This hike accesses the Ocean Trails Reserve on the Palos Verdes Peninsula from an obscure entrance on a residential street. The beginning of the trail – which passes by a housing community fenced off with barbed wire – might not seem inviting, but almost immediately, you are rewarded with great ocean views. The trail turns right (west) and heads downhill along a cliff that drops off suddenly to the ocean. And no, there isn’t a railing separating the trail from the cliff, in case you were wondering.
After half a mile, the trail reaches Shoreline Park and briefly its route with another trip described in this blog. You pass a vista point with picnic tables and pick up the steep Sagebrush Walk trail, which climbs quickly to meet the Gnatcatcher Trail. Take a left and continue along the ocean, passing by a few intersections before arriving at the Switchback Trail. This trail lives up to its name, quickly descending to the ocean. At the bottom, head right for a short distance and come to a deep canyon, with a wooden footbridge high above. This is a good turnaround point, although of course you can extend the hike along the shore in either direction.
