Shortly after the Third Island of Tres Islas the river starts to pick up speed again. At the beginning of Roller Coaster there are two pour-overs. They are easily spotted in the center of the river with a channel on both and distinct eddies formed behind them. A long rolling wavetrain leads to the start of Class IV, Honorable Mention.

Low and High Water

At low water Roller Coaster flattens out and at high water the rollers wash-out.


Easily scouted from the wave-tops as you paddle.


At low water there will be two holes at river-center. As the water drops further they will become pour-overs. At high water they are wave-holes.

Play Opportunities

Some of the waves offer smooth, catch-on-the-fly surfing opportunities for boats with sufficient hull speed.

Where to Swim

Try to get to the river-left shore before Honorable Mention.

Where to Rescue

From the eddy on river-left above Honorable Mention.

Where to Portage

There is a trail that runs along the river valley on river-left, however this rapid is too long to consider a portage.
