In Palm Canyon how about the Maynard Mine Trail in the Indian Canyons Reservation site. Its in the sun most of the time, provides a chance to see the canyon area from above and doesn't get packed with people. You will have to pay the gate fee of about $8 I believe. A short 100 ft walk above the mine opening will bring you to a great spot to sit and view down into the canyon multiple waterfalls.
Another option might be Murray Peak. There are a multitude of routes to use in getting and leaving it. The fastest way up is from Rim Rock Shopping Center via the north face. The most scenic route is one that would take you up from the south side. You could start out off of Bogart Trail.
You could also just mosey up the first 2000ft of C2C and return.
