This is a good hike, with lots of fantastic views, and not too difficult. Having said that, if you do attempt it try to leave early in the morning so you can find some parking, because parking in Runyon Canyon is kind of a nightmare. Otherwise you might end up hiking quite a ways from your car in addition to the mileage you gain on the trail itself. If you get lucky and find a spot to park, make sure to check that is actually allowed so you don't get a ticket. The views of L.A. along the trail are beautiful and you are rewarded with a 360 degree view of the Hollywood sign, Griffith Observatory, Downtown L.A., and you can see all the way to Century City and Santa Monica if it is a clear and sunny day. You can also plan on seeing and meeting lots of people and lots of dogs. Dogs really are the superstars of this trail, and you will probably get to see so many cute ones walking with their urban weary owners. Bring water, hats, sunscreen, and all the provisions necessary for a potentially hot and sunny hike. Although heavily traveled and trafficked, this is still a sweet work-out and respite from the city.
