What I was doing was canyoneering, where you essentially going down canyon by hiking and rappelling down the pouroffs that have no way around. You hike into the upper part of the canyon, and in this case you need to swim through a couple of pools to the first rappel, and continue down by hiking and rappelling as needed. Then you can usually walk out the bottom of the canyon and head back to where you started. There is no rock climbing in particular, but sometimes a lot of scrambling.

I hope this helps
