The hike to the Wisdom Tree and Hollywood Sign is apparently around 5km. Parking is possible on Lake Hollywood, see map below, where the [P] is. Apparently, most hikers know that it seems, but we saw some people who drove up Wonder View Drive, where there is no parking. Lake Hollywood Dr is really sloped and quite steep, but there seemed to be plenty of parking available at 10am and even at 2pm when we left. However, it adds quite a bit in altitude and length to the hike. Going with a 4-year (soon 5-year) and 7-year old, it tired them out quite a bit.

According to information site, it is a 265 m elevation hike. At the lake, the altitude is around 250m above sea level, so we parked around 270 m above sea level, then hiked to the start, which is at around 300m, and the top of the hill is around 555 m in altitude. The Wisdom Tree (Tree of Life) is around 518m in altitude.
