There are several roads leading to Hollywood signs, basically parking in the parking lot of Grifith Park. The parking lot is located at the foot of the hill and then climbs up the hill. From the parking lot to about 4 miles, it may be 5 to 6 kilometers, at least one and a half hours to climb. But half the way, you can pay to ride instead of walking. And the scenery along the way is very beautiful. You can see the whole Los Angeles and the park itself, including the mountains, rivers, canyons and so on. And many local people like to visit here. It's only 3 miles to the observatory.
