Threading the thin strip of land between the East Observatory Trail and Griffith Park’s southern boundary, the unofficial but regularly traveled Firebreak Trail climbs a steep ridge from the Ferndell picnic area to just below the observatory. On clear days, the short but leg-burning ascent offers fantastic views of downtown Los Angeles and even if visibility is not great, the trail provides an interesting, not often seen perspective on the southwestern corner of the park, notably the two Observatory Trails and the Hollywood sign.

From the Ferndell picnic area, pick up the East Observatory Trail and almost immediately, just past the green sign reminding dog walkers to clean up afterward, look for an unmarked but obvious trail heading uphill through a grove of oaks. After briefly leveling out, the trail splits and rejoins just before the main ascent. Griffith Observatory, your destination, is clearly visible here but to get there, you have over 400 vertical feet to climb. A short but very steep and often loose ascent brings you to a bump where you can catch your breath and enjoy the view to the south. Vermont and Western Avenues in particular are clearly visible, cutting a straight path all the way down to the Palos Verdes Peninsula.

After a brief downhill stretch, the trail makes another climb, picking up another quick hundred feet to reach a junction just below the observatory. The Boy Scout Trail heads east toward Vermont Avenue while the Observatory Trail heads west downhill back toward Fern Dell. An unsigned trail heads northwest – an interesting option for a return – but for now, head straight and make the final ascent to the Griffith Observatory. From here, you can extend the hike to Mt. Hollywood or other spots in the park – but the observatory makes for a surprisingly satisfying hiking destination, especially when visibility is good. Not having to fight to find parking is a plus as well.

After taking in the sights, retrace your steps to the junction. For variety, try taking the unsigned trail immediately on your right (from this vantage point, the Boy Scout Trail is on your left, the Observatory Trail is on the right and the firebreak is in front of you). Follow it northwest under the observatory, through a grove of willow trees. This short but scenic stretch provides nice views o the canyon below – and as much solitude as you will find in Griffith Park.

You soon reach a clearing, with good views of the Hollywood Sign – but no obvious way out. Look for an obscure use trail dropping sharply off the plateau, descending over 100 feet in less than 0.1 mile to join the West Observatory Trail. From here, simply follow the trail downhill, half a mile back to your starting point.
