Lots of climbing and switchbacks. About half of the trail is in the shade, and half in the sun. There are also a good amount of hikers on this trail. A little ways into the ride you should come to a sign that says Main Divide Road and Falls, you can take either one, but I would recomend taking Main Divide. You can take this trail all the way to Santiago Peak where you can see nearly all of Orange County and Lake Elsinore. You can also hook up with other trails from the peak like Cold Water, Main Divide, Modjeska, Horsethief and Indian Truck Trail.
From Orange take Chapman east. It becomes Santiago when you pass Jamboree. Continue east until you reach Cooks Corner and turn left. Continue past O'neill Park until you reach Rose Canyon. You will cross over Trabuco Creek Bed and there will be a dirt parking area on the left. There is a dirt road there that leads into the canyon called Trabuco Creek Road. You can park there or drive up the dirt road and park closer to the trail if you have an Adventure Pass. When you get to the Trabuco Canyon Fire Station there will be a bridge and a Y. The right leads to West Horsethief Trail, the left will take you through a residential type area and Holy Jim. The trailhead is at the end of the road and is clearly marked.
