A moderately difficult hike in Topanga Canyon State Park. Lush greens and beautiful views make this trail a hit! A 7+ mile hike from the Pacific Palisades to a popular overlook in Topanga State Park. The first part of this hike - the Los Liones Trail - is one of the most lush riparian canyons I've ever seen in the Santa Monica Mountains. It's gently graded, moderately shady, and definitely worth a look even if you have to fight crowds. Afterward, the trail meets up with the system of fire roads in Topanga State Park and makes a relentless ascent to Parker Mesa (1525ft). On a clear day, you'll get amazing views of the Santa Monica Bay, and often inland as far as the San Bernardino Mountains.
