Almost three decades of living in Los Angeles and I only just recently experienced Runyon Canyon. I always thought of it as a dog park--and it does have that reputation, and I did get knocked over by an exuberant mutt--but it is so much more than that. Accessible from the Hollywood area, a round-trip two-hour hike along any of the paths of this park will provide you with majestic views of the city from numerous angles. Unlike Griffith Park--which I also love, but which can sometimes feel intimidating by its sheer expanse, Runyon Canyon is very manageable. It is easy to see where you want to go and how to get there without feeling like you're going to get lost or end up in a longer trek than you were planning on. If dogs bother you, however, Runyon Canyon is not the spot for you. There are a lot of doggies in this area and for much of the park they are not required to be on a leash. Also, the park is popular and generally quite populated so don't expect seclusion. Do, however, expect a nice bit of exercise and an extremely nice view.
