Summer trip recommendations (CA, AZ, NV or UT)

Hey all,
trying to get a group of friends to go out on a weekend adventure and get them hooked on pack rafting. Looking for a weekend trip in the SoCal, AZ, NV or UT area with some gorgeous views and great paddling/hiking. Looking for an ‘easy trip’ to ease them in. None of them have proper packrafts and will either be rent but more likely using IK’s so nothing really more than class II-III rapids. Also, wouldn’t mind throwing in some canyoneering (nothing too crazy as not all of them have a lot of canyoneering experience). Looking for August-Sept time frame most likely.
We are all based in SoCal, so closer to SoCal = more time out in the wild.

Any Suggestions?
