Morro Canyon

Rope lengths were estimated, from the length of my rope and arm span. I did this in winter so the water was mostly frozen. You might be able to downclimb more in summer. Note that the local guiding company's site claims that there are 8 abseils. I think they don't do the lower constriction. "The trip features a moderate-difficult approach hike of approximately 2 hours with an elevation gain of about 480m and requires a good level of physical fitness. Once you reach the canyon there are eight rappels and many more supported maneuvers with the longest rappel being approximately 20 meters."
