It's a short, decent trail with pretty good views.
Route:
The southern access is directly to the right of the entrance bridge right on the O'Melveny Park parking lot. From here there's a moderately difficult incline for about 500 feet, after which there's a relatively flat trail on a ridgeline, giving surprisingly good views of the park and the Santa Susana sierra to the west and to the south and east you get a pretty good view of Granada Hills and the rest of the valley on a day with good weather. This flat ridgeline trail goes on for about 440 feet, after which there's a moderate, but not very challenging decline for about 70 feet up to the Loop Trail. This last decline has a few wood steps to help hikers.
Trail description:
The incline and decline parts of the trail were very overgrown when I went in June. Lots of tall mustard blocks your way and you have to swat it away from you. There's also quite a bit of thistles which thankfully only tend to grow up to waist length, but they do grow into the trail so it's almost impossible to not get stung through your pants, so be sure to wear something thicker after the rains. There are two points in the flat ridge where the trail lets out to small bare dirt areas that can be a good place to take quick breaks.
Overall it's a short trail which can be challenging depending on the season and where you start and has a quick and satisfying payoff with the views. read more
