We had planned to do the Zuma Ridge Trail, but when we arrived, the Zuma Loop, Canyon View, and Ocean View Trails looked much more inviting. I forgot to turn my GPS on, so I don't know exactly how far it is when you combine those three + the Zuma Canyon Trail, but it was a nice walk. I think about 5-6 miles. Lots of sun, lots of shade. Very well marked at very junction. There's a nice long ascent on Canyon View with gorgeous views of Zuma Canyon, and Ocean View Trail offers pretty spectacular view of -- you guessed it -- the ocean + PV and Catalina Island.
It's close to Malibu, so you can hear the traffic on PCH from Ocean View Trail, but nowhere else in the Canyon. Of course, that also means that if you live on the West side, this trail is right around the corner.
Great moderate trail for the location. 5 stars.
