This trail is really cool because you go through a oak tree forest, and the single track on it is at times a foot deep.
How to get there:
Take the 14 freeway to the San Fernando exit, which is a big loop. Look out for the cars parked at a dead end. Park there and ride up the fire road. Its about a 2 hr hike then you will come up on a single bathroom hut and off to the left is the trail. The trail ends at the nature center so have a ride waiting.
Have fun the hike up seems endless but it is worth it.
