I love hiking in the Santa Monica Mountains! And now, after hiking to Eagle Rock from Topanga State Park, I can't believe that it has taken me so long to hike it. It is a hike that is doable for almost anyone as it is 4.5 miles on a roundtrip loop and only about 800 feet in elevation gain. Once at the rock, there is so much to explore, even some hidden caves that are a perfect place to relax and have a picnic.
