). If you think you might be extremely afraid or that you will remain shocked in a dangerous situation, please wait for the levels to go down. If you don’t think you qualify please do not risk your life or the guides lives for it. If you are thinking about it, it is highly probable that you do not qualify for this adventure at more than 120 cfs.

Prior visit is required after 160 cfs.

Sometimes people think we are overreacting with our standards and they choose to come even though they do not qualify. Many times when we get to the river they are afraid of the water and want to walk the entire way, which is sometimes imposible.
