Located in the heart of Puerto Rico's mountainous region known as the Cordillera Central, the
Upper Arecibo cuts its way through a steep-walled canyon just above the town of Utuado. Providing
roadside access, Route 10 (a major north-south highway that connects the towns of Arecibo and
Ponce) parallels the river for most of the section. The run sits in a beautiful canyon lush with
vegetation where homes literally hang off the steep walled banks above the river. Cement columns
of up to thirty feet form the foundation for these homes and you can literally see the
floorboards from the river.
This section is different from the downstream reach of the Lower Arecibo. It's a tight and
technical creek run, switching between boulder-garden and slot-style rapids with drops of up to
six feet. The gradient is fairly consistent except for a steep class V+ waterfall section.
As you approach a small concrete dam, the gradient rapidly increases and it's time to get out and
scout the next set: three falls ranging from 18-25 feet drops. In succession: the first
falls is ugly and broken but drops into a deep recovery pool; the second falls drops almost on
top of the third and is very technical. After this the rapids gradually calm as the river
descends into the town of Utuado.
If this section is running the upper and lower reaches of the
Arecibo should have sufficient water and are worth checking out.
