Griffiths Observatory in Los Angeles

The City of Angels.
It's a place I've visited a few times in the past due to growing up for a time in Central California, but in all those visits, walking was not an activity I really engaged in. Friends and family with cars always shuttled me around when coming to visit. For good reason, as Los Angeles might be the most car-centric city in the world. Cars are the dominant force on the road, and everyone knows this, so you really must be aware at all times of traffic signals and the potential for cars to make a right turn into your walking path.
It's a bit unnerving.
All that being said, West Hollywood is actually a nice place to walk around. My friend happens to have an apartment near a lot of neat tourist destinations, all of which I shunned in favor of hiking up to the Griffith Observatory about an hour and a half away from her.
