Head inside the Hollywood Hills and you will be pleasantly surprised by this man-made reservoir from where you can get a great view of the Hollywood sign. It is amazing to realize that this peaceful spot is only a few minutes away from bustling Hollywood Boulevard. There is also a 3.1 mile paved trail around the lake that takes you right across the dam (which broke and flooded Hollywood in the movie Earthquake). No dogs are allowed, and the path usually closes at dusk.
