One Day in LA

I have a family vacation to LA in November with one full day to myself and I want to know if this route is too much. I would start in Anaheim, travel north to the San Gabriel canyons and spend some time there. Then heading west to Malibu/point dume for the rest of the day before heading back towards Anaheim. Is this loop too much for one day? Would I be better off staying out east or west for the full day? Thanks
