The hike is a short, paved walk with amazing views over Griffith Park, Los Angeles, Burbank, and the Hollywood sign.
In Griffith Park, park along Lake Hollywood Drive and walk the paved quarter mile up Wonder View Drive to the start of Wonder View Trail. Here, walk through the yellow gate and make the first right after the road turns to dirt. Head up this unmarked single track path heading east up the mountain.
The steep, rocky trail ascends to Cahuenga Peak. A Half of a mile from the end of the road, it reaches a ridge running west from the peak. To the right, the trail continues up Cahuenga Peak. Take the left fork, and the short path will take you out to the Wisdom Tree. Look for an ammo box at its base. People leave letters and wishes inside of it.
