The first out and back portion of the trail is about 2 miles long. After that you have a few different options. You can continue to go out and back or do the loop which is about 19-20Km. The trail is all dirt.
There's a vast trail network here. If you stick to the main paved road leaving from parking lot, you can go 3-4 each way, up until you reach the Aliso Creek water treatment plant and a chain link fence. The other side of the fence is a golf course and The Ranch resort in Laguna Beach. Otherwise, about a mile into the paved road and at a toll gate, you make a right onto Wood Canyon (dirt) and this goes up north for about 3-4 miles. Look up a map of the area. Lots of trail networks off of Wood Canyon.
