Park up at the Hollywood Reservoir Trailhead, and then follow the clear and straightforward trail which goes over the Mulholland Dam and then around the circumference of Hollywood Reservoir. The views of the reservoir are excellent, but the vistas over downtown Los Angeles and across to the Pacific Ocean are the highlight of the hike.

This is an easy hike but can be made harder and more iconic by adding on the trip to Mount Lee and the Hollywood sign.
