Depending on where you find your information some maps refer to this fire road and hiking trail as Mandeville or Westridge. This is one of several places where the fire trail and the hiking trail crosses.
For an easier hike the fire road is the best bet, but you will have to contend with the mountain bikers. For a more challenging hike the trail offers more elevation changes and better views. Either way on a clear day no matter what the name is you'll have a great view of downtown Los Angeles from here.
